Topic: DELKEVIC FOUR into ONE EXHAUST ADVICE REQUIRED

[Honda750!!!]

Guys, I am opting for the DELKEVIC FOUR into ONE exhaust set up for a 1972 CB350F that we just picked up. I need some advice on the carburetion side of things, as far as setting up the carburetors to run correctly with this exhaust .............. Any advice much appreciated !!! Thank you, Mark in LAS CRUCES, NEW MEXICO

I would think no jetting required, however, I'm not familiar with the 350 as much.

 I had a 400F that had pod filters and a supertrapp muffler, it wanted some choke to run well. I put the stock intake back on it and that was all it needed. I'd try it and if it has any bog or flat spots try a little choke, if that helps add jet or needle to help that rpm range.

From what I have heard with both 400F and 350F they are bolt on and go... But regardless, if you are going to run them best to get them on and see how it runs before trying to buy jets in advance -- you can always get them later if you think you need to.

Don't re-jet until you get it running and only if you need to

I got the same on my CB350F and did nothing to the carbs,

My totally stock ‘76 cb750F ran very well on stock set up.

Yep, got them on my 75 cb750 as well.

She runs well.
