jmkapala Posted March 31, 2007 Report Share Posted March 31, 2007 my bike was doing something similar. i had a VERY weak spark the only time i could see it was in a dark garage. I took the wiring harness off, shortened it, pulled off all the butt connectors that the yahoo before me had on there, made sure all the connections were soldered good, and taped it up. BEAUTIFUL spark now. from expierence, will knock the s#$t out of ya. IMO its in the wiring like the above posts said Jim Quote Link to comment Share on other sites More sharing options...
Olds Eddie Posted April 26, 2007 Author Report Share Posted April 26, 2007 I like my crow with a little salt and Heinz 57. I decided to do a compression test on this 'just rebuilt top end' moter and It explained everything. 60 PSI just wont run. The guy that did the work is a very experienced motorcycle mechanic that I have known for years so I took it for granted that it couldn't be the top end. This shee ran outrageous the day I took her apart to do the wiring. It had not been more than a half dozen laps around the house with cool downs between runs to break in the new top end. He says the rings could be stuck. I'll know soon enough as I am going to pull the cylinders off asap. Quote Link to comment Share on other sites More sharing options...
shee rips Posted April 27, 2007 Report Share Posted April 27, 2007 (edited) 60 psi on both cylinders? some thing is definitely wrong in the top end. 60 psi in both cylinders would most likely not run even if everything else was perfect edit - head gasket???? if its a brand new top endand both cylinders are the same compression that would be my guess, but what do i know just my .02 Edited April 27, 2007 by shee rips Quote Link to comment Share on other sites More sharing options...
