A while back I bought a CT110 Carb from DRATV to put on my ST90 after I installed the big bore kit and performance camshaft also from DRATV. I quickly found out that the boot that goes from the airbox to the carb would not fit on the new larger carb. I emailed DRATV about this and here is our exchange.
-Me: Hello. I am going to install your big bore kit and high performance camshaft on my 1974 ST90. would the OEM CT110 carburetor you sell be a good choice to run with those upgrades? If not, what carburetor would you recommend using on an ST90 with the big bore kit and performance cam? Thanks. -Will
-DRATV: that would be a great choice
i don't know if the jetting is correct, but it should be very close if not
thanks

-Me: Hello. I went ahead and bought the OEM CT110 carburetor. What intake manifold and carburetor insulator do I need to make the OEM CT110 carb fit on my 1974 ST90?
Thanks. -Will
-DRATV: what are you going to do about the air filter ? do you want to keep using the stock one ?
-Me: Yes Id like to keep using the stock air filter if possible? -Will
-DRATV: then you must use the stock manifold and try to rig up something to adapt the larger rear of the new carb to the smaller hose coming from the stock air box
-Me: Any suggestions on how to do that? -Will
-DRATV: not really , sorry
-Me: Would one of your carb to air box boots do the trick? like 17E or 42C? -Will
-DRATV: Sorry i don't have anything on hand that will reduce it
Does anybody know how I can "rig up something" or is there someplace that makes custom airbox to carb boots?
Thanks,
-Will
