Hi,
I can't find anything anywhere for slip-on or full exhaust for 650H1 ATV's....or jet kits. Who has modded there H1 and what did you do to it? Where did you get the goods?

 

HMF has slip-on exaust. mine is too loud and the pipe they sent with it (quiet core) insert simply restricts the air flow and not that much quietier. Made my own, about 11 in. long that diverts sound waves, but lets the air move freely thru the exaust.

There's a few different jet kits out. Even the Harley tuners have the Keihen carb jets. Cost three or 4 dollars each for pilot and main jet..

 

I'm at sea level......what elevation are you and what jets did you use? Is there a way to unrestrict the stock can? Anybody think clutch kits worth the money??

 

I;m in n.e. arkansas. I think about 400 ft above s.l. easy to get more air. add more inlet tubes to airbox. Someboby did it and worked well..

Clutch kit , many have done it and seems to help quite a bit. I haven't done mine, YET.. Lots of topics on both here. just gotta find them.

where are you at sea level?

 

Ontario, Canada.......Does anybody use this site???? Clutch Kits anybody??

 

under advance search, type in clutch mods. many people use epi & dalton clutch kits. also you can post a topic under "other topics" instead of a/c and get alot more replies.

Many people read & answer questions on here. More so around the weekend I think.

Go to www.highlifter.com I think the HMF will fit your 650 we put one on our 400 and it has the same line up holes.

I'm wondering. can someone tell me what slipon exhaust is better than stock but not louder?
don't need the noise, just the power.
