Today I spend some time on stripping down my 2nd engine, with some great and some less great surprises...it nearly matched with my first impression when seeing 23 different kinds of screws placed to fix the head... but see yourself.
Some pics on the progress first:
Unfortunately one bolt broke in the head, will have to bore it out.
Cam's bearings look O.K.
Just minor wear on the chain tensioner.
Some pitting on the cam :/ which left marks on the very right rocker.
Rust in the first cylinder liner. It even attacked first the piston ring.
Finally splitted the case and pulled the crank out.
Crank's bearings look usable on both sides. The crank itself does not have any pitting or wear.
The pistons after a short ultrasonic bath. It turned out that the piston rings have tooo much clearance. I really don't know if I should use them for my first engine. New pistons will explode my budget...
The point is, that I have to drive with 34hp for the next two years after I will have gotten (hopefully next month if I get enough time for my last driving lessons...) my motorcycle license here in Germany.
Tell me about experiences using pistons with much clearance and your experiences rebuilding well running engines on low budget.
Regards,
Oette
