The time has come, the walrus said, to wrench on many things...
At 155,523 miles, Thumper has been taken out of service for some semi-major work.
Reasons for work.
1. Using too much oil (compression isn't horrible though. Suspect valve seals)
2. Clutch slipping in 5th gear. Enough to aggravate.
To set the stage.
Mobil 1 was used until 60,000 miles. Rotella T6 since then.
Things that were done prior to this tear down that are engine related.
Verslavy put in and put on 2nd hole (miles unknown).
Cam chain replaced with Nitrided at 81,000
Verslavy put on 2nd hole at 105,000
Started chasing left side oil leak
Starter o-ring, 135,000
main oil seal and o-ring 139,000
alt cover gasket 142,000
Stator shorted 153,000
Boys and Girls .. THAT IS ALL THAT HAS BEEN DONE TO THE ENGINE to this point.
Other things have gone out. (Belt, carb slider x 2, carb float seat o-ring, front wheel bearing, rear pulley bearing, mufflers, etc)
Other things have broken from abuse (rear fender x 3, spokes, muffler bracket x 2, rear shock, etc)
So, why this post? So I can tell you what I am seeing as I tear this engine down.
I ain't near as eloquent as other posters, so just deal with that.
Clutch arm is right at the lower mark, indicating some wear is likely.
Clutch cover gasket. Hard as a ROCK. Cleanup is going to be a pain.
Cam chain tensioner.
Only 10mm out from the barrel??? I was truly expecting that thing to be at the limit of the Verslavy.
Cam. Looks good to me (should I take pictures?)
Cam journals. Look good too.
A little wear on the rocker arms.
More later
