What's up with these carbs?


Recommended Posts

I picked up these Banshees last week and am waiting for all my parts to come in the mail. In the meantime I'm working on non-engine stuff.

 

So I pulled these carbs and I am wondering about them.

 

The new ones: are these cheap Chinese carbs? Are they any good? These are budget builds, but I'm not willing to put these on of they are junk.

 

The Keihin's: I've heard this is a good brand but I do not believe these belong to this model quad. Both have a choke, which is weird how would that even work? They came off of the running quad so they obviously worked, but are they ideal? Are they better than stock? Should I just get stockers and replace them?

 

The made in Japan (MIC) ones: I believe these are stock, correct me if I am wrong. But these actually appear to belong to the Banshee.

 

One more question: is TORS already deleted on all of these? I don't see the TORS delete screw anywhere on any of them. They both also had just regular screw caps.

 

Thanks in Advance!4fd0dcf65137fe07f686529f497cd273.jpg90a893148a582fac1f18a7c7833d97d7.jpgc3b3196461f98c791f2a705818d6682d.jpg6ca845099406799fc3724f40d965a18a.jpgbf619889744bfcb0355bf54dfe46110b.jpgacac7eff278b6a0cc2d408582af90992.jpg2d5256538eb3c9b2000b6b12c8f2a2a4.jpg02509682a4d9920c588fc57b01bd9b13.jpg6a7a970e6a1b852942bdec3d3e0f7955.jpg

The new ones appear to be knock off Mikuni carbs.  Possibly both for the same side as both are missing the choke plunger? Could be shit, could be good. Most people avoid knock off carbs.

The Sudco/Keihin carbs appear to be either a 36 Quad vent, or 35 or 38 AirStriker. Probably a little overkill for a stock setup.  The chokes works by pulling the choke on both carbs. ie the choke is activated on each carb independently of the other.  Most people run the Keihin PWK series if running a modified engine.  I can't tell, but if there isn't a part number stamped below the PWK these may be fake as well

The real Mikuni carbs are OEM for the bike and it appears that 1 of them is missing the idle screw. and both are missing the caps. I can't tell, but the bowl on one might be missing something or is broken off. You can possibly replace the bowl with one from the fake carbs.

the keihin's are PWK cars, so they are a good style carb,  we just need to know the size of the bore where it goes into the boot for the reeds.  That way we can tell if over kill.   When using a PWK you only really need to choke one side to get it fired up.  I have 28mm pwk's on my quad and love them compared to the stockers.  Plus no worrying about a choke tube, if the bowl is on the right carb etc.
