bigdaddy69 Posted February 20, 2007 Report Share Posted February 20, 2007 When I get my cylenders back from Jeff at FAST I will basically have the same setup as you. I opted to stay with the stock crank though. I do the same type of riding as you, trails and drag. I wanted something that worked well for both. My mods will be 50 over stock stroke, dune/play port with 33 PWK's and pro circuits, K&N's. I'm going to stay with the milled head for now, but when I get the funds I'm going to a cool head. My guess would be 33-35's. Shoot me a PM in a couple weeks if I have it running I'll let you know how my 33's work out. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted February 20, 2007 Report Share Posted February 20, 2007 keihin 33 or 35mm pwk.. id snag whatever ones you can find the best deal on..both will perform well on your 4mm motor.. Quote Link to comment Share on other sites More sharing options...
jbooker82 Posted February 20, 2007 Report Share Posted February 20, 2007 Since you said you ride trails I would go with the pwk 33's. If it was a 100% dune / drag bike then I would go pwk35's carbs. Quote Link to comment Share on other sites More sharing options...

Ducman Posted February 20, 2007 Report Share Posted February 20, 2007 If you have a +5mm rod and run wiseco 795 series pistons (or blaster pistons for big bore) the wrist pin offset is 5mm towards the dome of the piston. This way the total length of the rod + piston is the same as stock. As far as the carbs, might as well get the 34 or 35mm or just stay with the stock carbs. You will be able to get more advice on this forum for tuning the Kehin carbs, but I run the Mikuni Flat Slide TM 34's and I think there a prety easy carb to tune + if you have a large collection of stock main jets they will still work and the jetting #'s are similar to stock carbs.
