every single symptom you are finding, broken teeth, scoring on con rods, a bent crankshaft, etc. SCREAMS replace the parts. Do you really want pieces of metal spinning at 10,000 rpm underneath you. any wobble you can see is way too much and will destroy the bearings and has the very strong potential to send a broken rod through the case and into you.
Very good advise that I would personally take seriously.
Good luck with the fix:eek:ccasion1

eazy.
You get pieces of metal in between teeth and pull a wheelie.

Anyway i took the crankshaft to a shop they said its straight.
How ever 2-3 teeth were slightly bent.
Clearance is too critical for me to do any grinding but i tried anyway.
It did help slightly but i dont think its a safe aproach doing it this way so might as well buy another crankshaft.

2 problems buying another crankshaft.
#1 There is almost none on the market anywhere.
#2 its expensive.

Received used crankshaft and it has same problem.
One tooth was off, not straight telling me that they parted the bike for same reason.

Does anybody know if fixing one tooth is possible without replacing the entire crankshaft ?
There is none in the entire world that i could buy from, no one is selling it.
This one i bought from Netherlands

part is not returnable even from a dealer.
I just have to be patient.
I contacted some people on Ebay that are taking apart engine next week, so i can buy it from them for 1/3 the dealer price and with return accepted.

To return $250 crankshaft that came from Netherlands i have to pay $310 :lol:
No way i return it back what they should not have shipped.

I won brand new crankshaft from ebay for $500.
It turns smooth now against the clutch basket :)
I hope problem is fixed.

I also hope that case is not cracked anywhere. That would really suck my money out :(
Out everything back together and set the time and doing valve adjustment before i put the engine back on the bike.
Will see if it runs :)

Bike runs very nice. Quiet and smoother then before. Perhaps due to valve adjustment.
Have put on around 100 miles already.

Not pulling anymore wheelies on this piece of trash i tell you that :(.
Kinda defeats the purpose of the bike, dont you agree ?
