Installed a new Gates Powerlink belt yesterday. The standard GY6/139QMB belt of dimensions 669 18 30 seems to work just fine even though it's about a mm wider than the OEM replacement belt for this scoot. (666 16.8 30) My top speed went from 55km/h on the flat to 65km/h. Acceleration is a bit slower, but the belt I replaced was worn down to ~14mm, so I expected that. Hopefully my 7g sliders will arrive soon and help with that. Not looking forward to taking off the big rusty looking variator nut! Put a little penetrating oil on it to hopefully help when the time comes. (Wiped off excess and made sure none got on the drive faces.)
