enjoy your lunch....thats one pricey dinner plate....
I did the same thing to the viper before I put the rebuild back in her last month.
9200 miles ....center crank bearing went south....good to go, now
Skidoo riders- help me out
Success! :thumbup: Well, partial success. It did light up, and I had it running for at least a minute or so. The recoil is kinda screwed up so I have to fiddle with that, and I'm not sure why it quit after running for a minute- but I know it runs now.
The problem was: the ignition pickup coil/trigger was mounted in the wrong spot in the stator housing. Indeed the ignition was firing at the wrong time- way after TDC. On the RER (Rotax Electronic Reverse) models a secondary pickup coil is mounted in the housing maybe 30 degrees of crankshaft rotation later than the forward coil. Obviously when the operator wants to go in reverse, the MPEM disregards the signal from the primary pickup and uses the signal from the secondary pickup to initiate running the motor backwards- a pretty genius design save for the fact that you can mount the coils ambidexterously. I'd go so far as to guess that the pickup coils are identical (ease and low cost of manufacturing) and that they simply are mounted in different spots. They should mark which spot is which in the case, thereby nincompoop-proofing them.
05Firecat (& RedBaron) had the right idea (which was my original suspicion/feeling the first time I tried to run this thing), but because there is no real provision for actual ADJUSTMENT I'm only gonna buy em a pop- no lunch.

You dont owe me anything...Just glad that you could get it running/figured out.

soda?
Hey, where's my lunch? A soda sounds fine, I will have it mixed with a bit of Korbel Brandy at Johnnies. A good time to pay up would be this weekend at the 100 miler brushing day! I am glad to see another skidoo come back to life, hope you can sell it soon.
