hello my 1976 moto ski has bin running gret so far this season the in the morning i was guun take it for a spin but it started to miss n stall when i was doing liek 90km and some times not starting n sputtring .. would that be the plugs ?
thanks for the help

The spark plugs would be the logical place to start the diagnosis. When you pull them out look at the condition of them, is one wet and the other dry? Perhaps a compression and spark test while your there?

hey man thatnks alot. but now it will start for a second but it will not stay running what should i do now... it say it has 92 and 89 compression in the 2 cylendors n the plugs are in good shape both wet ? thakns

i'm not sure, but i know on newer sleds 92 and 89 is low for compression, since the two cylinders are close to the same i don't think that this is the problem, but just thought i should give my two cents
