2007 Apex RTX - Need Pre-Maintenance Suggestions

[RayandPaula]

Hi Everyone,
I just joined the forum. Wow, what a great source of information!
I am about to purchase a new 2007 Apex RTX w/ reverse. I have read some issues about engine overheating, hyfax's burning up and drag and resistance on the slides due to Yamaha's improper wheel size. With that being said, I have read some fixes such as;
a) Replace all 6 wheels with larger ones.
b) Install Yamaha's 'Marginal Snow Wheel Kit'
c) Install scrachers.
d) Yamaha's optional rear heat exchanger
e) Drain the cooling system and place Engine ice in it due to Yamaha's 100% antifreeze from the factory.

Are these problems found on the Apex RTX as well? The reason why I ask is due to it's slightly different suspension than other Apex's. If the issue is the same on the Apex RTX, what would you suggest I do in regards to preventing these problems "before they start?" You would think that Yamaha would catch these problems during model testing. It's a shame....... Thanks in advance for all your help! Ray

Ray, please enter your location in your user profile so everyone knows where you are riding.

Regarding your new sled, I'd say ride it first before you do anything. You may not need to touch the wheels. I would change the coolant to a 60/40 mix before investing in a rear heat exchanger.

I'm with Swiss Sledder, I wouldn't change a thing other than the coolant until you ride it.

I've had the marginal wheels on an SRX and had nothing but problems with them. They either froze up and rubbed a flat spot in the wheel, or I lost the whole bracket and wheel altogether. Therefore, I never put them on my Attak and haven't had a problem.

I've never had hyfax wear issues either. I may be in the minoity, but I ride with my hyfax condition in mind. Hyfax melt or wear rapidly due to increase heat. Obviously, they have a melting point and I always try to maintain a temperature below that. What is it? I have no clue, but I temper my time with the flipper wide open and I occassionally brush the side of the trail with my skid to keep things cool.

In other words from the above message, I'd save your money on the oversize wheels, marginal wheels and ice scratchers.

I did add a rear heat exchanger on my Attak because when riding in extremely cold temps, an ice dam can build up in front of the track by the front exchanger; not allowing fresh snow to reach it. I would then overheat. With the rear exchanger, that's no longer an issue.

For what it's worth.....

One thing that I found to eliminate the overheating issue is run studs!! I have 144 1.450 single/double pattern down the middle and I never overheated once. Me and my buddys ran some trails last year that where hard as a rock and my buddy(he rides a REV XP) had to drive really close to me to get any of my kickup to keep his sled from overheating.

make sure to replace the stock bogeys up front every year, they wear rather quickly and from my experience that is where the hyfax wear comes from. I have gotten 2k miles on my sled before they started to wear which was due to the wheels being wore down, as for the over heating i have nearly 5k on my sled and only seen the temp light once and we ride some pretty bare terrain. save the money you don't need it
