viper

For the first ride of the season I drove 2 hours north last night to go where there is marginal snow at best. Unloaded My 2016 LTX DX with 96 studs and hit the trails this morning and I kept getting stuck, which has never happened on this machine. Also noticed the read end was completely...

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

Researched this topic but did not hear the exact answer I am looking for... I let a guy use my 2015 Viper that has the MPI full kit. Brings it back and it wouldn't start right up to unload, which it always starts up easy. I always let the fuel pump cycle wait a second longer than crank up and...

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...

Have a 2015 viper RTX SE with the upper jackshaft bearings that need changed on secondary clutch and chaincase side. How are people getting the locking collar off and jackshaft out? Is there a special socket or tool? I see a lot of people are putting the 2016 jackshafts in but I’d rather just...

I have the stage 2 MPI full kit for my 2015 MTX. I notice my MPI exhaust is really heavy, wondering if a light weight exhaust replacement like MBRP might be beneficial for weight loss/handling etc. I am wondering if I would lose HP if the MPI exhaust is in tune with the rest of the sled. What...

I put my Viper up for sale last month, and got little to no response. It had 7200kms and a lot of mods. I wanted to either upgrade to a Sidewinder or pay down some dept and get a SW next season. Then one guy wanted to trade a '21 Alpha, basically brand new. I hadn't tested a 2-stroke in the...

Hey, New to this site, and to sledding. I am on my 2nd year of sledding, I know the basics for maintenance and how to handle a 2 stroke sled. With going from that to a 4 stroke sled is there anything I should keep an eye out for? Anything I should do differently if the sled flips other...

Looking for opinions on what a guy should do. Currently have a 15 mtx w/ mpi 190. 162x3” Ice age rails 36” front end And lots of other mods. Is a guy better off looking for a sidewinder opposed to spending much more money on the viper? It’s been a great sled so far. Just looking for other...

Hey guys I was talking to a Yamaha sales rep the other day and i was telling him my plans on buying a turbo viper... He said its not worth it because the 1050cc is apparently not reliable and it wasn't meant to be at the 200-250 hp mark. The guy said I should buy a sidewinder but the price...

High exhaust temps since day one. Right side panel now has a hole in it. Reverse actuator melted stuck. I've added side and rear panel venting, wrapped header from engine to exhaust flange. Today I discovered the wrap was burnt to pieces and the fuel tank had started melting. Exhaust does rumble...

2015 viper MT-X, riding along and hear a pop, sled engine cuts out and slows to a stop. I thought a blew a belt at first but realized no, and the sled was in flames about my oil tank, reverse actuator area. Melted a hole in my plastic and melted all my wires and plug connections on that side. i...

So... Sled was a trade, just got it running with new ECU. Finding lots of gremlins. This scew in particular. Couldnt get a left hand extractor in at proper angle and made it way worse... What do I do, how do I extract this screw without completely drilling off the head? A carbide extractor tip...

Sad Story. Gf's brother smashed my superbuilt P 660 longstroke Rush, New Years Night (not drunk), replaced the frame and he traded me a no start Viper to fix. Story goes, "Viper was running last summer and one day stopped. Replaced the starter, starter solenoid, battery, clutch, fluids, and ran...

Good evening everyone! New to the forum and being a sled owner. Purchased a used Viper a year ago and put about 500 miles on so far. Was riding in the UP a week back and experienced something new. While cruising 60-65 mph, I experienced a power loss like the belt broke. Stopped, pulled the...

I have about 5500km on 129 rtx, the rear suspension seems super soft all a sudden. I have loosened the spring on the front shock in the skid could that be causing the sagging or can it be that the qs3 has failed. My coil spring adjuster at back are 3 (hard) and it seems soft. Sled is gently...

I'm about to order a Skinz seat for my Viper. The Sidewinder seat is for some reason cheaper. Are there any differences to the tank/mounting points on these sleds?

If you guys had to choose between a 14 LTX SE with a MPI trail Turbo or a 15 LTX SE with the full EVO Stg 4 setup with full exhaust, which would you choose? Both have about 5000mi and both have Big Venom clutch kit. 14 Turbo is $1000 more. As a side bar I had a 15 LTX Viper and a 17 LTX Winder.

I run 15psi boost on 93 octane fuel as recommended by mcx, but I recently got my hands on some AVgas 100LL. I decided to go 50/50 with AVgas and 91 octane. What boost can I safely run with this mix, eventually other mixes? I'm guessing all I gotta do is adjust the wastegate actuator.

so snows pretty much gone here in Alberta. have a ton of mods and fixing to do to the sled over the spring-fall. need to get rid of steering slop (replace worn bushings) replace bent spindle change oil/filter chain case oil swap hood, possibly cr racing lightweight hood relocate handlebar...
