What's everyone doing to their 137s for radar run set ups? Transfer blocks out and limiters pulled up? If so, how many holes from stock? Blocks in? Center shock adjustment? Lowering front end (by loosening front shock springs). I'd still like to get a little transfer for drag racing. BTW...tuned...

Has anyone measured similar studs (example: INS Hornet 1.64 vs Woodys Trigger 1.63) against different brands? Hornet 1.64 is supposed to be an overall length of 1.95 inches and the Trigger 1.63 is supposed to be an overall length of 2.024. I'm not sure if the different manufactures measure...

For those of you that installed LED handguards, where did you tap into power?

Does anyone know of a good quality replacement bearing for the newer (2018) tri-hub? OEM bearing number is 3604-033 (this is Cat's number).

Whats everyone seeing for operating temps? Anyone know what thermostat is in these sleds?

Hey Guys, Curious if anyone has any experience with this helmet. I'm thinking of purchasing one with 509 Sinister goggles. This will be my first experience with an MX style helmet. Any input is appreciated. Thanks~

I happen to have a set of 2006 Apex handlebars (with grips). Has anyone tried using these on an FX Nytro to get the super hot grips that works when you use them on a 2007 or new Apex? If so, any issues with the CPU?

Just picked up my new Curve skis from Sean at the Syracuse show. Like many of you, I've gone back and forth on what skis to buy. Razors, XTs, Yamaha Mountain, etc. To be honest, I really wasn't looking into the Curves until I ran into Sean at the Ohio, NY grass drags. He explained a couple...

I'm just curious if anyone has tried the 8BU-00 clutch weights in a Nytro. The profile seems pretty agressive, yet maintains good force throughout the stroke. Plus, they're very close in base weight as the stock (8GL-00)weight. 48.7g vs 49.43g respectively.

Does anyone know what the stock (from the factory) compression and rebound settings are on the 2009 Nytro RTX SE? This would be for both front and rear shocks. Thanks~

Guys, Has anyone tried a 51/43 (stock Apex) helix on the 121 FX Nytro?

Hey Guys, Anybody try the Fix clutch kit? They use the stock gearing and stock helix. However, there's a roller change, shims, weights, springs, etc. Apparently they went 107mph in 600 feet. The only thing that concerns me is that they run the RPMs at 9500+. I don't know how this would be on...

Hey Guys. As many out there, I'm thinking of switching from my 06 Apex RTX to a Nytro. The RTX SE model to be specific. I've read so many issues with bent subframes, weak A arms, blown belts, error codes, wet feet, etc. Can anyone set my mind at ease? What problems (if any) have any of you SE...

Hey Guys. I'm deciding on making my RTX a 136. I know the Attaks are close to or equal to the top speed of stock Apexes. My question is, for those of you that have converted a 121 to a 136, have you lost any top end speed? In theory, you should. However, we all love to prove theories wrong. Any...

I just put a new belt on my 06 RTX and its squeeling like a pig. I heard that my sled comes with 1mm washers on the back side of the secondary. I'm going to try the 0.5mm washers to get rid of the noise. My question is, can too tight of a deflection cause a drop in peak RPMs?

Right now my 06 RTX (with Ulmer Stage 2, 40 tooth bottom, EK plugs and air box mod) is shifting at 10,700 then dropping to 10,200 and pulling back up to 10,600. I'd like to pull up to 10,800. Right now the secondary spring (silver) is wound to only 6-2. My question is should I wind it to 6-3 or...

Has anyone tried the Ulmer Stage 2 kit while (at the same time) overdriving the primary? This is assuming that there is a gearing change as well.

Does anyone know if you wind the Yamaha grey secondary spring to 6-2, will you get coil bind?

For the guys out there that are running a speed sheave, I'm just curious what helix (angle) you're using.

Hey guys ~ I'm new to the four stroke thing. I bought a new RTX at the end of this year and put 160 miles on it. My questions is, should I change the oil and filter now, change it in the fall, or leave it alone until I hit the intial 500 mile mark?
