xp 97 won't turn over with new starter after complete rebuild
hi i have a xp 97 with a 787 engine in it and last month i have a total rebuild with the following parts
- new crank
- new wiseco big bore kit
- new starter and new starter relay
- rebuild balancer
- new ground wire
- new battery
when i tried to start it, the starter only gave a loud click. when i turn the motor by hand a little bit it would start. after it's shuts down i have to do the same thing, turn the motor by hand and it starts again.
i already cleaned all connectors and inspect all the wires and took the volt meter true all the wires.
is there something else i could try??????????

Similar thing happened to me when rebuilding a 787 engine a few weeks ago- but my engine was very difficult to turn by hand. (You didn't mention if yours was or not in your post.) The starter would just click and barely turn if at all. I even went as far as to purchase an SBT replacement starter thinking the OEM starter might be losing some torque. Nope. Same problem with new starter.
I finally found that the shaft seal- the one behind the flywheel and magneto cover- was pinched and rubbing against the shaft. (My fault... I had installed it.) The friction alone was enough for the starter(s) not to turn the engine. I had already ruined the new seal so I just put the old one back in. Problem solved.
May or may not be the same problem, but hope yours turns out that that easy to fix.

thanks for the info.
i can turn the engine with 1 finger so that spins fine.
what seal do you mean??? the one of the crankshaft or the one from the starter???

Mine was the seal around the crankshaft. (Dead center behind the flywheel.)

after a few hours of searhing i finnaly found the problem. it was the wire between the carbon brush and the mounting point of the +cable. i think it was broken because of turning the nut to tight to the starter causing the mounting point to turn and snap the cable.
