i have aquired a genuine 64mm sr kit,what piston is recomended for this considering i am going to run a 22 jetex and original under kickstart fresco?
i also need this to be a low compression motor so need ahead to go with it or who do i use to reprofile a 150 one .
thanks in advance

Hi, Mark. I ran a Deanspeed one when my SR barrel was first taken out to 64 but the rings wore the bore out really quickly. After MB tuned the barrel, I ran a Racetour 65mm for something like 7 or 8000 miles without any problems. MB matched the head to the piston. As far as I know the Racetour is still in the engine.
My underkick fresco was well suited to the tune and the TM24 Mikuni
And what project is this for, mate?

suzi piston kits from Beedies only 39 quid. Quality rings and 4 oversizes .. but I'm sure you know this already. The 2nd incarnation of the enduro racer used this set up with a 25mm phbl and under kickstart fresco, ran great.

Cheers ian but I don't want to top and tail or redox my crank so as I said I want to keep it simple and plug and play
