My second newb question (many to follow)

[Grahamworks]

More of an advice kind of question:
I am working on a 1970 CB350 K2. The last time she was running, Reagan was president, and the PO left gas in her all that time. ((sigh))

So, obviously I have started with carbs (stock). As I clean them and prepare to rebuild, I've been wondering... Ultimately, I plan on switching out the stock air boxes (which looked like they had something mammalian living inside). I haven't quite decided, pods or KNs or stacks or... But the advice I need is on the jets. I know changing the air intake is gonna require re-jetting. But as I rebuild those carbs, where should I start? As far as jet size? I realize I may need to get a few, maybe even a range of jets. Just curious what my starting point should be when I reassemble the carbs for the first time.

I realize there is some gray area to this question. I have not yet addressed my exhaust, and so forth (assume stock at this point). But I am hoping to benefit from someone's direct experience here and get a starting point. Because I assume stock jets wont be that starting point (right?) When I search for an answer to this question, there is just so much and it doesn't always seem consistent.

Thanks gents,
Chris

Imo, I would start with just getting the bike running. You would then be able to see what else needs to be done. Ie engine troubles or electronic issues. So once again, clean the carbs and worry about rejetting later. My two bits.

Cheers n beers

Thanks. That makes sense. I'm kind of putting the cart before the horse. So I should just put back the stock jets? -or throw in whatever random jet size they threw in the carb rebuild kit? I didn't even look what was in the kit.


Sorry for my dumb question. I have some help locally, but I don't want to abuse it. I am taking this bike one component at a time. A couple weeks ago, I didn't even know what a carb looked like. LOL

Stick with getting the bike to kick over first. If you need jets and if you can't find them around where you live sudco will have the stock jets. Maybe even a rebuild kit too

We always refer to the airboxes on old bikes that have been sitting awhile as the "mouse house". For some reason those little buggers love making nests in there. My friend joked about getting Decon to make poison filled replacement filters.

What everyone is saying is that theres no point in worrying ablout dialing in carbs and jet sizes if the bike isnt a runner to start with. Put the carbs back together in the stock configuration, get some cheapo pods to keep crap out, put the stock exhaust on and get it running. Once you know itll fire, and stay running, you can begin to dial it in. Also, without knowing what your final exhaust will be, there is no way to set up the intake side of things correctly. Everything on a bike has to work in harmony with all other parts of the system to get the optimal performance. Open pipes, baffles, different mufflers, different header lengths, etc. will all have an effect on the intake side of thing. Get her running, and than start making her badass. Youll save a lot of time and frustration that way.

Thanks guys, you set me straight. Gotta go, mine hands were too clean today. Need to get some stuff done.
