I have the VM26 Mikuni carburetor on the hawk now 110 main jet middle needle position
1 1/2 on the mixture screw what a difference no more riding around half choked .
It starts and idles on full choke for 30 seconds then to half choke for about a minute
then your off and riding .
I still have the exhaust pop when decelerating but I think that's because the cat is still in the header pipe and is probably igniting the un-burned fuel.
Also changed out the rear knobby for a Shinko 700 4.60-18 it doesn't feel like i'm riding down railroad tracks anymore
much smoother on the street .
