70bbk, 17.5mm Carb Jetting Help

[mkksat]

So I ditched the Chinese 14mm Amazon carb that came on my scoot and installing a TK 17.5mm. I have 85, 88, and 95 main jets. Bike was starving with old stock carb-size set up. Should I start at 85 or 88? Just not sure now that I have a slightly larger carb would I still need to up-jet a little? I noticed the new TK carb air screw is turned all the way in, I’m guessing it probably needs to be backed out a little?

Here’s my set up:
2002 Bugeye
Malossi Sport 70bbk
Cf reeds
Malossi OR kit
Technigas Silent Pro exhaust
Stock air box w/ snorkel

It's always best to start bigger then work down. But three jets doesn't give you a lot of scope for tuning.
You might well end up in the eighty range, but I would of started higher to be sure. Every bike is slightly different.
