jetting advice needed

My bike after letting off at the end of the road will let out a back fire everytime around 4 grand and also stumble at the begining when u let off slow from wide open. I figured I was a little rich so I toak the plastic washer out of the needle clip so it would lean it out half a postion. Now it doesn't backfire or hesitate and seems to rev out faster and I like the throttle responce. But I notice it lost its low end wheelie power. Before I change it I would crack it in first and it would pull a good wheelie and also had a ton of bottom end torque. Now it picks up the revs so much faster. What can I do to get my low end grunt back without putting it back to where it was? I was thinking of dropping the main jet one size and put the washer back in and see what it does. Please post away. Man I forgoten about this forum!!

Curtis you need to tell us what bike and carb you have.
Ever since my accident I have trouble reading minds. And Phone booths freak me out.

Re: jetting advice needed

I lefted the needle the same and drop the main jet down one size, What a difference. The bike is alot faster than it was before. Bottom end seems good now too, I turned out the fuel screw almost all the way. Does anyone know what back shock would work on this bike?
