The thrust washers keep the rod from rubbing against the crank weights. Once the washers go the big end is already toast. The only way to correct this is to replace the rod assembly.

Unless the material is left over from a prior failure. Who knows. It may stop running shortly.

You might get by with an eBay crank. Although you would want to replace the bearings while you are in there to, so it might be better to just redo your crank if you can find someone to do it.

I am sure Steve knows someone and will likely chime in soon, if he hasn't already PM'd you.

yeah this might take some time. thankfully its an XL600RM, and i CAN find parts RATHER easy, funds however, are another problem ;). I'll probably replace it with an XR600 engine for now, and do the rest during the winter or when i have time.
Does suck that i'm going to have to dump a lot of money into this engine. oh well...

CDI's are no longer available from Honda ( I think I got the last one, the Honda guy said don't ask for another), but I ran a CDI from a '94 XR600 for a while and all seemed good. Same connectors, just plug and play.

Can the case be split from the flywheel side and leave clutch and tranny intact?

You'll get it apart but I don't think it will go back together due to the spring loaded counter-balancer.

Just wondering if there was an easy way to do center case gasket.

There is no easy way, If I remember correctly you stack the tranny and shift spindle and everything in the left case, then drop the right case on. I can just envision disaster trying to keep it all together in the right sidecase, opposed to the small amount of time it would take to just strip the right side down and do it as designed.

hey, sorry about the picture size, I tried to decrease the size on imageshack, but it apparently didn't work as planned. So, I finished cleaning the carburetors in Pine-Sol, then washed with soap and water, and finally blew out with compressed air. The carburetors are like new again, and after re-installing. I discovered that I sometimes have normal feeling compression and other times I can just kick it through without pulling in the decompression cable. This is concerning to me. I followed the manual on how to put everything back together. Thanks Schrauberklaus for the input and dave. Unfortunately I don't have a compression tester, but before my fatal ride, it was hard to kick or better as they say, and started perfectly every time. now it is either hard to kick, or freely kicks through which is worrisome. I adjusted the idle screw so that it is closed. I fear that I might have to do a valve job. I just checked my adjustment and it is .05mm for intakes and .1mm for exhaust as per manual. Any input would be appreciated, thanks

-Dan
