Just thought I would share a possible 40hp lead I regrettably had forgotten about until the other day. It may just be a load of
, I know I kinda thought it at the time and did not think much about it but thought Id share anyways just incase this turns out to be the holy grail of wr250r/x modification. And would love any input especially from anyone thats heard/looked into this at all?
I was talking to a gentlemen around august of last year in either in the parts or service dept. at this local shop called Procaliber. We were talking about my wr and he mentioned someone he met/knew had dumped a bit of money into it and was able to get a shop to install a "450" topend on their wr250.
The pro caliber guy seemed to know a little bit about it and the gist of what he told me was that the WRR motor either had much more in common or was even based on the YFZ 450 quad motor rather than the yz/wr450 motor.
From the little research Ive just begun to do it looks like the yfz motor has a similar look and the stator cover looks the same. It has a different crank and bearings than the YZ motor. From what I've read the YFZ has a much sturdier transmission and has also been detuned for reliability reasons.
