Since it doesn't seem that the weather is going to ever act like winter, I'm thinking it is about time knock the dust off of my summer toys. Toward the end of the season, the Jammer had a couple hick ups. Once in awhile on the later half of a long ride the ski would start to bog down at wide open throttle. If I released the throttle for a split second and then pinned it again the power would return and I could continue riding with any trouble. A couple of times the bog actually led to the ski to stalling. This was not a frequent occurrence but it did happen a couple times. I plan to rebuild the carb and replace the fuel pump diagram. I was also thinking maybe the thermo switch was starting fail. I did remove the hood after it stalled to check the engine was not overheating The motor seemed to be running at a normal temperature. I was just wondering if anyone has had a similar experience with the old Yamaha 500 Waverunners or Jammers. If anyone has any tricks up there sleeves I'd love to here them! Thanks!
