    Valves too tight or something worse?

    Hey fellas, just wanted to give a quick update, I've checked the exhaust valves using the clever drill trick dan mentioned, they are perfectly straight I'm just waiting on the rocker arms at this point... once those come in I'll get some diesel and wash everything out, then reassemble. Bob, I also appreciate everyone contributing to this thread, you guys are awesome and I'm glad you guys have taken something from this as well. Dan, I guess I should consider myself lucky the bolt didn't wreck me and the bike.. I read your post and remembered a few weeks ago I was riding solo flying through a trail at least 10 miles into the boonies, no reception going 50+ in 5th I heard a weird rattling in the engine and didn't think much of it as it went away after a few seconds. Now I am certain it was that bolt bouncing around... if it snagged it probably would have been my death as I certainly would have been pretty hurt with no one to help me. Maybe this engine maintenance isn't so bad after all since I at least caught the bolt before true tragedy struck because of it. Turbo, I know the rocker arms aren't at fault, I am for being negligent and you bet I learned my lesson. I meant to say I know how much damage rocker arm wear can cause and so I don't want to risk installing a sub-par part that could prematurely wear.

    I actually did get arrested while riding the bike.... and I snapped my collarbone 2 weeks later on my longboard. My clutch is operating perfectly so far so I will be reusing those plates. Thanks for the instructions i'll definitely be rinsing it out this week but you didn't tell me how to flush the pump... but I'm thinking cranking the engine might do that, correct me if I'm wrong.

    I've thought of my luck as being pretty terrible the past year or so... maybe I should reconsider haha, the camshaft alignment pin is a possibility.. I'll have a look tomorrow or monday. To bench test the pump where do I feed in the gas and do I just spin the pump gear to spin the pump? Thankfully the bottom end looks to be in great condition aside from the loose bolt and pin.

    Thanks fellas, I think I'm gonna go with an intense cleaning of the bottom end, bench testing and backflushing the crap out of the pump, checking and cleaning all the oil lines. I'll do frequent oil changes from now on and gut the filter everytime to look for shrapnel. If I find any then I'll prepare myself mentally and physically, pull the engine and do a full teardown. If there are any objections to that plan I'm open to suggestions. I have been using the service manual from thisoldtractor.com On the cheap chinesium rockers, I canceled the order and bought some much more expensive OEM ones from bikebandit earlier this week. I realized it would be a major bonehead maneuver to not only cheap out on engine parts but especially to cheap out on the part that caused this in the first place. Although this ordeal has been frustrating and a lot of work I am glad to have learned so much about my bike and feel a stronger connection to it already, and once the time comes again (hopefully soon) I know I'll feel more worthy of the insane enjoyment this little thumper gives me. You guys have been a tremendous help and for that I thank you again, I'll keep you updated!

    danman I'll check the size of the metal piece when I get home on sunday. Are you saying I can "bench-test" the pump with fuel as an alternative to dissecting it? I know I should give it a visual inspection but my engine is still in the bike and I really don't want to tear it out and split the cases man... to be honest I'm a little scared to do so. The more I take out the more I worry I'll miss something during reassembly... hell I don't even have a garage. I'm only a stubborn kid who impulsively bought a dirtbike 7 months ago... I know I signed up for this and I want to learn the ropes and take care of my baby but splitting the case intimidates the shit out of me

    here is the shift drum bolt

    Here's the shift drum bolt, does it look OK to reuse or should I replace it? Just a couple nicks at the bottom. Everything else looks mint as far as I can see.

    Also yeah I'll definitely be rinsing out the motor, I've gone this far so I might as well do it. What products should I use?

    I have removed the clutch and the clutch basket, the tiny pin is not the oil pump pin, that one was in place. I am now trying to look into the oil pump but the manual I have says not to remove the oil pump until I've split the case. Do I really need to split the case to have a look at the oil pump? I really don't want to do that...

    Also there's this tiny piece sitting on my clutch cover, anyone know what it is and where it goes? It seems to fit perfectly on this little slot on the cover but looking at where it fits into the engine it doesn't seem to be pressing against anything so it doesn't really make sense... Hole on the left is the kickstarter shaft for reference.

    I found the bolt, it's sitting under the oil pump a little behind it and it actually looks to be in pretty good condition. I'll take the oil pump out and see if I can grab that bolt.

    I gutted the filter and found some metal shavings in there. A small amount of them in the grooves on the outside of the filter and a miniscule amount of almost microspic ones on the inside. Based on the amount of metal on there and the amount that was shaved off the rocker arms I suspect most of it wound up caught in the filter, but I could be wrong. I have another problem though. I opened up the clutch cover and found that my shift drum bolt is gone..... . Obviously it's not actually gone but rather sitting in my engine somewhere, though I'm not sure how to begin searching for it. Any advice? I'll be tearing into the oil pump next.

    Definitely a big relief, my cash is quickly running out by now. I'm glad but somewhat confused as to how those rocker arms got so worn out while the cam lobes are practically untouched.

    Just picked up some calipers and checked the cam, both intake and exhaust are well within spec.

    Also the ticking started immediately after I took the bike on a stretch of highway for a few minutes, so yeah, high RPM's
