I have a set of vm's on my 1978 xs650, its been bored 2 over, uni filters, free flowing exhaust. been riding all summer no issues, then a couple weeks ago while i was riding it cut out. While i was in gear and rolling the engine would kind of run at idle speed but when i would open the throttle nothing would happen, and when i pulled in the clutch it would cut out. let it sit for like ten minutes it would start again.When i first put the carbs on my bike i had to raise the needle to get it tuned in, ran fine for months, then this happened. i dropped the needle down to original position, and it was running fine the original issue of why i had to raise the needle wasnt happening, and this flooding of the carbs or whatever it is that cuts of the bike wasnt happening until yesterday. i tried leaning it out some more but it doest run right and i dont want to run it too lean, even if that is even the problem. please help. thanks
