250R hybrid (pilot cylinder)
I just recently came across a set of cases that have been machined to accept a pilot cylinder, I also have the cylinder its on it 1st bore size of 80mm. I have a 7mm crank w/ a yz 490 rod
I know packard racing has built these.
Anyone ever have one or see one run??
I was also wondering about the pistons I see some people have put up to a 91mm piston in them I was thinking of goin w/ a 86mm, Just dont knw what pistons there using.
Any help would be greatly appreciated. Thanks
