Default what do for my rejetting on my warrior a 150 or 140

without any rejetting it used to be a 145 and it didn't run nice at top speed it like almost bogged but and backfired now i put in a dyno jet kit and put in a 144 jet but goes nice at top speeds but backfires when i deaccelerate (let go off the throttle) a big yellow flame so what should i do a 140 or a 150 please help

try a 147.5 main. and whe n u decel it's bumping unused fuel into the header and when it gets fresh air it reignites.. this can be caused from btoha lean AND rich condition..

if i put a 150 in would run way richer wouldn't it were gonna try with a 140 and if this doesn't work will put the 144 back and drill holes in the airbox it wont decrease hp with a smaller jet or will it decrease hp
because when we had the 145 in it backfired way more and didn't run at maximum speed

tomorrow were trying the 140 because if it is backfires it means it has unused fuel so we have to go with a smaller jet cause with the 144 it runs way nicer at top speed than the 145 and if this doesn't work will try the 144 again with drilling a big hole in the airbox. is the backfiring possible of no back pressure it is all straight.
