Hi everyone...Long time reader, small time poster.. but i wanted to share some bad news with all my fellow 10rs.
Im bending over right now since since the dealer f***** me good last week.

Ill give you a brief history of my bike since i believe it contributed to my current situation.
After purchasing my 06 10r brand new from riverside Kawasaki in somerville ma, the first month was great. Until the forks started leaking at 2900 miles.
After much argument, and 4 weeks in the shop for a 2 hour repair, kawasaki covered the seals under warranty. they first said not covered as they dont cover fork seals. But having such low miles, kawi ended up covering the seals.

a month later i brought it to them to check a "pop" noise that i get under heavy breaking. I later found out that the chain was too tight. Odd especially since i never tightened the chain. However, the stealer couldnt find the location of that "pop" but upon checkout.. the mechanic says he hears lots of noise coming from the engine. And wanted me to leave it and have it checked out.
I asked him how long it will take, and he said it could take about 2 months to tear the engine down and find the "noise"...it was june 30th of that time. the heart of our Boston summer. the last thing i wanted to do is loose my bike for 2 months! He also said that if it was not something covered under warranty i would have to pay for the diagnosis and time to tear the engine down...well, i refused as i didn't know what kind of scam they were running and wanted a second opinion so i left with the bike.
after 3 weeks of riding later, catastrophe struck. While riding the streets of boston, my engine seized up with a loud crunching sound. well it didnt so much as seize but more of a crunch to a stop with my back tire locking up.
Towed to dealer. long story short, clutch basket bolts and rivets some how sheared off and exploding the entire clutch and basket etc... all into the oil pan.
the engine block, transmission, crankshaft, rods pistons etc.. all needed to be replaced. a major rebuild was needed to a 3 month old brand new bike with only 3700 miles on it. wonderfull.
the bike was at the stealer for 5 months. awaiting parts, awaiting rebuild
.
after much arguing with kawi warranty, they finally covered it. they initially said that since the clutch blew apart, its not covered under warranty, and that since i chose to ride it a couple months before when the "tech" heard noises i pretty much was negligent.. anyways after i sent a lemon law letter to them since they had it soo long, they "did me a favor" and covered it under warranty ( those exact words from kawis lawyer)

anyways.. so, i get my brand new bike back, with a rebuilt engine in december.. great.. so much for riding my brand new bike i owned for 3 months in the summer.

2 year of ownership went well,
3rd year had to replace some fork seals, but this time i did them my self in 30 minutes.
4th year.. more fork seals. and an added starting issue.. no fuel on a cold start with computer code showing cam sensor.
replaced the cam sensor, still no start. shot in carb cleaner.. bike fired up, didnt have problems for a month.
5 year ( this year, same year ext warranty expired) more start issues. brought bike to stealer 1 month before warranty expired to find the start issue. they had it for 3 weeks, couldn't find the problem, and blamed ME for my led turn signal lights i have installed and a fan switch i have jumped into the fan relay going to the ecu. since the "technician" couldn't find the problem of the no start, and why it set off a cam sensor code, he blamed the user.. his exact words on my receipt was " my gut feeling is all the garbage customer has installed" yes, led turn signal lights are garbage, and, they are somehow shorting out my ecu... real smart tech huh?

anyways, since they couldnt find the problem, they charged me $90 for their time to "diagnose" the problem, even though they didnt have the answer... so i take my bike back home and ride it for a month. now my warranty has expired.

3 days ago, went out for ride, stopped at starbucks, went to restart... no start. upon cranking, i noticed alot of back fires... almost as if timing was off.
tried my carb cleaner trick.. bike fired up.. but this time with what sounded like 13 monkeys playing drums on a tin roof...i immediately shut it down...
being a car mechanic my whole life.. what popped into my head was..."valves being hit by the pistons"
i pushed it home in 88 degree heat.

pulled off cam chain cover and found crushed up cam chain guide, the metal one that is part of the block... it seems my cam chain was so lose, it hit the guide smashing it... i reasoned that if it was so loose, it possibly jumped some teeth on the timing gear, leading to the valve noise...
i removed the valve cover to get at the cam shaft gears to check timing...
yup.. timing was off...it did jump a tooth.. maybe a bunch of teeth.... well.. that explains the back firing and hard starts... it also explains why the cam sensor code was being set during the no start scenario. A very loose cam chain.
but it gets worse.....

i decided to reset the timing, tighten the cam chain, flush the crankcase, and fire it up hoping that this engine doesnt smash the valves when the timing is off.
i removed the starter clutch sprocket off the crankshaft... and more disaster...the center bolt holding the sprocket on was either tightened with an air gun, or had permanent thread locking sealant put on by the "technician" who rebuilt the engine during my first engine failure.. so the bolt didnt unscrew, instead, the neck of the crank shaft spline.... split... yes, the crankshaft broke on removal of a bolt that was over tightened with an air gun or with some thread locking agent....clearly a fault of the person who rebuilt the engine a couple years ago...

so as it stands right now, i have a 06 10r with 13k miles on it, needing a crank shaft, and possible valves.. and my warranty just expired.

moral of the story, i hope that tech has a catastrophe like this to his penis, as well as the idiot tech who rebuilt my engine 4 years ago.

now, all this could have been prevented if the "tech" did his routine diagnosis last week..
for instance, when your a kawi tech, and a 10r that is known to have faulty cam chain tensioners comes into your garage, with a cam sensor code, you test the sensor, then simply remove the cam chain cover to see if the chain is loose, and adjust the auto tensioner as needed. clearly a cam sensor code should set off some alarm in a techs mind...and not blame the customer for led turn lights or fan switch.

long story short, if none of you have routinely helped your cam chain tensioner tighten the chain by rolling your bike backwards in 5th gear, then you may run the risk of a loose chain jumping teeth, and smashing your valves...

now, i have a few options.
1- get a lawyer and do the whole 9 yards thing of suing kawi, the dealer etc...which will take months if not years...
2- remove the engine and rebuild with a new crankshaft and remove head and put in new valves...
3- push it to the dealer telling them the chain is broke, and attempt a trade in with a non running bike . maybe ill get a couple grand for it. i owe $5800 still
4- try to sell it as is.. but not sure who would buy a bike that needs to have a crank replaced...



any ideas? any one else have a cam chain jump gears?
can any one confirm that this engine design does in fact smash the valves if the chain jumps teeth?

thanks for your input.. and think of me the next time you fire up your 10s today....



:crybaby2:

thank you..
my heart is broke.. i been walking around the last 2 days in a daze. theres no worse feeling than paying a loan on something you cant use or have.
i was looking at my kawasaki account and it shows i do have an available credit of 11 grand...
i have a good mind to just go there and get a new 2011 zx10
then deal with this one on a daily basis weather i want to sue, rebuild, or sell it as is.
but not sure what the market is like to sell a bike that needs works.
clearly this bike was a lemon from the get go...

Nothing feels better than riding on a brand new bike. Maybe that's what you need. After the experience you had with that dealer, I wouldn't go back to them until they can work out some kind of deal to trade your bike in and buying the gen4. You could also part it out or sell it as is to try and recoup some money.

Check out this ad in craigslist...not sure where you live but these guys are in Tiverton, RI next to Fall River. I was going to get this until I found a great deal on a gen3. I met and spoke with the sales guy there and he seems real easy to deal with. Talk to him and see what he says if you're interested. I think this is a great deal for a gen4 in our location.

Yeah i hate to go against the grain here but if this line is true
"being a car mechanic my whole life.."

Why are you trusting a extended warranty from a dealer that clearly couldn't give a shit about your bike and you have had fork seals, motor rebuilds done by them.

WOW you are a very trusting person.
If xtended warranty in the states is anything like here in Aus it isn't worth shit and it's a nightmare to get anything done because it's operated by third parties.

If your a mechanic Just rebuild the motor or buy a second hand one of fleebay or somewhere. It's the only way your going to get bike back on the road.

I feel for you really but there is a reason why i have never paid a mechanic or dealer to do any work on all my vehicles, because its a 9-5 day in day out job to them. Where as i put the extra care and time into my own stuff. Good Luck with which ever path you take.

agreed... the times i had to use the ext warranty for my problems, it was either denied, or took forever to get approved...i really learned my lesson on this one..
i dont currently work as a mechanic any more, so i have no tools, and no real place to do the work... plus my back isnt what it used to be..lol...
id have to remove engin in my back yard, then drag engine into basement to work on...

i think finding another engine would probably be the best scenario, especially since i was reading up on the crank replacement procedures... ugh....i dont have time for this.. i just want to ride hard, cut off cabs, honk at hot girls, pose at starbucks to lookk at girls, and do some wheelies.... i was so looking forward to this years bike week in NH...
now i know that sport bikes are welcome at bike week laconia, but i wonder what will happen if i roll up on my scooter?

You would make far more money parting it out than you would trying to sell it as a whole. Somebody would buy the motor-people like to tinker, build up crazy projects and have spares.

A used motor could probably be had for little money. I would go through it for peace of mind before installing it.

A new bike would be great-who doesn't like a new bike? You still have the old one to deal with though and a substantial amount of debt. Debut sucks.

I never bother with extended warranties... I usually void the originally in a few weeks anyway, and not just with motorcycles.

ill never forget the tech manager said that my wiring voided the warranty if kawi sees pictures of it... i said " you mean the 1 wire im using to ground out my fan switch to make it manual?" he said " plus the lighting in the back" (he was referring to my led turn signals) i said to him " you mean my led turn signals will void my waranty and cause my cam sensor to code up in the ecu?"... he said yes... i laughed.. then i said,,, " well how about if i were to come in with out warranty and pay you to diagnose my problem and fix it?"

he said, and i this takes the cake... "well we wouldnt work on yoru bike, we dont like to do jobs that take substantial amount of time"

my chin hit the floor and i said " so you would refuse to work on my bike?" he said yes....
so i said, "all you guys want to do is install exhaust systems and brake pads for the poor shmucks that dont know any better and charge them 2500$ for something that takes you 60 minutes"

thats when i pushed my bike home 6 blocks...

A 08-10 10R motor will bolt up to the 06/07 rame no problem. May wanna consider that option too.
 
#20 · (Edited)
You mean the starter clutch sprocket bolt the left side of the motor?
That bolt is counterclockwise and must have locktite if i recall correctly (on the gen1 it was for sure). [EDIT: I stand corrected, checked the manual page 537 seems normal and requires 155nM of torque but NO locktite, damn...]

Also from year2 to year5 you did not adjust your tensioner once?
Did the tech opened your bike the last time?

If you put the cam timing back (28 teeth) the valves should be ok generally if nothing major happened.

It's overall a very misfortuned case and i do understand your frustration.
Crappy mechanic for sure and must admit his faults. But if you are also a mechanic i would expect you to handle it abit differently, especially if you heard noises the first time, you could have saved the clutch damage, a teathoscope would do the trick easily, he should also know it. I also understand the mentality of not touching it since somebody else is responsible for it and you have paid for it.

Just saying not bashing you in any way man, it's his fault good luck i hope you get sorted out, hopefully with another tech this time :thumbsup:

well over the 2 to 5 years i did do the push backwards method... maybe not enough.. "Did the tech opened your bike the last time?"
if you mean when he tested for the cam sensor code, no.. all he did was test the voltage of the cam sensor and crank sensor. nothing else..
it was an intermitent starting problem at the time, and when i brought it to him it was starting fine. it sat for 3 weeks at the dealer and the only times they went to test to see if it WOULDNT start was when i would call.. they would say hold on let me check with the tech... then i would here my bike start up in the background, and he would get back on the phone and say " the tech is still chasing down the problem" which was BS.

"If you put the cam timing back (28 teeth) the valves should be ok generally if nothing major happened."

when i did get my bike to start when it died out last week, i heard a whole pile of noise. i immediatly shut it down.. i was hoping that if i could reset the timing i would be able to determine if that noise was the valves or the chain flopping around.. but alas, when removing the starte clutch sprocket, the spline of the crank split off...i gess ill never know unless i tear the engine down..


well when i originally brought it in 4 years ago, the noiise i was hearing was from the nose plastic clicking under heavy breaking.. it was not the engine noise that they said they heard...maybe i should have let them keep it to tear it down.. but when they said 2 months., and then saying i might have to pay for it, i was very reluctant to leave it.

now when i say i been a mech my whole life.. id like to clarify it was a car mech.. and i never went as deep as replacing crank shafts etc... so bike engines and replacing the crank on this is honestly a stretch i dont want to take.....oh well...
i know you arent bashing, i respect everyones opinions that why i posted, and that how i learn...if i did something wrong in this whole situation, ill make sure i DONT do it again for the next bike....sometimes it takes someone else like you guys to point out what i should have or shouldnt have done.

FYI, Suzuki is no better. I went round and round over a transmission problem on my 05 Busa. I'm honestly glad when my warranty is up on a new bike because then I know I won't feel the need to struggle with the dealer trying to get compensation.

I'd go with the used engine too.

When the cam chain tensioner got loose, didn't it make a racket for awhile before it jumped teeth? They usually don't just fail instantaneously.:dontknow:
well honestly... i never heard it make any noise...i wont say my exhaust is so loud that it drowns out noises, but, its possible. My pipes are kind of loud but i would imagine that a chain THAT loose would easily be heard....but i never did.


i found a 1500 engine on ebay from georgia it suposedly has 9000 miles on it.... im trying to work a deal with him to lower the price in some way....praying i can get him down to 1000 even.
 
#32 ·
right... then i can confidently say, that no cam chain noise was heard... especially if it was loose enough to slip a tooth.

MAYBE the noise i did hear when i did get it started was the chain flopping around, and not the valves being smashed. but i wouldnt run it as i didnt want to do any more damage then what already happened. but even with the timing off, it still would start. i was hoping to reset the timing and test it, but thats when i ran into the crank shaft issues.

i always well maintained my bike, i think it was just one of those that came off the assembly line with bugs.
maybe it was one of those built on a friday lol.
