I have some very slightly used CR31's that right now have about 4 miles on them and a short time on the Dyno.
We found out after getting the engine complete and doing all of the porting the carbs are not large enough so now I have to buy CR33's.
My CB750 engine has had major build and is closer to a 1000cc than 750 and the engine is starving for gas at WOT. My engine builder is getting over 80 HP to the rear wheel but believes there is more.
So I am willing to sell these for $625.00 and I will ship them free in the continental US and they will be cleaned of fuel before shipping.
I believe we still have the box some where I will look tomorrow.
But if you are interested it will take a few days to get them off of the bike and cleaned up and ready to ship.
They will fit any 1981 CB750 KCF, CB900 C&F and CB1100F.
