Dont know squat about electronics on sleds. I'm like Tom Cruise in Days of Thunder.
Moved a very fine running motor from one chasis to another and now it runs terribly ruff at idle and actually sounds like it's detonating at idle. I pulled the plugs and have freakin smoke coming out of the spark plug holes.
If you swap one cdi box out for another do you have to readjust the timing or is this completely irrelevant?
So here is my situation and here's why I am asking: Bought a sled that was an alphabet soup of stuff. Gen II bulkhead with Edge tunnel and VES 800 motor. The motor is an 800 Polaris VES which I believe to be an 02 or 03. Moved motor into an 04 Escape chasis and used the 04 CDI and wire harness. Started it up and it sounds like chit. I mean real bad.
Trying to give you guys as much detail as possible so here are some other items........I dont know if they are relevant.
1.) the sled had a tether which I disconnected and removed and I reconnected the unplugged stock kill switch. After disconnecting the teather I have a few wires that dont seem to reconnect to anything. The stock kill switch is working.
2.) moving the stock ignition key from PREM to REG seems to slightly impact how the motor is running at idle. Running at REG seems to be a bit smoother at idle. The ignition switch appears fully functional but key handle is broken off.
3.) I bought the 04 chasis used. It had been repoed by a bank so I cant be positive if the CDI has ever been reprogramed. The chasis is in remarkably good condition.
4.) I completely drained the fuel tank and added 3 gallons of fresh gas and even put in 50:1 premix to have plently of lube while the oil made its way through the oil lines. Oil lines not dry just wanted to account for small dry spots.
5.) Carbs are from the 04 Escape and fuel mixture screw and air screw are set at stock. If I recall the fuel screw stock setting is 1.5 turns out and the air screw is .75 turns out but that's just going on memory. Settings correspond to the actual 04 shop manual. TPS is plugged in. I didnt play with the choke or the fuel mixture screw to see if that changed how the sled idled. Main jets are new and are not clogged or fouled in any way. Before starting I gently pulled the recoil about 20 times with spark plugs removed to load some fuel to the carbs. Used a light shot of fogging oil to lube the pistons, cylinders and crank.
6.) initial start up was with no primary clutch and no coolant. Didnt run it for more than 20 seconds.
7.) stock plugs are Champion and I have gone with NGK which is the crossover plug.
8.) motor came with single slp pipes and I'm running slp twin pipes.
9.) compression in both cylinders is 125 lbs each sitting on my garage floor.
ANY IDEAS??
