Do you have any threads right now open for your bike?

Interesting. I wonder why they even made the 58 (if that truly is one of the culprits of my "richness")... I'll look forward to hearing about your upgrades! I need to get some progress photos up here on this thread too. People are going to hate all the dialogue with photos lol >:(

Glad you mentioned this. Daft as it may be to consider if the rest of the engine appears to be in solid shape upon inspection I'm considering improving the performance further such as upgraded cams, bore and what not... Could the large slow jet come in handy if that becomes a reality?

Got it. Will do. Actually, I have valve job, cam timing, plugs, coil test all happening this weekend. I'll make sure those things are in order first prior to finishing the carb stuff. Any other suggested maintenance checks are welcome.... :o

Number on the jet relates to the diameter of the jet right? And the slow jet specifically affects throttle off acceleration? So he buys a MASSIVE slow jet thinking he needs to upgrade it because of the pods and exhaust... see's it's wrong and maxes out the needle to try to compensate instead...

Nice! I'll try it.

By the way how does one clean out the accelerator pump nozzle in #2? Most every other passage I was able to get a super thin copper wire through to ensure it wasn't blocked but the odd position of that has me wondering how to clean it out...

Right now the main jet is a 125 Slow (pilot) is a 58! Needle is set at the highest pin Need to measure the float heights still Pod filters on the bike and a 4 into 1 Kerker exhaust. I have plugs that are wet and black and many signs that seem to point to running rich but what is strange is...

So you guys are saying that my bike has a non-stock set of carbs on it? I'll check the numbers when I get home... Interesting.

Exactly what I was thinking (someone made it). Yeah, I've found the o ringy things which is what comes in most rebuild kits. So I'm sitting here freaking out that I don't have some obscure oem gasket to go back on it. So is it worth me getting those made again or do I just clean those off and...

Small pinhole in the pump rubber where it meets the rod so I can get a new one of those. Just need to figure out where that rubber bellow goes on it. Also, I checked the site you mentioned here and it has the gasket that goes into the bottom of the bowl but still not the one that every one of...

Thank you. On the accelerator pump online they show new ones coming with a rubber bellow. Mine had no such thing on the inside so I have no reference of where one would need to go. Thoughts?

@deviant I attached a photo of the pump from carb 2 below. How do I know if it looks bad? Not sure how you check the performance of that once it's taken apart. @tuneafish Yeah, happy to try whatever combo of positions on the slide needles will work. Really wondering about these gaskets...

Re: New to DTT - '78 CB750 Overhaul (NEED ADVICE!!!) Morning guys, Several folks in my "community" garage had a few opinions on what to look at on my bike but the most common was an improper air/fuel mixture and thus the carbs are off so we can take a look. Photos below show they were very...

Re: New to DTT - '78 CB750 Overhaul (NEED ADVICE!!!) You're right. One of the beautiful things about this is actually that there is so much creative freedom. Being a noob I'll just do my best to make sure my creative expression doesn't result in a creative injury! :o Heading to change oil...
