nelskin406 Posted September 1, 2006 Report Posted September 1, 2006 just recently put a rebuilt 5mil crank in my buddys banshee, has the wiseco pistons with the different wrist pin location, so as far as I know I do not need a spacer for the jugs, the stock cast head is machined out, I am guessing for a different cumbustion chamber volume. my real question is do I need a different thickness head gasket? I put a stock one in it and it weeps just a little, I did the math and I dont see a issue with interference, and I ran it and it seems ok. or does someone have a sealing trick I need to know about. I also checked the head with a straight edge and it seems to be within .003. thanks for input Quote

Yes, that is the setup, Just curious what was supposed to be the big advantage of this setup, I ran this bike last night, and it has about the same setup as my own, including jetting and aftermarket parts and I was not that impressed. I honestly think my stock crank bike is alot faster or maybe I just dont have it dialed in yet but the jetting seems right on and I have moved the timing around and it responds well to the changes but it doesnt rip the hair from my skull. let me know what you think.

Big Blue Posted September 1, 2006 Report Posted September 1, 2006 better piston angle is the only advantage that I know of. Quote
Bansh-eman Posted September 1, 2006 Report Posted September 1, 2006 better piston angle is the only advantage that I know of. thats all it is. the 795's are stronger then stock pistons. but all he did as spend money on a crank to change the angle of the pistons and rods before it fires. should have got the 4mm stroker while you guys had it apart.

dajogejr Posted September 1, 2006 Report Posted September 1, 2006 the 795's are stronger then stock pistons. Since when? They just have the wrist pin hole moved up for the stroker crowd.... I just got big bore blaster pistons, what everybody used before wiseco made the 795 series..... Yeah, without off setting the crank stroke, you just made it a bit more reliable..that's it. With a longer rod but shorter wrist pin hole to crown height, your port timing should be fine as well... Quote
