Hi Gang,
I have a 93 NH750. The number two cylinder is not working, but the compression is 85. I completely cleaned the carbs. Full tear down, carbs separated and cleaned with new jets installed. Brand new plugs. Swapped plug wires. Nothing worked. Compression in 1,3 & 4 is 60. I am pretty bummed here.
Any thoughts on the dead cylinder? Also, with compression down on 1,3 & 4, what needs to be done? Is this a big job?
I appreciate any input!
Thanks All.
Guys............Im an idiot! I did not warm up the bike, so my numbers are off. I will have to wait until tomorrow to try again. Can I expect a big jump in compression? Still does not explain dead #2 cylinder. Thoughts on that?
