I Need to order some main jets for a new build TS1 and I've seen specs with mains ranging between 115 and 155. I don't want to order that many so just want some ideas as to what range I should buy.

Carb is new and has a 70 choke, 40 slide, and I'm going to try both a 50 and 55 pilot, needles X2, X7, X13. Atomisers AV266 and AV264.

The engine has a 110 conrod and 2mm packer to reduce the timings to a more touring tune. Exhaust is an old '90s Taffspeed/JL road pipe, gearing Li150 - 46/17 - 4.6. Scoot will be run with a RamAir filter straight through the panel.

Any ideas for a decent main jet range gratefully received
