I've been working (slowly) on getting my 1980 650SG running again after many years of neglect. Finally got it started but it doesn't want to rev up. I've cleaned the carbs & replaced all the rubber parts within. Adjusted valves, got a new battery. Sprayed carb cleaner into the cylinders and compression was 117-125, which is not great but should be enough to run OK. Any ideas why it won't rev? I'm a 2-stroke guy so don't know much about 4-strokes. If I put my hand over carb intake on a 2-stroke it has strong suction but there's barely any suction when I put my hand over the XS650 carb. Is this an indication of a problem? I do not have air filters on. Not sure if that makes a difference.
Thanks for any insight!
