Cylinder Compression Question
I just bought a 95, 750 V-Twin. 11,461 original miles. No leaks, ran great for a couple weeks. Coming back from a ride I noted a power loss and a little bogging. I've been reading through the forums and have eliminated;
Rectifier & Stator
Plugs & Wires...
I am convinced at this point it is a carb/fuel supply issue (namely to the rear cylinder). But before going all the way and tearing it down (which I know I'm going to anyway, but can't at this time) I did a compression test on each cylinder. Throttle open, wires removed from all four plugs and cranked it over and tested front and rear.
Spec in the book says 122 to 199 psi. I got 110 on both front and back. She still runs fine on the one cylinder (for running one one cylinder) so I don't believe compression is a major player in the problem here and am still leaning towards the carbs. However, my question is - how bad is 110 (particularly since both cylinders read identically)? I'll eventually do the leak-down test, but in your opinions, is it safe to go with the carbs for now and then do what will probably be an overhaul come winter and still put mild commuter miles on it for now? If all were perfect circumstances I'd probably just tear it down, but I need the wheels for a short time longer before I can do that.
Thanks in advance!
