so my understanding is that 9:1 gears are a little too short for a 48mm bore, so what gears do you guys use in your 72cc dios? im pretty light weight and acceleration doesnt seem to be a huge issue.

Get Burnt_Toast's Ruima 8.4s. Good quality at an attractive price. Depending on planned future mods, you could opt for 7.5:1s, but at considerable detriment to take-off performance. Taller gears will smoke a clutch faster too.

Most of my money is spent on scooterparts. The rest is just wasted.

Thanks, some day I will learn to look before I ask. Although much to my wifes dismay after all these years, I still ask... where do we keep the new rolls of TP anyway...
So I am expecting me bbk kit today, so I got the daytona jet kit from daywot and its range is like 90 through 110, so I figure ill try the 105 first and that should be super rich with my current setup. Ill throw 4 oz of oil into my tank when full and with my stock oil pump as well I should be pretty safe right? What should I start my air fuel screw at?

it going to be to much oil going in the engine.The stock injector mixes at around 40to1 and with 4oz of oil in 1.2 gals of gas is around 35to1 so your total is around 18to1 or 19to1 which is way to much oil. the most I would go is 28to1 mixture and use non synthetic oil to breakin.The synthic oil is to slippery for the rings to seat.
Nothing like getting stroked!

If its the belray si-7 oil,thats synthetic so empty it out and get cheap petroleum oil to breakin like penzoil or chevron 2 stroke oil.mix at 32to1 or 35to1.do around 4 heat cycles, (let the bike idle till it gets hot and let cool to the touch)No reving.ride for 5 mins. no more than 35mph modulating the throttle so your not at constant throttle.let cool to the touch and up the ride every time 5 mins till you use up 2 tank fulls.be patient, as you will be tempted to full throttle it to feel the power but don't. check the plug to just to make sure your not running it lean.
