Now I can move on and find the max bore size 😉
A recommendation I have received is that the cylinder sleeve needs a min thickness of 2 mm. That would allow to use an oversize piston but only 0,25mm over, to leave the sleeve with 1,75 mm finally!
Pistons are individually made and the cost per piston (incl. rings, bolt, clips) are approx 300,- to 350,- Euros each !
Still working on the “EX-cam used as IN-cam” thing. Will try it but it may be optimised instead of just using stock components (e.g. adjustable camshaft sprocket)
Will keep you updated.
If anyone is interested in participating in this big bore modification plaese let me know. The needed parts and work is cheaper if more than one kit is manufactured.
Cheers, Michael
