    I'll likely get a set of vm29 smoothbores for the Rickman CR900 894cc GS build as well, unless I decide to do a GS1000+1100G top end + 1146 pistons... then I may be looking at VM33 smoothbores or possibly 85-86 Canadian gsxr "vm29ss" which are nothing at all like the vm29a smoothbores. More rare, in fact. Non-USA direct linkage competition model flatslide smoothbores that are actually a rack of TM33 dirtbike carbs with a 29mm throat bolted to the front, more in common with the next carb in the lineup, the RS34.


    I'm really ting to keep it all mikuni here, and mostly all VM stuff that uses similar parts. Instead of getting some gs650 CV carbs for the wife's gs550+650 top end, I discovered that the gs650 head has a 28mm intake port, and that I actually unknowingly had a set of 28.7mm KZ1000 VM28SS carbs and that they seem to be able to bolt directly to the GS550 VM22 rack with the vm22 fuel rail couplers, throttle shaft, choke shaft, and the only fab work being a new lower return spring mount, as the 22 uses a pin set into the carb bodies that no other 26mm+ vm's have.

    I think I am even going to go as far as to make my own custom rack, shaft, and fuel tee to make a 2 cylinder set of VM29 smoothbores for my GS425-475cc racer build. This has been done before. A local machinist guy here did the same thing for a 500cc Yamaha twin that he used to race.

    Thanks for all the support everyone. I'll let you know how this one fares.
