WR400 - adjusted valves - kick over lockup
Posted April 05, 2005 - 12:43 AM
I' changed my rings, lapped my valves and adjusted them. I did my best to do everything right and I feel I did. When I went to kick it over (not to start it- just a check), I was able to cycle the kick start a few times, with the decompression lever pulled, and then it locked up! Now the kick start won't budge, even with the decompression pressed down. What should I do to trouble shoot it?
I'm thinking the decompression lever, maybe?
Or the timing "I" line up... that was strange. I got the pin marks on the cam gears flush with the case like the picture in the manual. Is there something funky I don't know about? How do you line up the "I" - does it take so many cycles - could it be on the wrong cycle? I'm clueless and bummed.
I hope I didn't bend the valve onto the piston or something - if that is possible? It never started though.
THanks for your help!

I did ball the chain up once finding the "I" top dead center when adjusting the timing - I was like what the is going on. Found out that could happen and corrected it. Maybe that tensioner didn't pop out (almost certain it did). I'll just wind it up some and see if it spins out on its own.

I turned the crank with a wrench, counter clock wise, while watching the the timing indications. When it goes past the letters "F5BF" it makes a light shhh/kk noise but will spin all the way around and around. When I move the kick start it locks up right around the letters "F5BF". I'm guessing its the lobes pushing the valves at the wrong timing. I'll open it up and see if I screwed up somewhere or if it's balled on the chain.
son of a bitch
thanks for the tips

I checked the timing. It seemed to be off, so I set it again like I did before E's to the left - dots on the outsides/flush. Then I turned the crank around one time to line up with the "I" again. I noticed that it was off again, but it's not. I guess it depends on how many revolutions to the "I".
How do you know which is right?
Anyway, with the kick start I noticed it locked up when the exhaust valves were pushed at the maximum. I could turn it with a wrench/ratchet but makes a light grinding sound. So, I thought there might be the wrong pad/shims under the caps. I took the cam off for like the 6 th time (serious) and inspected the caps and pads - seemed fine.
I left the cam off and held the chain with my hand, so it wouldn't ball up the chain. I zip tied the decompression lever down (the pin pushed the valve open to release air). I tried to push the kick start and the same shit happened - lock up. I guess that eliminates a timing problem..?
I didn't want to have to pull the cylinder!
I don't see how it could be the rings. It's locking at the same point too (F5BF point on the timing look hole).
