I have a 925 RKTek BB for a 2010-2012 AC 800HO. I have run it in my 2012 ProCross 800 with no problems. Dyno sheets from my motor are on Kelseys website. I have sold sled and would trade the 925 even money (you pay shipping) for 800 HO cylinders and exhaust valves. My kit will have exhaust valves, Cylinders, pistons, and billet head. This motor rocks and I have had 0 issues. before anyone asks why I am trading it. It is because I have gotten a new sled every year since 1991 and dont plan on stopping now. If interested PM me.
