Do a plug chop at the speed you have issues with and see whether you are rich or lean, guessing waste time.

Greetings:
My advice:
When in doubt, Richen. Try a 42 first.
If it's worse, then go down.
Make Sure there are no vacuum leaks for sure. Running better on Choke suggests it's Way lean.

So did you find the right mix?
I would like to know what sizes you ended up using if you dont mind.
I plan on doing the same thing with my spree.
Also, whats your top speed and how much do you weight?

What is this insane worry about rider weight and top speed? The weight may effect acceleration but the difference in top speed will not be enough to measure.

Haha ok.
All I wanted to do was ask for the top speed and to get a relative sense of it all but you're right.
Hope you found your right mix.
