dynojet kit

[keith660]

I installed a stage 1 dynojet kit on my 2006 grizz. Stock exhaust and stock air filter, the clip is on the 4th notch from the top, i used the dj 150 jet for elevations under 3000 feet, the mixture screw is set at 2.5 turns. The bike is running great, idles perfect, has good snappy excelleration, but i seem to have lost 3 or 4km per/hour on the top end and it is running lean.(plug tip is whiteish) My question is how should I adjust my carb to improve the richness? turn mixture screw in or out ? Are there other adjustment I should be doing?

Thanks Keith

a main jet size or 2 larger

Adjust up a main size until your top speed doesn't change

Make sure your spark arrestor isn't dirty either

Almost forgot you are going to want to jet when its warm because colder air makes you leaner.

 

[keith660]

do you mean take the dj 150 out and put a larger # in

Yes

I believe I am around 2000ft and I am running the 165 main, can't remember as I rejetted last summer.

With the temps around 3c I am running around 12-13 according to my air/fuel meter.

But once the temps warm up I will be dialing it in better since I installed my wideband a couple months ago
