Hi all, new here and this looks like the place to find answers to get my bike up an running. I just picked up a 1980 CB750F and the guy said it ran good last year but he tried to get it running this spring and had no luck, so it has sat until now, I have been able to get it to fire up and run, anything above 1,100 or so Rpms it runs good and smooth, but lower then that rpm it'll backfire some and try to die, I can restart it but it won't stay running at idle. From what I know about dirtbikes that means the idle jets are plugged and needs cleaned. But this bike has 4 carbs but I bet it's the same. Also it has the stock air box removed and it has the little pod style filters. Any ideas from anyone? If I can get this problem fixed it'll be a cheap toy as I got it for $100.
Thanks
