Stomp77 Posted January 28, 2005 Report Posted January 28, 2005 I have two 34mm constant velocity carbs off of a 250 ninja. they are vacuum operated and use the diaphram fuel delivery system. Mechanically they appear to work perfectly on the banshee. They mount up, fit well and have manually adjustable choke and throttle settings. Which means that the carbs are eniterly mechanical in nature no computer required. I am rebulding my banshee engine, when i am done i want to use these kehin carbs instead of my stock banshee crap.If i do my jetting right which means a ton of plug chops i think it should work. Iin theory the amount of fuel provided by cfm will be controlled by the jetting in the carbs, while the ninja carbs do have a coaster enrichment system which affects the idle mixture.it should be ok, cause, Under load the coaster enrichment system is bypassed by the primary pilot system the coaster enrichment system works to keep the amount of fuel coming into the motor always the same whethere under load (take off) or idle at a stop. The carbs have a pilot and mains system very similar to the banshee's so as far as i can tell this Should actually work very well. I see aftermarket flat slide carbs for banshee's on ebay all the time. What is the difference? beats me, The way these ninja carbs work is awesome tho, i really want to get them to work. whats the worst thing that could happen? shee would not run or start or idle is my theory as long as i check my plugs constantly (if it runs!) has this ever been done before? am i risking dire consequenses? have street bike carbs been grafted to banshee's before with great success or major failure? i am curious and would like to hear some horror stories or even some successfull stories. I will upload pics of my progress thus far sometime in the middle of this weekend's bender probably at 4:20 am on saturday thanks for any and all opinions Quote

I think you will find that the needle will most likely be way to rich or lean for the shee, actually probably all the jetting. The question is can you find a needle, pilot and main to make your shee run right? Are they readily availabe to order for those carbs in the size you need, which you don't know yet. If yes, then I suppose it may work as long as they will fit a typical 34mm intake manifold boot and the carbs are not too big on the bowl dimension to clear the clutch arm. Quote

Stomp77 Posted February 2, 2005 Author Report Posted February 2, 2005 Cool, my pics turned out bad but, according to this http://jimrace.com/faq/CVK40.html (carb function diagram) everything is proceeding according to plan. If this works right... then, Quote
