I have a 700 ves that smokes lika a locomotive, it is in an 02 blade wx1 but I would think its simply polaris. The cable adjustment is actually on the lean side about an eight to quarter inch. I just bought the sled and havent riden yet , NO SNOW, so I dont know the amount of consuption. Just blasting around the yard it seems to run ok but it smokes pretty good esp. at idle. The previous owner said he ran ski-doo syntethic and that is what is in it now but I will be adding polaris ves2 when it gets low.I cleaned the power valves and they were sooted pretty bad, still smokes. Is there a fail-safe in this system so in case the cable breaks or is unhooked it just dumps oil and it is backed of too far and running on fail-safe or is there an inharent problem in this system??
