Questions about 265 BB kit

[CR Swade]

I just picked up a 02 CR w/ the 265cc kit installed on it. Is this a standard kit in terms of the porting specs (are they all the same for that year, or is it custom for each rider?). What type of power characteristics did it produce if in fact a standard kit? Thanks

IF it's one of Eric's kits then the porting is specific to the rider requirments.

Yup, it is one of Eric's kits (unless there is another Eric Gorr out there), according to the previous owner it was for low-end and increased pull throughout RPM. Was installed August of last year and had a power valve/piston clearance problem, so Eric gave him a new piston and cylinder. It also has the FMF SST pipe, I'll know how it runs after picking up the bike next week. Funny thing is the dude can pull outrageous gearing...he is running a 15/50, so the jug must be pumping some ponies out.

FM did the 265 kit and the low/mid porting on my 01 CR250. The result was perma-grin and loads of torque and power on call. I was astounded at the rusults and pitied my pals with thier stock jugs. Unfortunately the frame broke in half a week ago. Maybe the torque was just too much... just kidding...
