Fancy a triple cylinder engine for a year round daily driver? https://www.toyota.com/upcoming-vehicles/grcorolla/

Who is interested in a 4 Stroke SX Viper? Well then, you have come to the right place! I recently picked up a 2002 SX Viper ER, and while the triple 2 stroke is a neat engine, I have not owned a 2 stroke sled since roughly 2006, it was quickly realized that I do not miss the exhaust.... or the...

No, this is not a pun, it has nothing to do with Ski Doo. I have a chance to purchase what is essentially a nearly unused 2005 RS series sled w/ 37 miles on it. From what I gather, it has been reasonably well stored and the mileage is genuine... But that remains to be seen. I am aware of most of...

Here's s little brain storming idea that has been in my head for a bit now. Through another project, I found that parts from an EPS Grizzly could possibly make a nice swap into a Nytro chassis. The EPS motor assembly is the exact same unit/part number that is used on the Apex and Vector EPS...

Did you really think I had reached the top of the food chain with the 50mm shock? :Rockon:

I finally built a 50mm piston equipped Monoshock. The capacity and strength of this unit are increased in just about every way. The piston grows from 46mm to 50mm, note the larger body. The larger piston can create more force with less effort/work. The reservoir grows is diameter from 49mm to a...

I happened upon an RS Viking H-L-R chain case for a good deal, and since I've always been curious about it, it was purchased. I've been brain storming what to use it for, and if it does not wind up in my 2014 Yamaha Viking UTV/side x side project, it could find a home in an Apex (if it is...

I placed a deposit on Seth's Race sled this week. Plans right now include riding and building shocks in an attempt to produce what this could have been from the beginning, a great all around high performance trail sled. If things work well, and it won't be stepping on toes, I'll look into...

Yamaha occasionally publishes technical papers for some of their products. These are all of the snow machine papers I could find, some are better than others. Get out the translator. I'm unsure if these have been posted in the past, if so, disregard. 2011 Apex...

A base model LTX.... I'll build some Ohlins for it (I have not forgotten you, Don). Now, will I have time to ride it?

I figured there are enough posts asking about these, with much speculation for and against the design, that it is well time someone ponied up and gave them a test run. The order has been placed. The Nytro spindles are scheduled to be machined the week of the 23rd. So hopefully they will be in...

It's time for the A-arms on my sled to move beyond plain bearings. The order of the day is needle bearings rotating on case hardened shafts, sealed with X-ring and maintained with zerk grease fittings. I built some needle bearing arms for my ATV. It was suffereing from the same sloppy quick...

This is the front lower a-arm eye mount from my 05 Rage. As many know, this is a common breakage point on the Deltabox. The hit that broke this wasn't terribly hard, quite light in fact. I never really examined where it fractured, but today I had a look. Here's a nice picture, no leading...

Here's a look at the air spring concept Ohlins developed. I believe this prototype was built a few years back. Little information exists about it, but it is safe to say it won't see production. Still neat stuff, though! Enjoy. :Rockon:

As many know, and many more will evenutally find out, the plastic steering bearings that Yamaha uses are problematic. When the grease wears or washes away, the plastic wears quickly, which leads to sloppy steering in short order. While there are some VERY nice solutions from the aftermarket...

Skis have to be one of the most discussed items on here... heavy steering, darting ect. A couple years back someone mentioned using the skis from a VK Pro. They are wide like the mountain skis, but don't have the curved edges down the sides. The other large difference I noticed with the VK ski...

After hunting around a bit, I turned up some bolts from ARP that might do the job. They produce a bolt from 8740 that is rated for 170,000 PSI, which is in the Grade 12 range. The stock bolt is a Grade 10 130,000 PSI. I'll report back with more info when they arrive.

Here's the latest project idea, getting my 2009 Nytro FX to corner REALLY well while keeping the great bump performance. IMO, once set up, it does an admirable job in corners given the weight of that beautiful chunk of aluminum and steel under the hood. The formula so far includes the typical...

These work well on some of my other toys... Why not on a sled?
