trx90 jetting

[911]

i put a slip on pipe on my sons 90 and i am wondering were to start with the jetting. i don't know if i will be running it with or without the lid so any help in a starting point either way will help! thanx:)

I would probably try leaving the main jet alone and richen the needle 1 clip position, that should be good.
