Walleye Posted June 12, 2006 Report Posted June 12, 2006 well, we just got his jugs bored and honed to 65.25mm and installed it, well heres the story, he bought it a month ago or less, and it was in non running condition. got it for a good price, knowing of its condition, being stolen and never run for 1 year. we found the compression out of whack so low, we rebuild the topend. but now when we get it started, keep in mind theres no main switch, no kill switch, no tors, no throttle switch on it, its all bypassed, as it fires it sometimes will idle, sometimes wont. and as we hit the gas it just bogs and sounds like a helicopter, does not rev at all, the rpms seems to like have risen maybe 500rpm thats all. the carbs spit out fresh fuel, (no air box or filter installed for testing) the right cylinder from seat postion is getting good vaccum, than the left one, but the left pipes are much warmer than the right pipes, actually the right pipes arent even warm at all. but the right muffler has better pressure than the left muffler. Plus it kinda sounds like something is gettting thrown around inside somewhere sometimes. We cant actually pinpoint what it is. We re checked all the wirings that the previous owner messed with. everything seems properly bypassed. we even tried fresh fuel, and removed the choke tube, nothing made a difference. heres another thing, the shee came with 2 heads, one stock, one is .020 shaved. both of the right domes have chips like it sucked something in or broke off the sparkplug electrode arm off and smashed it around. we are thinking possiblity bent rod on the right cylinder, or bad crank. other thing is the woodruff key on the crank for the flywheel, its loose a bit and its got some damage on it from the previous owner forcing it in or something, maybe installed it wrong. Could that be a cause? what are the options we have? or does it actually means the crank or rod is damaged? Quote
Walleye Posted June 13, 2006 Author Report Posted June 13, 2006 well now both sides warm up the same and both have same back pressure. were still stuck on whats wrong with it. we accidentally started it with no carbs on and it ran for 5 second and then died. so if it ran without carb and did not rev up widly high, then its got to be the timing is off or the crank or rods are damaged?
