I was hoping that there might be somebody out there that could help me?
I have a 98 Powder Special 600 EFI. I rode it for a half hour after buying it before it started to develop a miss and backfire. It got progressively worse to the point that it will start for a few seconds and quit. Give it any throttle and it backfires and quits.
I've swapped coils with a buddy and it was the same. I bypassed the throttle position override by unplugging the wires coming from the throttle and heat shrinking a tube over the middle prong. I had my stator rewound out of desperation.
Now I have the throttle body disassembled, everything looks alright.
The only thing I may have overlooked is the throttle position sensor? I pulled it off the throttle body but I don't know of any way to test it?
Whats next? The ECU? Hope not, a new one is almost worth as much as the machine!
Has anybody else out there run into similar troubles with an EFI machine?
Any help would be greatly appreciated!
