Alright just so everyone know I did research and I still have some outstanding questions. I ride at around 500-600 feet above sea level, I have a Raptor 660, and I thinking about modifying it. If I was to buy a HMF full system, and a pro design intake kit, what jetting settings would you guys say I should use. (dynojet) I was thinking maybe 160-165 and then clip on the 3rd on the needle, 3 turns out, and I don't know about the pilot jet. Tell me if you guys think this would work or be too rich. I know what jets are and how they work but I don't know how to make combos with them.

Thanks,

MIke.

 

The Hmf is very nice.

 

Im not a jetting guru but i think for that dynojet would recommend 148 and 150..

 

Iuse a full HMF with K&N's and I use 160. The HMF will come with instructions and settings.Youll love it, major HP increase and LOUD too

 

This might help? I have an HMF slip on and a pro flo K&N open air box. if your not doing any porting "or engine work" save the $$ and go with the slip on. I ride at 2000 and I had to run 180/185 "not dyno jets"with the needles on 5 "all the way up" leave the pilot alone A/F 2 1/2 on the left and 3 1/2 on the right. It's a little fat but it screams dragracing. If your airbox is open I would try this combo cause if it's a little fat at 2000 it might be right on at 600. Good luck!!

 

hey i have an hmf and an edelbrock carb i really like it

 

I would love to go to a single carb, two carbs "twice as much work!!" whats the price on one of those $700 to $800????

 

check parts direct i got mine for about 590 but that is with a twist throttle the thumb version is only 519 i think
if you call them the prices are higher than the internet
