you are correct in what you say...

BTW what would happen if they are not the same but really close

the toro is 17.6 stroke and the fms is 16.8 stroke

So still curious.

Would the Crank from the RB Circuit 9/10/or 11 work.

It sounds like it actually is the FMS crank.

Double Slugged/Silicone Ramped/14.5/same stroke length.

I saw it on amain for 209 (ouch)

it is an on road crank .. i think... who knows... but for 209.. you might as well buy a new engine.. seeing that you like the FMS.. would recommend the X7... i have both... and the X7 is a great engine..

Yeah I like the fms. I seem to drive better with that engine in my buggy than some of the others. It could use a tad more bottom though. I was more curious than anything else as the crank topic had come up at the same time I was tearing my FMS down. I wouldn't rebuild for sure. It not worth the $$

I have my eye on the X7. A friend just got his xtreme version from Monty the other day. I can't wait to see that thing on the track in his buggy.

Has anyone compared (in car) the power between the standard x7 and the extreme. If so how do they differ?
