Hunting Season and HMF Utility pipe

i'd say you should be fine leaving the larger jet size in your carb. i think my stock size was a 162. just carry an extra plug just in case it fouls out. that would be the worst that would happen.

Ok I found a dealer around here that had a quiet core for the HMF so I am going to try that...Did install it and did quiet it down about half...My question now is I have a snorkel 1.5" to 2" and a 165 jet..about 2 5/8 turns on AF screw...still little backfire should I put the 170 jet in...Here is my setup...Honda foreman 500 snorkel with 2 " pipe....165 jet....k/n and HMF utility pipe...My question is guys with snorkel and hmf are running 165 or 170 jets...Most of the people I hear on the forum are running 165....It is hard to keep checking my plug cause it got stripped so I would like to be about 95% sure on the first or second try...Right now it is not running that well...sucking alot of air in the snorkel...Thinking that I need the 170 jet and set the A/f at 2 1/2 turns..thanks for the help

If you want your Foreman to very quiet , get a Benz Silent Exhaust. I'm running one now, extremely quiet , and the little back pressure aids in torque control going down steep hills. I have ran up on deer numerous times on the trials I ride in N. Ga. Not that big of a deal with deer, but also sneek up on turkey. My buddy I ride with also has a 07 Foreman stock exhuast, as queit as the stock foremans are , you can still tell a big different in noise level with the Benz .. No mods needed , slips on the stock exhuast and attaches to the inner frame. Just my 2 cents.
