Here’s what I’ve done: I pulled the carbs, and completely disassembled them (yes even the slow jets), I soaked them in an ultra sonic with heat all day, checked the valves (all in tolerance), changed the oil, new air filter, changed the starter clutch bearing, rewire the whole bike, upgraded the...

I had some gremlins in my stock harness (1980 Cb750f). Now I’m looking to make my own harness, because a tanked the budget. I want to simplify this mess, but I can’t find a simplified diagram. I’ll be running p/a ignition, and cycle x’s charging system. I’ve got those two sorted out, but I’m...

Are there any charging system "upgrades" or cheats for the cb750 dohc? I've seen some ignition switch bypasses, but other than that...... I have replaced the whole shabang this year. R/r battery, stator, and the ignition switch. My fear is I'm already seeing symptoms of a failure. I'm planning...

80 model cb750f super sport, keihin carbs. Quick question: (there seems to be debate within my group of friends) The top puck, with the slide needle,..... is the slide needle supposed to be loose, where you can wiggle it? Or tight, where it doesn't move? They are of the non-adjustable...

Topped off my tire pressure today and hit some turns. The bike did, over all, good. I went from sea level to 4,000 feet with minimal problems (I was expecting problems), and thoroughly enjoyed myself I did get a little bit of an idle issue on the way back home. The idle adjustment screw didn't...

Are the slide needles supposed to be loose, with back and forth play. Like, you can wiggle them. Or are they supposed to be tightened down with no play? I'm having carb issues on a 1980 cb750f, with 83 carbs. I'm thinking alittle grit came out of my gas tank and the pucks aren't sliding well...

I have looked everywhere for this thing, and can't find one anywhere. If anyone has an extra, I'm buying. Needs to fit 1980 cb750f supersport. Are there other available alternatives? Sent from my iPhone using DO THE TON

I recently purchased a 1980 cb750f super sport for a very good price. It started and ran ok for a few days, then as I started tinkering it started running lean. The baffles were rotted out so pulled them, then the exhaust, and then replaced it with 4 into 1 exhaust. I tuned up the carbs and it...

I just moved to Fredericksburg VA. Day 1: unloaded the bike and rejet the carbs. Day 2: gorgeous day for a ride. I took the bike out hoping to maybe meet a few folks, but all I came across were baggers and squid. I would really like to meet some like minded misfits in the area. Some people...
