its a 94 sl 650 bone stock except extended pump and stuff but the ski will run fine and all a sudden stall out and die then you have to choke it and then it will run fine for a few mins and do the same thing i took the tanks out it had some trash in it i cleaned it out have yet to ride it agin but i dont think that was the causes of the problem since it has a clean fuel filter. it has like 118lbs comprssion on all three cylinders is that ok numbers?
