ok i have a 2001 wolverine k&n air filter , cobra exhaust, 6 uni vents
my question is i cant remember what the position was for the needle in the slide 2nd slot or 3rd
and whats the idle mixture screw to be set at 2 turns out or what


help

 

main jet 147.5
pilot jet 50
stock needle - stock position
fuel screw - 2 turns

forget the rest of it.

 

I've got mine set up almost identical to Wolverinerider and we have similar setups...147.5 main jet, stock needle position (mine was 3rd groove from the top, I made a note of it). I tried lowering my needle clip to the 4th groove from the top and mine was way too rich. I still have the stock pilot jet, but I'm going to try going 1 bigger. I have to run my pilot screw out approx. 4 turns, which is probably a bit much.

Adjust on the pilot screw till it feels good from the 0 - 1/4 throttle transition.

I would suspect your setup should be somewhere close, depending on altitude, temp, etc. Put in a clean plug and do the "throttle chop" plug checks to make sure you are not too lean! Being Rich was pretty obvious for me, a lean condition was harder for me to tell.

If you're unsure about the plug checks, do a search. There is some really good info on here if you have the time to dig through the search hits.

 

IIRC- the stock wolverine needle setting is smack dab in the middle

With your mods, you will need to jump up the main jet for sure and possibly raise the needle some [img]i/expressions/face-icon-small-wink.gif[/img] It takes a while to tune your carb, but once you do......... play time
