i have 03 raptor 660

if i change (Bore x Stroke) fomm 100 to 102 ? enough ?

is the cams stage 2 enough ? or i need more than that ? and whats the problem i exspect ?

is there any way to beat the banshee on hill climbing????

many question [img]i/expressions/face-icon-small-smile.gif[/img]

sorry for asking .

 

depends on what the banshee has done to it. Just boring it to 102 mm wont do much. You need a cam ported and polished head, bigger valves help also. Then you will probably need a clutch as well. If you want to hang with the banshees that are built for dragging then you wil need alot more than that. If you want to beat banshees you will probably want to call kms up and ask about their turbo and see what they can do for the motor as well.

 

thank you

but there no kms in our country

i think i would change for not draging banshee

*(Bore x Stroke) 102 mm

*hotcams stage 2 withe sprig

but what i fread from :

the heat proplem if i mod my atv ? what you think ?

 

sorry I didn't know where you were from. I will say that a 686 is a good start, and with the proper cam, bigger valves, and good head work that should be all you need to beat a banshee with just bolt ons. but if the banshee has any internal motor work or a good port job then it is all over. The stage 2 is a good cam it works pretty good with the bigger valves and 102mm piston. that is what I have. But right now I am looking into a few cams that are more aggressive. if you go to 102mm then you will want to do some sort of head work.
