727 or 686?
My first question is do you have to do any case mods for a 727? I know that a 686 is a simple bore and hone, but does the 727 have a sleeve? I want some thing to run on the stock carbs and the stage II cam that I have now. The head is going to be ported (not done yet), and what ever set up that I use I want to go with the most compression that I can. I only have a stock bore on 10.75:1 JE. I have been draging in the dunes and that will be 90% of what this bike does. Any suggestions how to make my raptor performance better. I need to fend off those pesky banshees!!!

I would want any engine that can get the RPM's up personally. Thats why i went with the 686 and not something like the Powroll 770. My 686 should be back soon, when its all back together i'll definately post with my thoughts on it. I will be useing the stock carbs. Paying 800 dollars for some new carbs that will only bring another 1.5 to 2 HP isn't on the top of my list. As far as jetting, mikuni jets/neddles. I'll start out at probably 185/190 4clip, 27.5 pilots. I think that should be pretty close to perfect. I sent the head, the cylinder, the top of the head, and the intake boots off to them. G'luck

I would not build a 727. I have yet to see one that was worth the $$ spent to build it. Craycraft is building one monster 727 right now for a forum member that will run a hole in the wind or they will redo it. It has everything in it but it is costing BIG dollars. I am happy with my 67hp little 686. I ordered a cdi box and carbs. You can build a 686 for under 2000 dollars that will take out the corporate 727's.
