HMF slip-on results [Archive]

I finished installing my HMF slip-on today and ground down the header while I was at it. Well it fired right up and the pipe sounds pretty mean. It's got a deep tone to it. The pipe is kind of loud, but it is not obnixous. I like the sound and the look of this pipe. It installed real easy and I didn't have any problems. I took my 400 for a little spin and you can really feel the added power. The throttle response is awesome and the low end is much stronger. I was going to go with a 14 tooth cs sprocket but it would be too much low end. I'm going to hit the trails with it this weekend and will let you potential pipe buyers know what I think. I still have to add the 4 WB air vents he gave me so that should help some too. If you're looking for a pipe I would recommend the HMF because you can't beat their prices and they offer different colors. So far so good.

what main jet, piolt jet, and needle clip did you use? Was it easy to instal and what all did you do to grind down your header? Is it necessary to do this?

The only thing that I changed on the carb was the main jet and the air screw position. I went to a 165 main and 3 turns out on the air screw. Installation was a breeze, the thing that took a little while was the header removal which isn't necessary but I wanted to do it while the silencer was already off. If I didn't do the header it would have been a 15 minute job.

I just noticed that you have the HMF in your mods list. Don't you already have it?

Yeah I have it , but have yet to install it. I bought the bike from a friend and he had the pipe but never got to instal it. Gonna be going for our first ride of the year this weekend.

It's a deep tone. Depends on your neihbors. It shouldn't piss anyone off unless they hate atvs. Oh yeah HMF told me their pipes came in at 98 db witout the quiet core insert. That's pretty good. The tone sounds really mean, I love it. You'll see!

Mine is polished because I got a deal on the one he had there. I originally went in there wanting the red, but the polished looks real good. They all look good it just comes down to your preference.

I heard earlier that the HMF slip on doesn't fit over stock head pipe because it has a bigger diameter. Is that true?

BlueOval 400:
I thougt the same thing when I first got mine, but I found out that it is just a very snug fit. I had to spread the tabs on the slip-on where the slits are just a little bit to get the slip-on started onto the stock headpipe. You do not use a exhaust gasket like the stock exhaust uses. It is just a metal to metal joint which is clamped on with there supplied clamp.

Mine went on perfectly. Didn't have to do anything to it to make it fit.

I was planning on getting either an LRD or big gun pipe but now you've got me thinking about an HMF. You mentioned that it increases bottom end power but how does it do in the mid range and top end. DO you think a 16 tooth sprocket would even it out nicely.:D

Yella, why are you selling your HMF didn't you like it? I think the slip-on kicks ***** and couldn't see parting with it. Oh well your choice.

What about buying the quiet core? It sounds like your neighbors won't be happy with any pipe you buy! Are you going back to stock?

03-18-2002, 09:15 AM
