We sunk a rx-1 once. Tip it on end to drain the exhaust, pull the plugs,change the oil and away you go. Sounded like hell when we first fired it up but its still livin to this day. It was an excellent sled for waterskipping but we never tried anything like this guy, nutso.

Some yammi tech said once that the phazer motor barely passed yamahas strict standards in the vibration and harmonics department. maybe there is no future in that 500cc twin. True story? Who knows but thats what this thread is all about isnt it.

I agree, if loud pipes are risking your access dont run em. BUT dont jump on every guy on here who wants to run a loud exhaust, There isnt a trail system or snowmobile club within a couple hundred miles of me. Wouldnt want to ride a trail anyway. :bore:

Sounds like alot if inconsistency with the MBRP pipe. Mine was fairly loud when new and got louder after a season on it. At WOT its as loud as any MBRP(race version) canned two stroke.

This happened to mine once. Cold day, everything was iced up. Thawed it out in the shop and it was all good. Not much help i know. It would be sweet if that fixed everything that goes wrong with it.

First off, I know that these clutches are normally noisy. This is different. Its a loud ticking, from idle right up to full throttle. I pulled it off, had a good look at it and I cant see anything wrong. buttons look good, no flat spots on the rollers, weights have play in them but nothin...

Are your timbersled rails stock length? I was running a 156 with the stock rails and the stock rear wheels. The tensioners were maxed but it didnt ratchet. I have a freedom axle with 9" wheels now and i have lots oF adjustment.

I have a 156x2.5 with no mods, stock wheels and skid. I have the track tension adjusters all the way out and the track is a bit loose but does not ratchet.

I have the MBRP as well, I wouldnt say it gave the sled a hesitation but the throttle response is definetly worse. Im gonna mess with the CO levels to try and cure it. Sounds good, probably too loud for you trail riders though.

From what Iv been told, the only difference is the 2.5 lug. But now i see that you can get a 153x2.25 Extreme on camoplasts website, so I dont know.

Stock wheels are 7" I believe. As far as I know thats the only mods to make it fit. Will know for sure next week when I install it. 156x15x2.5 Challenger Extreme-$770 153x15x2.25 Challenger- $740 or something like that from Tracks Canada I went 156 cause you cant get a 153 with a 2.5...

im going 156 with 9" wheels only. Other guys have done it with 8's

Has Yamaha acknowledged this problem? Whats to say that the new replacement subframes coming from Yamaha wont just bend again?

took this off Snowest ok this is top secret!! in your nose cone area you will find a single wire in a white connector.. remove connector and ground wire, then turn on key and depress both buttons on dash. navagate through menu till CO appears then chose cylinder 1,2, or 3. change setting to...

A guy on snowest said he cured the stutter by adjusting the CO level. This was with a slip on muffler. Ill be installing my MBRP next week, hope it runs right

$250? looks like $309 to me. Price went up maybe? How about a sound clip! ;)!

My Maverick started to shred after 300 kms, missing about 10 lugs and the outer layer is peeling off. 156 Challenger Extreme is on the way.
