I have a kit to make your raptor a 686. It is all top of the line stuff, and all BRAND NEW!!

1st I have a JE Piston w/ 102 bore and 11.1 compression. Cometic Gasket kit for new top end. A Stage 2 HotCam, and a set of Kibble White Titanium Valve Springs w/ Exhaust & Intake Spring Seats, and Retainers. The kit is 100% Brand New. This is $475 to buy, Get my set up a lot cheaper, You do not need to Resleve with this kit!

does anyone else have that setup? i was just wondering if it was as good as it sounds i know the craycraft is good, but how much do those cost

 

JE has had some problems with their 102mm pistons, at least in the craycraft machines. Craycraft does the building and the boring and the porting. Thats what makes a craycraft, not necessarily the components because you can buy the same things most builders use from somewhere else.

 

I just put a JE12:1 102mm, stage 2 hot cam, same springs, and gaskets. It went together really easy, everything felt real smoothe. I torqued the head bolts to 32lbs instead of 27 because of the high compression. So far it has been running real good sounds very strong. I have only heat cycled it 4 times and eased through the gears just around the block, nothing above 1/2 throttle. But so far so good, I'm taking it out tomorrow to break it in the rest of the way and finish the final jetting and valve adjustments after that it will be ***** to the wall riding to get readdy for flagstaff on memorial day. then back to the desert racing season. So it will be put to the test for durability and power very soon I will keep it posted.
