Hi i am new to the forum and the motorcycle world, just got my cb350f last year and finished the conversion to a cafe, the only problem is that ever since i have owned it when i get on the throttle it will bog down , so say im in 1st gear and i just go to WOT it will bog down slowly build rpm then when it hits a certain rpm it will just open up and rip but its very inconvient and hard to ride like this i have gone through the carb at least 5 times and cleaned them. Any help would be greatly appreciated
 
More info necessary: what's yer exhaust, stock 4-4? Aftermarket 4-1? Baffled or free flowing? What's yer air intake? Stock airbox? Pods? If so, what type? When you rebuilt carbs, did you rejet because of any of the aforementioned? Did you replace jets?

You've got a carburetor problem, but knowing the other stuff will help diagnose.
 
Okay bike has a 4 into 1 exhaust that it came with, also i a running k and n pods have not rejeted yet. What jet size do i need ? and is that the problem because it did this with the stock air box
 
How did you clean the carbs?? and what jets are in it now??
Did it have pods on it when you got it??
 
Let me ask you this just to get it out of the way: do you have a manual? Have you tried to adjust your mixture settings? Changing the exhaust or the air filters changes the fuel mixture. Sometimes you can get away with playing with the mixture and not rejetting, depending on the set up. Have you pulled your plugs and looked at them? Plugs will tell you a lot as to how your bike is running (rich or lean).

I should add: most manuals have a page that shows common problems as diagnosed by looking at the plugs.
