Jetting questions

[tour96se]

i'm running a slightly ported 70cc kit on my otherwise stock 04 zip r3i. so far i'm running a 95 main jet and it still seems to be lean. i pulled the plug after a trip around a few blocks and it still looks brand new, no oil or gas residue on it.
my question is for anyone running stock pipe,filter, "leader" carb on their scoot, what jet are you guys running? 95 seems pretty high from what i've read from other people with the same setup as me.

95 does sound high to be lean, but it's better to go from feel and plug checks of your own than what other's end up with. Here's some jetting and carb setup info...

If there are any other poor running symptoms, check for air leaks.
