Hi guys, I'm hoping not to start a stock vs. Mikuni carb debate, I just would like to clear up some things I've seen mentioned on other threads. My stock carbs are in need of a major cleaning/rebuild, so I was debating just throwing $300 bucks at them for a new set so I can prioritize my time else where. Am I correct in thinking...
-The Mikunis will give slightly higher max speed and MAY have better acceleration.
-The stock carbs are difficult to add pod filters to? Whereas the Mikunis are an easy bolt on?
-Mikunis controlled by actual cables vs. vacuum created by cable movement (is this significant?)
-Keihin carbs slides will still be prone to easy sticking post rebuild?
Thanks for any suggestion or advice you can give....I can take it!
PJ of this parish is the expert on those Keihins, but to try to answer some of your questions.
30mm is rather bike for a stock CB350 and they are NEVER pre-jetted for your bike despite claims to the contrary. If you are lucky they may be close but rarely right. If the motor is breathed on then the change in carbs will probably help at the top end.
CV and slide type carbs are both opened by cables, but the slide on a CV moves with vacuum which makes for much smoother acceleration. ALmost all modern bikes used CV crabs until they were replaced with FI. R1 still uses the same design in its fuel injection, so there's nothing intrinsically wrong with the design - just those carbs which were an early attempt.
I have CV carbs on my drag race GT750 2 stroke and they work well enough to set a national record. Different carbs - same design intent
Those particular carbs do not work well with pods., You are correct. I believe that PJ can modify them though.
I think 28's are the more recommended size. Jetting is still a pain because you need to account for filters and exhaust changes as well as weather and altitude.
Like teazer said, the CV's make for a smoother acceleration and are i my opinion more enjoyable on the street.
