97grnrs If you get another Gen 4 motor I'd leave it alone internally. These motors are built well and don't need much to go fast as I'm sure you know.. Gen one, 2,3 could use motor work but Gen 4 doesn't really need it, or just pop a used Oem head on yours and you should be back in business

C3L1CA I finally mustered up some energy to look at the bike just a tiny bit. It's been sitting since I last rode it and never even pulled the logs.

Looking at the log from when I had issues it looks like it either hit the limiter or got close to it and then for some reason the bike shifted from 4th to 3rd. I could've sworn it felt like the rear tire started sliding after I hit the limiter but wasn't sure how or why that would've happened. Now it makes sense it probably was sliding around.

Wonder if being on the limiter like that would've maybe moved the cam gears. I was watching a video brock did about how he lock tight on his kickstand bolt and he hit with brake cleaner and then hit it with compressed air. When I put lock tight on the cam gear bolts I just used a pick to pick out any old lock tight and used a rag to get as much oil off the bolt and inside the cam gear as possible. Maybe I should've been a little more diligent on getting oil off but I did the same process last time and had no issues.

I also took off each side cover and was not able to spin the motor over by hand. Driving the same road the other day I rode it about 1 mile down the highway until the exit where it died and log looked ok. Then after it died and I coasted to a side road I did have a log for about 3 seconds where I started it but it sounded bad so I turned it back off. Looks like it stopped pretty close to TDC for 2/3. I'm going to try digging into it a bit tomorrow and see how far apart I can get it and see how bad the damage is. Oil looked clean through the sight glass and smelled pretty normal after taking off the side covers. Coolant still looked very blue in the overflow.

I was talking with a guy I rode with a few times who has a gen 4 who was looking for an engine and he said the only thing wrong with his is he thinks the timing guides are bad as he tried to manually put more tension on the stock tensioner and pushed it in too far. Said he ran it for 15 minutes then it's been parked since. He said he'd take $1k for it. Depending what I find with my motor I might see if I can talk him into me pulling his motor for him and maybe putting in a new one for him if he'd take less money. I'd only buy it if I could do a compression and leak down test on it to make sure he didn't screw anything else up.

peterd10r A funny thing happened to me when I was moving my bike to its new home!I took it for a ride on the HWY to blast out some cobwebs and it started braking down as soon as it was over 9000rpm!I didn't turn the traction control to off and power mode to full as I did before as soon as I jumped on and started it and can't remember what settings it was on!hopefully this could be my problem and I just remembered I can check by simply seeing what setting it goes back too when the key is turned off and on!When I had the tank off recently I made sure the fuel line was in the correct position and hopefully it's not a crimped line!time will tell as this has never happened before but I have never forgot to change those settings!when your under the pump with things going on around you mistakes happen!the moral of this story is "take your time"

C3L1CA I still haven't dug into the bike yet. The week after it happened just had too much stuff going on with getting ready to go on vacation and I'll be out of town until next week. Tempted to see if I can get a weight on it even though it has a pretty full tank then see if I can turn it over by hand and then maybe pull a plug and see how that looks.

I've been talking about making a few nightstands for our bedroom and tv stand which has now turned into a cool hamper hider. Kind of want to get that stuff done too to get some things off my to do list and don't want a motor open while creating sawdust in case a good chunk of it is savable.

I'll post up what I find, hopefully its good news when I get to it. Fingers crossed.

Good to hear! Hopefully the afr is still in check as it sounds like its getting a lot more fuel!

looks good by the way
I almost sent you a PM but then wasn't sure if it'd be too big of a pain in the butt. Good to know for next time or anybody that sees this thread

Bad news on my bike though. I started it on 4/18 late at night to make sure it started without issues as I was hoping to make a track day on the 20th. Bike started and let it idle for a minute and everything seemed good. Finished putting everything back together on Friday and was doing some street tuning and things from my old tune had it pretty close, I threw more fuel up top before making pulls and it was actually rich in some areas. Did a rebuild on the front caliper too as it seemed to be dragging more than I would've liked when putting it all back together.

Went to a good friday thing at church, picked up some fresh 93 on the way home and skipped going out to eat with the inlaws. Came home, did a little rip and it seemed to be quick. On the old hookup it spun in 2nd once it hit the powerband. In draggy i was able to get a 3.93 second 60-130 starting in 3rd. I was kind of glad it broke into the 3s starting in 3rd as seems most guys who are in the 3s are probably starting in 1st.

I was out doing one last log and did a 4th gear pull and just hit the limiter for a split second shut down and at the light right after getting off the highway it sounded like it was making some sort of noise. Got going a bit and bike just died. I was able to coast down the road to a side road and I did start the bike up for a second just to see if it would then shut it down quick as it didn't sound right. All the mods to reduce rolling resistance made it a pretty easy task to roll the thing to the gas station half mile down the road

Think the little guy liked the green and it was growing on me with the side winder too for some reason. At least the guy at the gas station said the bike got a lot of attention and lots of people were taking pictures of it he said. Felt weird leaving it somewhere with no head lights, no key/ignition and no plate lol.

And here is where its been sitting since 4/19.

With working on it every night for a week kind of burnt me out and have some stuff to do around the house. Kind of want to weigh it for fun before start taking it apart. Figure first thing is to pull the timing cover and see if it turns over by hand. Oil in the sight glass still looked good. Hopefully its nothing major, otherwise I might see what I can sell to just get another motor in there and make it to a track day in the fall.

mpp12 C3L1CA,

you would have spent half the money with my mechanic.... doing the mood... I have a few boxes here laying around, you would just have to wrap it...

And yes it takes a lot of work to do that mood.
