They make a small impact driver I have used for years for bowl screws. Also, cover every open hole before removing screws. I keep a small speaker magnet near by to stick to the frame and hold the screws once removed. I put a drop of Marvel Mystery Oil on my finger tip and wipe around the intake side of the carb to ease installation. Helpful if your are jetting and re-jetting. Thanks for the vid.

I just need a scooter!

[@seanmayo206]

Mine say it's standard of Japan. Good or no?

What size jets would you recommend for a stock 50cc moped? I’ll be getting a better exhaust for better air flow. Also will be drilling just a few holes in the air intake pod for better air flow. But there’s no videos stating what size is good for a stock moped. My restricter is off in the cvt and I’ll be getting a racing cdi and better spark plug wire. If anyone could help me out that be great thanks!

I think they come with 72 I'd go # 75 for stock probably 88 with an exhaust upgrade
