Quite reliable, but I wouldn't suggest going all the way to 102mm (686) right away. You can probably just hone and put in a 100mm piston, or if you've got a lot of hours on it you may need to go up to a 100.5mm. Be sure to check your cylinder for clearances before ordering the piston, unles you plan to bore anyway.cams76 said:would this be a pretty reliable setup? good for the dunes? about how much hp am i at with the k&n and full yoshi
The stage 3 is not really designed for a trail motor, and judging from it's similarity to another cam it's best paired with an aggressive port job and/or a large displacement. I'd be afraid that without the porting and fuel to feed it you'll be worse off. If you're building a mild 686 I'd suggest the stg 2 over the stg 3.Mia Ruff-Ryder said:how much does a sleeve cost? and i already purchased my stage 3 or stroker cam. and i was planning on the 686 but am now im curious is there a big power diffence between stage 2 and stage 3 cam??
Let me know how this works out when you do it please, I've already broke the 50rwhp mark and am looking at this as my next mod.cams76 said:if i go with the stock bore but do 11.1 compression and a cam what jetting will i need i just jetted it for the pipe and airfilter
