What size jet

[Bumblebee]

What size jet after new intake and uni filter and gutted exhaust? I also am wondering which roller and spring for the carter 150 is a good upgrade. I ride mostly trails and the occasional jump.

i would try between 130 &135 jet --1500 spring and 10 gram rollers or 12gram sliders

Thank You!

after rejetting do I need to adjust the air fuel mixture screw?

[BuggyMaster]

You might but not always. Depends if you actually had to rejet the pilot jet as well (which in most cases you will not).

I would rejet using a 125 jet, yellow 1500 torque spring with 12 gram rollers.
