    Hi I have a 99 mountain Max I don’t think it matters but the engine is a 96. I was wondering I only have about 87 psi per cylinder is it time for some rings or do I have to dig it out and go bigger or what size bigger rings would I need the sled has no top end left feels like 440 not 600

    I am in search of either a whole stator assembly or just a lighting stator for a 76 exciter 440. It seems parts availability does not exist for this sled.

    Hello everyone, I posted a while ago asking about a dg exhaust, because they were noticeably cheaper than other brands, and everyone said that they suck. So with that information, I started looking for better pipes, and a buddy approached me with one for 20$, so I took it. Not too bad of shape...

    I just bought a Yamaha Vmaxx 600 XT. The guy I bought it from said I should mix the oil 50:1. I eyeballed the mixture into the tank. I drove it around for a while and then I realized the “oil level” light was on. I popped the hood and found there is an oil tank which is empty. Do I fill this...

    Is it possible to remove/ bypass the battery, rectifier and starter relay for this sled? The rectifier prongs are broke off and I can not find one to replace it. Everywhere I look says they're unavailable. I'm guessing this is the reason I don't have any spark.

    I blew a ski by hitting a rock going 120 in a field. I no longer have a left front ski and the right has some pretty gaping holes in it. I've been searching the web a bit lately but can't seem to find any skis/carbides/runners for that sled or any that say that they will fit that sled. I don't...

    I’m working on an 03 mountain max, hasn’t been run in a few years, got the carbs cleaned up, replaced plugs and I’ve got good fuel in there. I’ve checked spark and I’ve got heet in the tank to account for any bad gas or water still in the lines. It starts up easy but won’t run smooth, it doesn’t...

    Hello I have a 1991 Phazer and it used to run great then one day it stopped running.. found no spark so I changed the plugs, coil, and cdi unit and it had great spark! It started great but ran really touchy and cut out every once in awhile and didn’t like mid throttle and only started after a...

    I have a '99 Vmax 500 deluxe that I'm kind of bored with. I want it to be more capable, but without spending $800+ on a 121 to 136 extension. What popped this idea into my head was when I got an offer for a venture, same year, but obviously with the 136. Originally I planned on using it on my...

    A buddy of mine has the same 1999 Vmax 600 twin that I do, but his will lift the front end a foot or so off the ground when he dumps the throttle, but mine won't. We have the same 1 1/4 inch track, but mine is studded, so shouldn't it be easier for my sled? In a straight drag race the sleds are...

    I have a 1999 Vmax 600 twin. It starts every time 1-2 pulls and runs great. It'll rip like a brand new sled for the first 30 minutes of riding. After that, I notice some power loss, maybe 10-15% less. Around 10-20 minutes later, it won't rev about 6k, and takes up to 20-30 seconds just to get to...

    Just bought my first sled yesterday, it’s a 95 vmax 600 double. It’s got 3000 miles on it. How are the oil injection systems on them? Should I pre mix it or not?

    i have an 84 excel 340. it runs perfectly when i’m not moving it around or lifting it, but when i lift either end of the sled it will bog out and die. same thing when i start to move and turn. i just went through the carbs, new plugs, good compression. i don’t know what to do.

    I recently picked up a 95 VMAX 500. When I got it the taillight worked but dash/headlights did not. I bought a replacement regulator and put it in, now the taillights won’t work either. Put the old one back in, still nothing. the harness into the regulator isn’t going in all the way so it...

    I have a 1988 Phazer and I have a 1976 GP440 engine which I’m trying to put in the phazer. The problem is that the engine bay has a big brace in the way of the fan on the 440 so I’m wondering if its worth cutting the bracing out and welding my own bracing around the 440. If you have any...

    Okay folks to start off here is what I have done. Cleaned carbs, all new fuel lines and related. Fuel pump works great, lots of pressure at both outlets. Secondary rebuilt, primary is new. Deflection is set properly and using proper belt. Machine seems to be governed at 5000 rpm as per the...

    Got 2 SS440’s that have been sitting for a few years cleaned the gas tank, carb and put in new fuel line. I got the thing started and once I turn the choke off it idles up to about 3000rpm then bogs our and dies. I’ve tried adjusting the idle screw but it does nothing. When the choke is on I can...

    What's up guys? I'm new to the page. I'm looking to add an ice fishing sled to my collection that still has some speed and would make a good backup or loaner sled for buddies to use when we go out on the trails. I'm looking at 2 different sleds and would like your opinions on both. First, there...
