i read an article in Snowtech mag which said there were a couple of 2020 models built in Japan. Not sure if they were talking about the RS Venture and the VK series. Does anyone know for sure what models? Maybe they’ll all go back to Japan built for 2021. Nothing like quality built, fit and...

I’m looking into a 2018 Viper and would like to know what the difference/ options the DX has over the base Viper. Thanks

Has anyone modified their 137 Viper /Sidewinder with the Aux fuel tank and trunk found on the 146 ? Is it even possible? I know people will say "just add a Roto-Pak, but I like the fit & finish not to mention the added storage. According to Snowmobile.com the lengths of the 137 & 146 are the...

I’m on the fence on selling my 2013 Apex and going with a 2018 SR Viper. I would appreciate any and all opinions. Advantages/ disadvantages. Thanks

I need help to push me over the fence. I'm looking at replacing my Fox Float 3's with the Assault front shocks for my 13 Apex and would like everyone's opinion. BTW- I have the M20 installed and it's a big difference over the MegaFloat. Just want to make sure the fronts would also make a big...

Does anyone know if there is a aftermarket company that makes a front end widening kit for a 2008 Apex. A friend of mine installed a M20 Airwave and added a WRP seat. I know the seat adds 2 -3" in height and the suspension also makes the sled sit higher. Since the center of gravity is higher it...

I have a 2013 Apex and I would like to install some turnouts for the exhaust. I know Yamaha sells them but those are really just extensions. I would like to know if the "older" turnouts would fit my 2013. If not, what have some of you guys done to make your own? Thanks

I need your assistance. I believe Teamfast built my suspension with the wrong rear shaft and I need the some measurements to prove my point: 1st I need the measurement of the 2 spacers on the rear shaft on the outside of the carriage wheels. They are either both 16mm or the right side is 13mm...

I installed an M20 Airwave in my 2013 Apex 128. I'm trying to align the track and for some reason I can't the alignment even. The left side needs to move to the right and when I tighten the left side it does not move to the right the measurement stays the same, the track gets tighter and the...

Does anyone have any info on installing an Ignition Timing Advance kit?

I'm looking for a shop in the Northeast ( NY, CT, MA, VT or NH) that can install an M20 into my 2013 Apex 128. I've seen the thread posted by NortherSledder and I don't have the tools or skill to manufacture and weld braces. I was able to do the front mounting plates but the rears are a pain...

Has anyone ever had an airspring pop due to ice buildup?

I know there is a thread on putting Mtn skis on an Attak and Favarcat listed part numbers that you will need for the conversion. While looking up the part numbers I notice that the PN for a 2013 Apex spindel and stopper pad were different then for a 2010 Apex Mtn. Has anyone put Mtn skis on a...

I need to replace the battery in my 2012 Apex any suggestions other then the Yuasa YTX14H-BS. Anyone using a Lithium Ion battery? If so, how does it compare to the OEM.

I'm trying to gauge interest on a larger fuel tank for the Apex. Hopefully there will be enough positive responses that we can convince Trail Tank to offer one.

I'm seriously thinking of getting an M20 suspension this summer for my 2013 Apex. I would like your opinion of the M20 and was it an easy install. Any tricks I need to know? Thanks

Looking for some suggestions as to what suspension I should put under my 2013 Apex. Keep the Mono and put in a MegaFloat or Hygear Dual Rate Spring, try a Polaris, or go with an M20 Airwave. Decisions, decisions ......... BTW I have Fox Float 3's in front.
