Whats going on here? HELP!

[Sx700]

Last month we went to Houghton for our first trip of the year. My buddy just bought a 1996 V-max 600 XT (1200 Mi) and this was his first time riding it, well he got a total of 30 miles in, and had a melt down. Turned out the sled was running lean, melted both pistons. Well last night we finally got snow in chicago, so we went riding...Well my other buddy bought a v-max 600(3500mi) a few weeks ago, and took it out for a spin got about 50 miles in, and the sled started bogging real bad, long story short we lost the clutch side piston. Is there something I don't know about these sleds? Any known problems? I've never had any problems with my 700 SX, and it's got over 5500 miles on it, and never been rebuilt. Any help would be great!

When ever there is a new sled in the group do your homework. Never believe " I never had a problem " Check as much as you can yourself. And always check the plugs for color after the first run of the season. Never know what may be in the airbox or how the storage was completed. Sorry about there bad luck. The best answer is MAINTAINENCE. These are toys that need above average maintainece, a little work up front goes a long way down the trail.

Just a Guess

I'd bet they both had crud in the carbs and got lean, or where jetted on the lean side to begin with. I had a 95 600 and it ran perfectly, and still is. Maxdlx

Well the 1996 that melted was running lean we found varnish in one of the main jets, havent got a chance to pull the other one apart yet. We always do rountine maintenance on the sleds, and then some. Im gonna pull my carbs off and go threw them before the next trip, just to be safe, with all the bad luck.

Somebody forgot to drain the gas and clean the carbs before you took them out. As said above, they're toys and demand alot of attention, especially prior to the first ride. It's easier to clean carbs then it is to replace pistons. Cheaper too.
