I had a look the other day while swapping gears and all is well with the 4206 bearing and 2016 jackshaft in my 2015 Viper. That's over 2,000 miles this season so far.

I'm wondering if anyone is running the Dalton QAY-54 weights and if so, how much total weight they're using and what mods they have done. Trying to decide if I should get those or the QAY-58 in order to get the ability to pass the 61.4g total mark if I needed to. Anyone have a PCV or flash...

My 15 Viper RTX now has around 300 miles on the SKF 4206 bearing with the updated 2016 shaft. So far, so good. Nice clean fit and relatively cheap if you just buy the shaft, not the assembly with clutch side bearing and holder. Sent from my LG-H873 using Tapatalk

I got just under 15 today, but I was hauling #*$&@!!!

My sled had the rev limiter adjusted from Yamaha's race team. It was a X-country race sled initially. When it was being raced, it had no reverse and 22/48 gears. I was told it did 105 MPH pretty reliably... I have made some minor changes to the clutch set-up to make it a little more trail...

I managed to pull 98 MPH with the 21/49 gears and it gets there very quickly. I'm kinda ok with that... because I'm out of money.

After review, it does look wrong... too much adjuster angle. I put the stock gears back in. 21/49

Can I get away with running 21/48 gears with a 90 link chain, or will it be too long? Thanks

Great point, I'll check availability on that one too. Thanks

I looked at a 2017 sidewinder today (pretty sure its the same as the 2017-18 Viper case) and the 6206 bearing is seated fully into the case and the circlip groove is 4mm deeper than the 14-16 viper groove. I think a 4mm spacer would work fine so you could use the 2017 shaft and 6206 bearing...

There is no inner case number per se'... Its an assembly with bearings already installed, and as such has different part numbers. Without seeing one up close there's no way to know how they account for the narrower bearing.

Specs look good for the 4206... Static, dynamic and fatigue load limits all exceed the 6206. Reference and limiting speed are a bit lower, but still within tolerances for this application.

I know, but I'm saying the shaft dimensions for the 16 wobble bearing (2206) are the same as the (4206) bearing... 20mm. So no need to worry about spacers to locate the shaft or bearing within the chain case. Although I see what you mean about the clutch side locating the shaft... the chaincase...

nope... the 6206 is 16mm wide all the way http://www.skf.com/group/products/bearings-units-housings/ball-bearings/deep-groove-ball-bearings/deep-groove-ball-bearings/index.html?designation=6206 I think I'll follow Janne339 and use the 4206. It is the correct dimensions for the 2016 shaft and...
