Inexperienced Sled Owner

Hey, I bought a 98 RMK 700 back in August 2011 and used it this past winter in SW Alaska. I had some low idle issues when I wouild start it to warm it up but didnt think much about it because it ran just fine throughout the winter.

Its getting close to our snow season up here and I want to make sure my machine is running good before the snow falls. I tried starting it today and it took a really long time to actually start and when it finally started it idled decently for a few seconds but then slowly dropped and eventually it died. I would like to be able to go out and start the machine and walk away feeling confident that it will warm up without it shutting off.

I talked to the machanic last year that I bought it from and he didnt think anything was wrong but I cant move past the idea that something might be wrong. I live in a very remote village with extremely limited access to getting parts and something fixed.

I am not an engine person so I would need specific help on what to look for and possibly fix if something needs to be adjusted or replaced. Any help would be beneficial to me, I am heading into Anchorage over thanksgiving so I will be able to look for any parts if necessary.

Brandon

Start by cleaning the carbs. Idle is controlled by the pilot jet circuit. The air and fuel passages to the pilot jet are very small and are easily gummed up as gasoline evaporates from the carb. Keihin carbs are very similar to Mikunis in the way they work, so you can get a rough idea on how to clean them by looking at the "how to" section of the forum. There are several really good posts on the Mikuni round slide carbs.

How fresh is the fuel?

The little fuel that was in it has sat since April. I do not live in AK in the summer but I saw it was low on fuel today so I added some and now it has about a 1/2 tank.

I will go the Carbs route and see if that makes a difference. Thanks!

Fuel (especially the alcohol-laden junk we have down here) goes bad in as little as two months. Carb cleaning is definitely the place to start.
