why wont my power band kick in

[blaster77]

My power band won't kick in I just got my bike running it was the sater key a 89 cent part I kicked it over and it reved real high like it was gonna run out of gas but there was a lot og gas in it it was almost full so a friend of mine that works in a atv shop he told me the main jet is to small so I put a new jet in it my main is 230 but I put a 170 in because the hole in the 170 was bigger than the 230 but after I put it in it idle out good but now my power band is not kicking in why won't it kick in should I put the 230 back because is was that the idleing screw was in to much that why it was reving so high I think my engine is bored 30 over whould that have something to do with it help me any advice

A 170 main is smaller than the factory 230. You are running really lean now. Higher number, more fuel delivered. Lower number, less fuel delivered.

 

[blaster77]

Yeah lean is not good right I'm gonna put that 230 back but the hole in the170 is bigger then the 230 so if I put that 230 back in will the powerband kick in

man i think he gave you a jet for a keihin, there sizes are like that , go back say you need a hex mikuini jet and get a 260 or something

270 if its bored

 

[jeepinncreepin]

if its stock id check your air fuel mixture screw 1 1/2 turns out then mess with your idle screw under your seat.230 is stock definately dont go lower.

 

[244blackblastard]

yeah he mixed up the jets from a keihin/mikuni.

Where is the air/fuel mixture screw? :-[

with the simi right jetting it should run. maybe not the best, but it will run. the a/f screw is for final adjustments. what mods do you have. if its stock a 230 or 240 should work fine. just because you have a fresh bore does not mean you need to go up a jet.

 

[elcolo]

put a 270 jet and check your air fuel mixture screw this screw is out
