anybody????

completely different motor... the C model (and upwards) was actually based on the 98 zx6r motor

what about mounting?? is it the same? what makes the C motor so much better than the B motor?? the head, the bore/stroke, both?? if its just the head, can you bolt it on a B motor?? sorry about all the questions just trying to pick up some info.
thanks Bill

they have completely different bore & stroke.... the C model has a much shorter stroke so it has a pretty wild power band... but theres only about 3-5hp between them stock, if that.

mounting would be fairly different too, as the C model uses the engine as a stressed member where the B model - and ZX7R's - do not.


its definately the B model engines that people put into old ZXR750's.... not sure if they go into ZX7R's easily, perhaps another forum or even google would be of more assistance

they are pretty easy to swap in from what i read. im not sure if i wanna do this swap or just buy a 9R or a 10R. i dont want my insurance to go up to much.
thanks for all the info
