when you jeted you bike did you have to mess with the idle jets? what did you have to do?


Thank

JETS??? DO you need a FAA license to have that?? J/K!!!
If your bike is running poorly at low RPM..then yes..
When you buy a jet kit which is normally $120 or so..you are not really buying the parts. What you are paying for a the PROPER parts and research time.
The parts alone ar probally only $30 per carb ( with the needles, clips, jets, ect...)

 

Directions with kit will let you know what to do with the idle jets. Normally they are not replaceable -- only adjustable via a teeny screw that's a pain to get to.

 

well I was running like SH*T on the lower end but when i put the stock needles with the Jets it fix it right up....... Im going to call Erion Racing to find out why that could be. when i put them in i fallow the manual on how to install them to the T but the needles seem to let too much gas in at lower rpms but the stock needledont. I will be messing with it the next coupld of days. The next thing i have to fig out is y my throttle is sticking and why it is backfireing.


Thanks for the input

What carbs are you running? The last carbed bike I jetted had mikunis (sp?) and the low range (idle to 2500 rpm) was controlled by the idle circuit. After that the needle and replacement jets took over. Mine ran like **** also because I had the stoopid idea that I had to use the BIG jets. Once I realized the skinnier needle worked better with the smaller jets, my bike ran great. I ended up with a smaller jet than stock -- the needle is the thing -- smaller lets more gas flow with smaller jet = great mixing of gas and air.

My hunch is you're probably running very rich off idle. A lot of trial and error to get it just right. When you get it close, have it dyno'd with an air/fuel meter to make sure you don't hole a piston by being too lean.

 

the stock F2 carbs. dont know what they are....
