Piston size

[daddyrat]

What a saga!!
I decided to just do the rings, valve seals and while I was at it to replace clutch springs as per a previous post from Roon. Took it all apart, engine has to come out.:-(, cleaned everything from all the soot, checked shims , they all where tight, inlet by quite a margin, and ordered parts.
Gave piston a miss due to price and the old one was still really good. NO! wear marks what so ever.
Put it all back together after reseating valves =, installed engine and then discovered it would not turn over. Something was stuck!
Eventually discovered that the timing was out by three teeth and valves where touching piston. Out again, this time checking TDC with flashlights and thru spark plug hole aswell, fixed cams, put everything together and she's running fine.:-))
No smoke, no nothing. smooth as and a really soft clutch! Riding tomorrow!!!

You can lock the crank at TDC with the little bolt in the sump under the oil filter. (pg 17 in the service manual.)

The motor does not need to come out to remove the cams or adjust them.

Riding again
