Nice unbiased review. Reviews from guys coming off other brands, guys who ride hard and ride for fun are better than a hundred magazine articles. Rad screen looks real sano. ;)!

Reply To Valve Cover Fix

Update on valve cover issue, I dropped the sled off at the Dealer and they replaced the valve cover and put a protective hose on the coolant tube if it rubs on the cover in the future. That coolant tube does need to be secured to the frame by the bleeder port on top of oil canister though. I must say again I am very pleased with Yamaha and my Dealer with the issues that they are taking care of with no grief to me, no cost to me thank you very much.

Wow! you weren't kidding about the valve cover. What a rub. I'll be checking mine soon. Can't wait to see the R&D photo's. Are you going to have the Lite up and running by the weekend? there is a chance I'll be coming back up if the storm tomorrow night pans out.
 
Off Season R&D Project

R&D Project

Well I thought the season was over but mother nature decided to dump 40" of late season snow on us. So the off season project had to be speeded up and completed so I could test it. Took the sled out yestersay and loaded up the footrails and watched them melt down, to bad it wasn't colder and more powder for testing conditions. Those footrails with heat exchangers under them sure get hot, I will be posting pictures and putting some miles on this weekend to fully see the results.
 
Can't wait for the results on the heat under the floor boards.
 
Update On R&D Project

Update On R&D Project


I had the Phazer out this weekend to test out the heated footrails and I must say it was worth the work. let me start off with I wish the conditions were colder but you gotta work with what you got. I rode in 18" of wet snow and put a 100 miles on the unit, it was nice that there was no snow on the rails.

One of the test was taking and packing snow on the rail up to the top off the tunnel with just enough room for my feet to fit. This is about 10 Lbs. of snow per side and after 8 miles of riding it was all melted. I was riding with a friend and he thought it was a bit funny that after 8 miles the snow was melted completely off.

We rode in alot of unridden trails with tons of snow spray and I must say that no build up was great. My feet were a bit toasty so the mickey mouse boots must go. Update on install to follow soon.
 
What if you hit rocks/terrain with the running boards? Won't that bash the heat exchangers and dump coolant?
 
These heat exchangers that I used are very rugged like those on an older Indy 500, plus they start in the middle of the track approach. The start of the exchanger is under the lower side panels so if you hit something you will have to rip that off first. The bottom of these exchangers are very thick, they are not thin like the 120HP or 150HP Yamaha sleds. They are tapperd at the front of them also, I will posting my pictures and info on the install soon.
 
Heat Exchanger Installation

As I stated in the review I love this sled so this project was worth it. When riding with a friend in deep powder that has a RS Rage it occured to me that his footrails are always clean. So the brain started working and the project had to be done.

I looked at a Rs Rage and thought that would be way to much work to route it around the tunnel. So I was browsing Ebay and saw left and right side footrail heat exchangers from a 2003 Polaris XC 800. They had in and out ports at the front and I was the only bidder shipped to the door for $29.99 excellent.

A bit off cutting took place to get them to fit the short footrails and the delta box portion of the frame. The existing support piece had to come out, took em in to be welded up and mounted them on. Piped under the engine in front of the oil drain plug and back behind the starter with aluminum tube. Made the final connections with coolant hose and anchored as needed.

It was a bit more complex at times but it was nice to see it finished. On the original test ride I noticed the heat exchangers were warm but could be warmer and that was at 45 degrees. So I removed the radiator and fan yes thats right, and went and tested again about 20 miles and no overheating. After the ride at operating temprature I let it idle in the garage for 13 minutes before it shut itself off.

The final test came on Saturday at 45 degrees in wet snow for 70 miles and no matter what I did it would not overheat. If it wont overheat with these condions it will be just fine any other time. Here are the pictures for any interested in tackling the project. Total cost to do the job was $200.00, it took more time than money.
