Hey guys i have a quick question. i have 2007 100% completley stock yfz. I ordered the HMF sport series exhaust for it. what jets will i have to use if its just the slip on im adding. Also can someone give me a link of a site that i can order exactly what i need?

thanks kevin

Is that a slip-on, or full exhaust?

And, the jet's you can get at your local dealer, they should carry a large variety of jets.

You should be able to get all your questions answered on the HMF web site, and might be able to order the jets there also.

are you doing anything to increase your airflow? still stock filter with airbox lid on?

Im taking the bike in to get its first service to make sure everything broke in right, if i bring them the slip on pipe do they usually have the jets i need right at the place?

call HMF ask what to run and I would get a K&N while your at it so you won't have to re-jet again. HMF will tell you what to run then order it from either your local dealer or rockymountainatv.com

HMFs suggestions are pretty close... well, at least for where i ride (Glamis).

for the slip on at sea level, i would imagine you would be around a 170 main, with either a stock or a 45 pilot. of course, thats assuming you put a K&N and take off the air box lid

alright ill probably get the K&N will im at it. i ride in rhode island, dont know if that matters. The places that i ride are sand/dirt/a little muddy/ should i still take the air lid off if im riding in this?
