    Carb Tune/Rebuild/Clean........pod jetting?

    I can feel the eye rolls and hear the groans from here haha. Looking for someone to rebuild/clean and re-jet my carbs. I have them disassembled enough to clean. I have the old diaphragms removed as well as the upper portion of the vaccum tubes removed. I have new diaphragms,drain plugs and a rebuild kits coming in. I’m confident in my abilities to rebuild them but jetting them for the pods I have is the troubling part. I also don’t have a sonicleaner and don’t want to invest in one for one set of carbs. If anyone is up to the job and can do it at a reasonable cost and in a reasonable time frame I’d rather use their expertise. The carbs are in fairly good condition and are not gunked up. The floats appear to be in-tact without leaks. Please let me know and I’ll ship them off as soon as I get the parts in! Thanks in advance! 72 CB350 K4.

    Do you want functional carbs, or pretty and functional carbs?
    What's your location?
    What pods and exhausts you have?

    Stock diaphragm carbs will not work with pod filters. Keihin CV carburetors require a balanced and smooth air flow. The airbox provides this. People have been able to make them work by jetting to be slobbering rich. This is a the cost of performance. If you really need to have the pod look you should consider a set of Mikuni carburetors.

    I don't see how someone can tune the carbs without the bike there as well. It's gonna be a trial and error exercise in jetting to get it to run right and even then as Jim pointed out these carbs are not designed to run with pods so....

    I really felt like I was reading Spanish/German there. This is all foreign to me and right now I’m just ready to ride. Do you think the Mikuni carbs will work of present similar issues?

    Do you know anything about those carbs? I’m just trying to figure out why they would work better. I’m also curious about why DCC has them for $300 and, what appears to be, identical carbs are on eBay for $70. Any insight? I keep reading and reading but it seriously just hasn’t clicked for me. Main jets/ secondary/ slow fast.........it’s all complete mystery to me.

    If you want the simplest route, use the stock carbs with the stock air box and filters after you get your carbs cleaned. Buying non factory carbs will take even longer and cause more stress to get running correctly.

    If you are just "ready to ride" as you stated and are unwilling to attempt re-jetting yourself then perhaps you should consider just running the stock carbs with stock air boxes instead. Seriously, nothing you're going to do with these stock carbs is going to beat the performance of the stock air boxes. They were designed and engineered to work together.

    To re-jet and tune the carbs we would need to have access to the bike as well. You'd have to ride it with different jet sizes and adjust to see which would work best. Can't do it with just the carbs.

    Ask yourself this

    Is having that "cool" pod look worth the headaches and aggravation?


    And yeah, there is a reason why you heard a collective sigh and groan regarding this subject LOL
    Many of us have been down this road before and know what a frustrating exercise it is to tune these stock carbs to work with pods. Most of the times, the bike never runs right afterwards with pods.
