Thanks guys for the ideas of getting off the clutch boss nut.
Correct size ended up being a 1 & 3/16th inch socket.
after putting the motor on a ?sturdy? table adding straps to hold the motor from turning up when applying pressure and a pipe wrench on the old countershaft sprocket the thing came loose with body weight got so pics of the jerry rig.
Think I?ll use it to tighten too...
But now I?m at the piston ring gap setting procedure and according to the weisco instructions standard minimum clearance is bore size? x .004 equals clearance.
My 72mm = 2.8 ?x .004 =.0112? which is very very small
It pretty much seems already big enough the way they came. Has anyone ever had luck just throwing them in without shaving?
I don?t even think they have feeler gauges this small???
Kicker shaft is replaced now I just need to replace clutch disc and re-assemble...
Got my gaskets from UK finally after customs checked them
And I got some cool gear I can?t wait to show off. GasGas hoodie from GasGaspartsguy is awesome. So fresh
