This a great sled for people who knows how to ride and can handle the power
.
I had issues with mine but now I have taken care of the probs that really was no biggies.
-One thing to look into when buying is see to that it has 07-mapping.
That will prevent for those plug issue they had earlier and increase performance.
-Increase your idle to 2-2200rpm:s, this will also prevent it from fouling plug.
The only time these days I've got plug issues is when starting my sled and without letting it warm up properly put in reverse or shut it off and start it up again.
It's a little bit sensitive to this but when knowing about it, no problem.
-See that your e-rave cables are properly adjusted.
-Get a clutch kit like the one DJ sells
www.mxzx-revzone.com , helps keep your clutches cooler that will make belts last longer and really makes your sled come alive.
-Make sure when your closing left sidehood that it are properly closed so no beltdust or other obsticles can get in there ruin your engine and clog up your reeds.
Many puts some prefilter, made by some fine mesh, on the inner airbox to prevent this.
I myself have seen to that is properly sealed between outer and inner a-box when closing sidehood.
-Learn how to tune your clutches, because there's a lot of RAW power that wants to get to the ground.
-Remove the plastic, if it's not done, from "aluminium clutch cover", this cover will just make your clutches to warm.
-If it's the original battery, change it out.
A bad battery does strange things this to this sled like e-raves not function properly, hand and thumbwarmer stop working and other electrical probs.
I changed my original 3 amp batt to a 14Ah and those electrical gremlins poof, went away.
There are much things to do to make this great sled even better but learn after time.
There's some "break in period" for the DRIVER on some 100 miles or so to learn how to control this raw power heavy weight champion.
-One thing that helps with this weight thing everyones nagging about is get some wider skis.
Many on this kind of sled forums seem to like simmons gen2.
I widened my 05 original crappy skis inwards to keep it easy to lay down and handle in the deep pow and when sidehilling.
This is heavier than those smallblocks like 800 and requires a different way of riding.
You have to work WITH it and find the sleds balance, not wrestle it, because IT WILL turn out winner
What sled have you rode before?
