clutch

I'm looking for a clutch alignment tool for a Viper Sx.

I recently picked up a 2014 137" viper ltx in next to perfect shape physically but with 8500 miles or so on it. First trip it was running right around 9100 rpm at full throttle only on the limiter here and there when spinning. I took out a couple hundred studs and now it revs right up to 9200...

Hi, have a 2011 Nytro XTX and looking to invest in a clutch kit. Sled is fully stock expect a ULTRA Q muffler. Am around 170 pounds & trail ride mainly. Have heard great things about the Schmidt Bros Stage 2 kit that Chris offers, tried to contact Ulmer and no reply. Looking for opinions on...

Friend of mine has a Sidewinder BTX 2018 with 225HP, and some sort of clutch kit. I just put a straight pipe in for the heck of it. Problem is, now it peaks at 10100 RPMs! I'm no good with clutches, so I want a lesson on it. Wondering if I can adjust the secondary spring angle and not touch the...

Just got this Apex (2008). Comparing to other sleds I've owned in the past (although they were much older), it seems like this is not normal. Or is it? Clutch seems to engage on high throttle position. Here's a video: It was sitting in a warm garage so it wasn't bad but seems you need to give...

Hey guys I spun my primary backwards a 1/4 turn while i was tightening it to torque spec. Now I drove it for a mile had a knock sensor light kick on and drove it back home it was running alright, not great. I got to 10 feet away from my garage when it suddenly died. I tried to crank it over but...

Hey! I would like to fix the brutally high RPM engagement on my '16 MTX 141se. It wants to spin track when taking off and is hard to load on trailer. Got some good advice in the Viper forum, but don't think it applies since the original primary spring I pulled out of my MTX turned out to be a...

Hello, brand new to this site and this sled. Bought it last year from an estate sale. Has less than 100 miles on it and is really brand new. The gentleman I bought it from privately had it serviced prior to sale at local dealer ( carbs, ect.) I put new factory plugs in it. Took it up to cabin in...

First ride of the season and my 09 Vector with 13,000 km will only go 75 km/hr. The engine runs fine,starts fine just has no grunt or top end. The throttle is 1/3 open pressing it anymore just does nothing .Does this sound like a clutch problem ? Thanks.

Gone forever

Installed a full hurricane kit on 2008 nytro with just top air box mod rpm’s were almost spot on. I felt it had more to it, as riding with a stock nytro didn't seem to pull any better along with eating fuel. Called hurricane they said I need to give it more air so I did the bottom air box hole...

I'm running TD powertrail, ulmer primary spring, stm weights, stock secondary spring with a 35/39 dalton. I'm not sold on the reverse angle and feel there may be something better out there. In my SRX days we always ran 3 or 4 degrees higher than stock start to 3 or 4 degrees lower on finish. I...

Went to Quebec for probably the last weekend to ride and it started out amazing. Nice and cold, fresh trails from maniwaki to devils mountain and chevel. Next day was taking the local trail to st. Ann du lac when at about 40-60mph heard a loud pop and clutch winding up...thought I just blew my...

Which weights are best to freeride riding? 43 helix should be best, but how about weights? Sled is mcx 190 turbo.

Should the belt still be a 1/16th or so out of the driven clutch with the new roller setup? My belt is flush with the driven sheaves. Thanks
