Did'nt Butch say that the 749R had shorter barrels?

The 57mm system will physically fit no problem, external differnces on the motors are so negligable that it will make no difference.

But unless you have the R variant of the 749 then the best performance gains are from the 54mm. it gives just about the same top end but the peak power is lower, so easier to get to and use.

Good luck and fit a PC3 or you'll have plenty of fuelling issues.
