Manufacture date 8/08 Fuel pump would not prime after a couple of routine photo ops in Lockhart Basin. Temps in the 100 plus range. Only way to start the bike was push start downhill. Battery and all electronics OK. AM start in cooler temps OK. Thank God. Next day fuel pump stopped working altogether while riding at 35 MPH on Gooseberry Rd on the Fishlake NF. Temps were cool. After towing it for a few miles we were able to push start it on a downhill. Also needed a push start after refueling at Hite, high temps too. At this point I called the ride off and we headed back to Moab. Pump working OK last evening and this am. Waiting for shop to open to replace the pump. Very erratic behavior for the pump. Seems high temps could be an issue. I got to Moab from Denver in cooler temps earlier in the week and had no problems. My son has exact bike set up, same ride, 5/08 build. No problems. Has anyone else had this problem and did replacing the pump fix it?
