Yo bros... anybody knows the R/S ratio (rod/stroke ratio) of our D17A2?? I nid the conrod length to calculate the ratio... where can i lay my hands on them??

I m juz curious to find our hw well our D17 revs, cos the closer the ratio is to 1.75, the better the rev-ibility...

Thanks for the information...

I don't think it's good, our stroke is bigger than the bor I believe.

Its easy. *pulls out book of useless equations and other random bs* All you need to know is the length of your stroke and the length of your rod from the center of both ends. Divide the length of the rod from c to c by the length of your actual stroke. An ideal r/s ratio would be as closet to 1.75:1 as possible. Don't put too much weight on r/s ratio though. You don't need a great r/s ratio to make a nice screamer. Piston speed is something you'd need to be more concerned with.

haha do all D17 stuff except D15 crank. haha 6.28:1 comp ratio. that would be terrible

but you would get a 1.62 r/s ratio. lol thats funny though.
