All depends weather effects alot biggest thing to look at, is your plug color . If its runnig good the color will be a tan colored plug and go fom there, black to rich and white to lean .

Our water cooled DRX 90 come with a 107 jet we are in Florida and the bike would hardly run put a 100 jet ran better but still spits and sputters finally went with a 95 and bike runs strong no problems guys at East Coast Performance helped me good guys
Try the 95 you will be pleasantly surprized

miniquad, what air filter are you running,i run in the stock class and all i can do is take the dust cover off but it works fine on the drx 50 we run.your not the first to tell me to go down in jetting.doesnt seem right but i will try it.

Running stock airfilter and oil injection still hooked up bike is 100% stock right out of the crate bike would hardly run with jet it came with

both mine run but not very well on the top end, still breaking them in with the oil they came with,they are just loaded up with oil i think. Tonight i plan to use pre mix and play with the jets when they come in.

thanks,

when jetting keep in mind most quads will be shipped in a rich condition , it is safer ,
So usually jetting down will improve performance unless you have made other mods .

Was that with the mud cover on the air filter?



You also have to get past that break in oil to get it to run well...

Did you get the blue one or the black one?

We got oopen them up a little last night and they both are running great out of the box. all we did was take the dust cover off and pre-mixed one of them. these WC are some very fast quads cant wait to get some of the up grades bulldogfallon has told me about.

thanks for the info on the jets they got here today will try them tonight.
