Upjet from Sito+ to SIP Road 2?

I have a 1983 PX150E with a DR177 kit and an SI24.42E carb with a 118 main jet.
I’m shortly going to replace my Sito+ for a SIP Road 2.
Would I need to upjet from Sito+ to SIP Road2?
I will plug chop, but it would help to know what to expect.

Thanks for that Heggie

yeah, that's what I put in my sister's when I fitted it and she's been riding it for 7 months, everyday, with no problems.

Got a P200, going for Sip 2.0 exhaust plus drilling the heart out on base of air filter. 120 main jet sound ok?

i have a 2005 genuine stella (lml star) that had a sito+ and i ran a 100 main jet. i put in  GGR carbon fiber reed and switched to a sip road exhaust and now run a 106 main jet. i hope that gives you an idea of how many to upjet to start with.
