HELP ME WITH JETTING!!!!!

[BlastyJack]

I have a completely stock blaster and I want to take the airbox cover off! I have a 230, 240, and 250 main that I can put in. I want to know what needle setting and which jet to use. Thanks!!!!

Leave the needle in the middle position. It doesn't need to be moved.Is the oil injection still hooked up?
If premixing add one size
Start big and plug chop to see what you will need. Temperature is going to play a big role in your jetting. The cooler the temp the bigger the jetting will be needed as the air is more dense. Altitude is also a factor.

Ohhhh sorry for leaving out those big details.
Premixing 32:1
Warm ~ 85° - 95° on a normal day
About 1000ft where I live, but about 2500 where I ride
