rebuilt the cv 40 on my 99 FLSTC. bike has big sucker, V&H big shots longs, and EV 27.

put in a cv performance kit with a 48 pilot and 175 main. AF screw 2 1/2 turns out. bike runs pretty good until...

I get going pretty good up until about 50-60. get on the throttle hard and can smell gas. this will also happen at any speed when I twist the throttle open hard.

any ideas?

Does it still run fine when you do that. Do you have split tanks? Upper equalizer tube have a leak? I'd say get your nose away from the tank. How can you smell gas @ 50-60 mph?

the on coming air blows it up to me. don't smell gas UNTIL I twist the throttle open HARD, then I will smell it. don't smell it cruising along, but when I gotta give some throttle to go up a hill or something...gas smell and feels sluggish

Didn't do it before rebuild? Main jet too big.
