The Stage6 Sport Pro 70cc aluminium cylinder has always been an affordable yet very high (European made) quality cylinder kit which has long been popular with in scooter tuning.
Now Stage6, with their new Sport Pro MKII, are taking it one step further!
This MKII version of the Sport Pro is a completely new design and includes new transfer ports design which gives a 2 hp increase over the earlier kits.
With the right components this kit can make 15-17 hp straight out of the box.
Cosmetically this kit resembles the pentagonal shape of the R/T cylinders and the head is a one-piece construction with cast scavenging passages for better heat transfer.
The piston used is a replica of the R/T version, with domed crown and 0.8mm ring to increase performance and improve thermal stability.
Use with short reach BR9HS spark plug.
This kit will also fit the Chinese 50cc 2-stroke 1E40QMB engines but only if you fit an Aerox/ Jog exhaust.
*Choose between 10mm (standard) or 12mm (oversize) gudgeon pin.

I would use the Stage6 sport pro variator kit. It's specifically designed to be used with it and will normally work with the rollers it is supplied with when fitted with a decent revvy sports pipe Stage6 Pro Rep. The Stage6 oversize would work just fine but is a little overkill for this kit considering it is much more expensive.
