ya i think i will just wait and get it jetted other wise i might be throwing alot of money away lol

any one now what size jets i should use?

 

Whats the altitude of where u live???????
what kind of air box and filter are u running?????
what pipe??????

 

well i live in wisconsin no mountins or any thing lol um stock air box with K&N and powerbomb header with R4 slip on

 

K&N jets are the same as Dyno jets i think........start with 170/175 DJ mains, 25 pilots 2.75/3.0 turns on ur air fuel screws.......
give that a run and see what ur plug looks like!!!!!!![img]i/expressions/face-icon-small-smile.gif[/img]

 

ok thanks ill try it out and see what happens im hopin for the best!!


thanks again

 

I'm runnin 170/175 with a full LRD exhaust, Proflow with K&N, and a modified airbox with no lid. Unless you are above 3 or 4k ft, I would say you should be around 180/185 with your 686. The 25 pilot sounds about right, if it pops alot when you chop the throttle after being 3/4-wot, then you should up to a 27.5 pilot.

damn, im running a 175/180 on my stock bore. Hey raptorRacer you didn't happen to change the rod while you were doing that 686 were you? port/polish either?

 

we didnt change the rod and it was port/polished
