By slop in the wristpin needle bearings I guess it isn't as bad as I thought. On second look the "slop" is side to side, it just seemed like a lot of movement to me. I pulled the pistons off and rotated the crank while holding and "thumping the tops of the rods trying to feel for play in the rod bearings, the only play I can feel is them sliding side to side. The worst one is the left side. It moves aprox. 1/8 of an inch. Is that the knock? Or is that normal? Do you guys think its just in the top end? The pistons and cyl's are scored, but not really bad.I will replace them but theres No broken skirts or anything. the only gear under the clutchcover that has a little play is the one between the kicker and the large gear behind the clutch. So I got book. And answered my own question. Way out of tollerance! I'm wondering if I should buy a crank or have this one rebuilt. Havnt checked out prices yet.ugh... I really didn't have the time for this but I'm sure it will cost a lot to have someone else do it.

Pulled the clutch cover everything looked alright. Pulled the top end. The left cyl was 10 psi lower. 110 and 120. The pistons and cyl.s look about the same. But I was surprised by how much slop the wristpins have. Should there be any slop there? also How much side to side play can the rods have on the crank pins?(If any) They are both about the same and I can slide the rods side to side on the crank pins maybe 1/8 of an inch.

what do you guys think i should go with for the top end kit? i've always had good luck with wiesco on other projects.

If one cyl is 5psi or more different, then that indicates a problem in the topend that could be related to the knock Alright. So I've got 110 and 120psi. Guess I'm gonna yank the topend apart. Hopefully the bottom end is alright.

Alright. I do hold the throttle open though right? If one cyl. Is low would it be knocking because of that? I'm just hoping I don't have to split the case.

Alright, so I kicked her over when I got home from work and shee came to life first revolution. No knock...for about 30 seconds. Clutch engaged, in gear doesn't matter. The knock is solid. Using a dowell I can hear it througout the engine it doesn't really seem any louder from one side to the other.from front to rear of the block. (Of course I am half def from years of eardrum abuse) so I've got a compression tester on the way. Correct me if I'm wrong, pull plugs, hook it up and test each one with throttle wide open? what should it have for compression?

great thanks guys. honestly I dont know if it does it when i pull in the clutch or in gear. i will try tonight. i did buy a book yesterday. again thanks so much guys i will post after I look into it a little more.

alright so heres the scoop, i picked up this 02 shee and it was running great. now it seems to have a slight knock in the bottom end. and it doesnt want to idle. its not a hard knock, but i cant really tell where its coming from. the crank or farther back in the tranny. thing is, the guy i got this off said that he had just changed the oil in the trans. and im wondering if he used the wrong oil and really munched this thing. i pulled the plugs and turned the engine over by hand to see if i could feel any friction thinking maybe a rod beaing had failed but i cant seem to feel any. I had a blaster do that once and the crank rubbed on the case. anyways, any input would be greatly appreciated.
