Makes sense, Although should turning on high beams activate the rear running light? Currently it doesn't so I went back to the PO did for now. Although I would like to have this fixed properly. I also seem to have a strange issue of my guage lights activating and blinking with my signal lights...

Problem solved with the headlight

ahh no idea that was the case Thanks!

Deleted problem solved

Hey Everyone, I swapped out my wiring harness today for a new one from vintagecb750.com While doing this I noticed that there was an additional wire running from the rear brown connector all the way up to the headlight and plugged into the black that would normally power the signal buzzer (its...

Accel pump 100% works on all 4. I am able to squirt fuel right out the front of the carbs when I have it out of the bike. I have heard people have some luck with the older carbs without the Accel pump. If they raise the needle. Would that actually help or just cause other issues if I shimmed...

Ah my bad #35. Finally received new coils and now all 4 cylinders are working. So far this is the happiest i've seen the bike I had to adjust my mixture screws with the additional cylinder burning gas every stroke instead of every few. I was able to get reasonable throttle response out...

Ahh shoot my bad went back to size 35. Anyways went back to the 40. I cut the ends of the wire and recrimped, still had the same issue. so I swapped the ignition coils. And then the same issue appeared on 1 or 4 with the 1/4 spark plug wires attached. depending on which wire was attached. so...

Found something interesting today. I switched the ignition cables between #2 and #3 and now #3 is the one not firing correctly. these are brand new coils and cables. does it make sense something is up with the cable as the coil still fires one of them fine? There is spark from both. I will...

Is there a possibility of a bad pilot jet? I'm using #40 I purchased off cb750supply. I've probably cleaned these 12 times trying to figure out what's going on. I have them on my bench right now and air blows through all jets easily

Yes it will respond, Nothing wrong with the colortune it just made the issue more obvious I'm using Magna dual output coils with whatever wire they come with Dynatek ignition NGKD8EA plugs and boots The color tune works great on all other cylinders it just made it very obvious to me that #2...

Sorry, wrote things down wrong everything is around 135 psi +/-5 psi Even if I did have a pump that wasn't accurate if there was a compression issue on just #2 wouldn't it be getting a much different reading than the other 3?

Yes all cylinders were within 5 psi of spec

Yeah Ideally I would like to get to that point, But I need to figure out why cyl #2 isnt igniting consistently below 2000RPM first. I realized I've checked all valve spacing apart from #2 intake as I cant get it with a socket and a the crescent wrench seemed like it wanted to strip it. (17mm...

I'm still learning tons so by no means am I even close to an expert so I may have done a few things wrong. Originally the bike was barely running and had to idle at 2500 RPM. So every time I've tried a new potential fix for its many symptoms its seemed to get better and better. I believe I saw...
