New cylinder, now drive problem!

Postby Sunbeams7 » Wed Apr 25, 2018 6:52 pm

Hello folks.
Just fitted a new cylinder, my old one had gone oval bore for some reason.
Anyway fired it up an all ok, rode half way down the road and the bloody thing started rhythmically clunking from the gearbox!

It’s like the cruciform isn’t doing it’s thing properly and gearshift has become awkward.

I did remove the selector box to get engine away from the frame ( maybe should’ve just undone cables)
but batwing appears to conform with hand shift.

Have adjusted clutch to how it was before.

While all this is happening the top end is running fine.

The only thing that puts me about is the way gear selection works on a scoot, and so I’m wondering....what’s the most obvious academic mistake I could make regarding this.

Any help appreciated.

Right so, clutch covers off and output shaft seems stiff and gripey to turn by hand.
Guess it’s a crankcase split and undo all the top end work I’ve already done.
Seems another unconnected random failure immediately after fixing one thing.
My gp200 was never this much of a ball ache.

Had lammies and they were just money pits. Got an LML and it costs me virtually nothing to keep on the road
