you have to be very careful going smaller on jets then stock. is everything on the bike stock .if you can just give me a call 1 day 21576 86418.this way I can actually talk to about the carb.

 

your float might also be stuck shut so therefore it's not getting enough to you until you hit your throttle. do you know if the bowl is filling up with fuel ,you may not be running rich and your air screw should be adjusted to about 1 and a half turns out .
