ANY 2-STROKE 50CC Jonway Performance Parts out the

[johnnydoube]

Does any know of an 80cc or whatever size, performance kit that would fit a Jonway 2008 YY50QT-6A Scooter.

It would have the clutch springs, exhaust pipe and carb jets as well as the cylinder, piston, wrist pin and circlips and gaskets.

This is a two-stroke model, I have seen plenty for the four stroke.

Some said a Minarelli Cylinder would fit, maybe like this one www.treatland.tv/minarelli-polini....cc-cylinder.htm.

I am not sure.

The engine family is 2008 shanghai shenke 8JNYC.050SA1

Is there a cross reference number to Minarelli it could help.

Thanks -jOHNNY

There seems to be NO two-stroke replacement parts.

Most minarelli/jog engines will be marked with 1E40QMB or 1PE40QMB on the top of the transmission section of the left side case near the rear. I think Jonway does use the minarelli. Before you go ordering anything, find out what size your wrist pin is. It can be either 10 or 12mm. Variator spline sizes vary as well. They are 13 or 16mm. If you aren't going to tear the engine down and just wait for the big bore kit, you may wanna try checking the diameter of the splined section of the crankshaft that the variator rides on. 13mm should mean you have a 10mm wist pin and 16mm should mean you have a 12mm wrist pin.

There are tons of parts out there if it is the minarelli, stock and replacement. HERE is a big list of scooter parts retailers.

Your link doesn't work, but I see it says Polini. Polini makes very nice products. There are tons of choices out there. You can get good low end, higher top end power, super high revving race kits... whatever. All sorts of choices for clutches, clutch bells, variators...
