i made my own can out of a glass pack and i put it on and now when i go to ride it today i got on and hit the gas and it was like i was pulling the brake it wouldnt take off unless i got off and pushed it and when my dad picked the back end up i hit the gas and the track spun fine but with the stock can on i had it idling at 1,500 RPM's and with my new can it droped the RPM's to 1,000. its like its not gettin enough gas but it is cause when i get it to go it gose like a bat out of hell so can anyone help.
Thanks. here are some pix and a video.

yea it sounds like your clutch has somthing to do with the issue. Thats what my mxz sounds like but i have it set up so it kicks in at 5200 do you have a clutch kit on that? Did you look at your plugs and see how they look? is your spring broke in the clutch?
(edit) i was gust thinking you might not be geting enuff back preasure with that can!

if there is a clutch kit its probaly set up with the stock can and changeing it could effect it, try putting the stock one on and see what it does Quote originally posted by santo5

lol taking off your belt to rev the sled is a very bad idea there is no load on teh engine so what happens? you let off throttle your gettin proper amount of air and fuel for idle but your engine is still spinning at 3-4000 rpm. an easy way to toast an piston.

Not true. My buddy went through 4 different cans on his M1000 before finding one that worked. One of them wouldn't even let the sled pull itself out of the trailer. You probably have too much back pressure if it's a glaspac. Try something that's open, like a cherry bomb or something. What happens when you take the can completely off?
Just curious, why are you trying this. Alot of exhaust manufacturers put alot of hours in R&D and Flow Bench checks not to mention DYNO time trying to get just the right back pressure and performance. For instance, S&S makes a can that fits an Edge RMK that they designed to work with the SLP single pipe. The S&S can works with the SLP single WAY better than the SLP can.
Don't get me wrong, nothing like trial and error to learn a thing or 2.

uhm yes it is ture, 98% of back presure comes form the pipes the can gives to 2% of it, the reason he was haveing that problem is becuase some cans need jetting and/or clutching. al tho it is farily rare. if hes rideing an M1000 id say hes rideing up high where altiude is also a factor in this..

viper man try the damn thing with yur stock can, it only takes 5 minutes to un hook some springs and rehook them, you could have done it 20 times in the time that u have been wathcing ppl make guesses, help us elimanate things to narrow it down, Sorry for the spaz dude, just try it out

Easiest method of troubleshooting, work backwards till it works again.
If all you changed is the can, put your old one back on and check to see if it works again.
If it still doesn't work normally you have more work to do.
In general I don't think many of the cans on the market improve the sled, and I feel a number of them are detrimental.
Oh and don't lift the rear of a sled and rev it either. Put it on a stand good thread about a guy losing a leg to that exact thing, you risk getting hit by studs, rocks, ice, bits of track, or even the whole track.

NO! the can has alot to do with backpressure. That combined with the outlet diameter and length of the expansion chamber determines the pressure.

Thats exactly what they are. They don't know what they're talking about.
That glasspack has way too large of an inside diameter. When you say it feels like its starving for fuel, thats because IT IS! It's flowing more air=lean. Put the stock one back on, or jet way up and get crap for power and mileage.

dont ever and i mean EVER rev a sled motor without the belt on. you probably just messed up your primary clutch doing that. it engages at 3500 to 4000 and you had it to 5000 guess what the clutch sheeves just did? SLAMMED together. you did more damage with that video clip then good

My bad on the glaspac, I thought they were the more retrictive type. However, a can has ALOT to do with back pressure. It is what causes the pipe to work correctly. And yes, you are right, this is amplified at altitude. We're talking close to 8K when the M1K wouldn't move. I've seen a difference of probably 10 HP in different cans on my buddy's M1000. Beleive it or not, I've seen it. The stock can is one of the best, but it is tooooo heavy.

I was going to say make sure the engine is warm enough so you dont have to choke it before you rev the hell out of it. but what do i know.lol
like squidward said. try lifting the needles one clip or raising the pilot one jet size.
nothing goes like 3 holes!!

Most glasspacks have a smaller tube inside that has raised openings to allow the sound to be trapped or changed, cherrybombs are usually more open like a tube with the holes in it. Glasspacks will usually create more back pressure and turbulance than say a turbo type muffler, that is why they say to use a turbo of some sort for power, instead of glasspacks. My .02

I think you should put the stock can back on. It sounds horrid and obnoxious.
