the sled started fine and i rode it for probably a good 20 minutes but when i was going close to fully throttle for about 100 yards it completely just shuts off and when i try to start it it feels like it has low compression. After letting it sit for about 5 minutes i pulled on it and it started right up and ran fine but then last night it did the same stalling and has the low compression but this time i cant get it started back up could it be an electrical problem? the low compression has me confused exspecially since it started the first time it did this ANY HELP WOULD BE GREAT HELP and thanks for all the replys in advance

what is the compression?

If it has low compression you will have starting problems, get a tester and see what it is.

sounds to me like you siezed it up and now the rings are beat from sliding across a few gobs of metal....

Did you pull the plugs after it stalled out at full throttle?

If so did they have a gray look to them?

Get a comp. tester and give it a pull. You should get anywhere between 130-160 depending on if something has been changed. I'd say less thatn 120 is bad.

You should pull them and take a look in there with a light to see what the piston tops look like around where the exhaust port is. If it looks gray and funny shaped it is blown up.

You can even just take the head right off. It's an o-ring seal so you won't have to buy anything to put it right back on if there is no funny business. (25ft/lbs head bolts) Open it up and be sure first. Before you look into electrical ghosts.

hit up thumb doc about this one but this seems to be what mine did last year i would not even start it till you pull the head off . thumb doc saved me with this same advice i had a leaking crank seal and siezd it up but not to bad so dont ride it till you know good luck let us know what you find[attachment=41587:snow_08_011.jpg]

Well turns out that with this last snow water got into the air box and then in the carbs so hopefully its just some bad gas but today i did notice that the right side is alot wetter than the left and that plug did burn darker and suggestions on that by chance
