Just did a big upgrade on my '23 MTX and wanted to share. Installed an Alpha 154 x 3" track. Swapped to 3.5" drivers. Installed Syncrodrive with MTX gear ratio. The track has about an inch clearance from the front cooler. I cut the holes using a template and a multi-tool, and reused the...

2023 MTX 153” with 270 kit. After 1200 brutal kms my 3" Powerclaw is ready to be swapped out. I'm posting this poll, but also hoping for lots of feedback on different tracks. Do the paddles flex, does the track trench, is it sturdy, how is the grip, half or full clipped, how much does weight...

People have been asking how to do a headlight delete on a Sidewinder/Viper. Here's how I did mine recently. This one has a 270 kit with cold air intake. It should be possible for stock ones too. I've made a similar solution on a Viper with the same kit. I took the hood off, then...

Anyone who have installed ascender covers on their Sidewinders? I recently had an Alpha and really liked the narrow chassis, great for sidehilling/carving through the snow. I'm considering swapping out the covers, only thing holding me back is the gorgeous look of the Sidewinder.

I'm installing vertical steering on my SW and need a template for cutting the plastics in front of the gas tank. I bought this used and can't find instructions anywhere.

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...

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...

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?

Any opinions on the Composit mountain tracks M66/M67 or M770? I need something as durable as the PowerClaw 3", and preferably 3" lugs.

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...

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.

Viper MTX '16 Mcx270. 4500km. Went out for a ride today, everything seemed fine. Pulled over to talk to someone. After a few minutes I fired it up again and noticed it only got 4psi boost full throttle. It didn't make as much noise. After a while it started improving, but haven't gotten more...

Comes and goes, kills my display too. It started happening after I tipped the sled last week. Haven't found any shorts. Checked every connector except the ones below/behind engine that are hard to reach. I don't have heated shield acc. I suspect oil got into the engine connectors... Ideas?

I'm looking to remove my headlight and use LED bar instead. Is it possible to remove the headlight, then lower the instrument panel? Example:

MCXpress 270 kit installed from shop, got it a year ago. Recently it's been coughing more and more, like I'm feeding it bad fuel. Thinking it's the fuel filter, but I'm not sure. Just did a service on it, changing oil and spark plugs, and nothing improved. It gets better when it's gotten warmer...
