I finally bought a jet kit exhaust 9Procircuit) and filter for my 650. For those of you who have already used the Dynojet kit I have a couple questions. Were the recomedations in the directions consistant with the proper jetting? I'm gonna drill some holes in my air box lid, will this make a big change to the jetting? I guess I'm not looking forward to changing out a bunch of jets (twice) to end up at the perfect jetting. Where have others drilled holes in the airbox and how many?

 

I live at about 1500 ft. above sea level and ride up to 3000 ft. I have a HMF, dyno-jet, and twin-air filter. I run the air screw setting's they say and the main jet setting's they say but had to move the needle clip's from the 5th notch to the 4th notch. they were just to rich even with 5 1 inch holes in the lid and the uni vent's if you are close to sea level I would try the 5th notch but that was to rich for where I am.

Could you tell a big diffrence on the combanation that you are running.I have the jet kit and twin airfilter. Im going to buy a pipe have been considering a hmf.

 

All I can say is for the money this combo is great. It will toast a stock 650, and Grizz's on the top end now are no match, just show's how choked down the 650's are stock

 

hey guys ck ebay for pipes i have seen a few there bought an hmf set up for 325.00

 

just show's how choked down the 650's are stock[/i] >>
