first, welcome to TT

2nd, what bike do you have?

3rd, it sounds like you need a fuel screw adjustment, do you have an aftermarket one (zip-ty, etc...)

4th if you crack the thrott'e open on a thumper it will bog. You need to role the throttle

You should be able to fix that with leak jets and a correctly tuned AP. Look HERE for "Tuning The AP Squirt". There's a wealth of other info there, too, that applies to your bike as well.

did you just come off of a 2 stroke? you'll get used to the roll on throttle. but first try messing with the fuel screw.

Raise the needle to 5th clip and adjust the fuel screw. A good starting point is half a turn in from what you have now or 2 turns out from seated position.
You can also raise the idle a bit. I had a small bog too and this cured all of it. I was lazy and only changed jets first and did not raise the needle, but it has to be done too.

it is underneath the carb through a hole on the front of the float bowl. you need a short but skinny screwdriver to adjust it. I would get the extended screw. they are like $20 and most shops stock them
