Skyteam Skymax 50

Post by Players Devil » Fri Jul 10, 2020 12:33 pm

Hi together,

i registered here to find some information about the restriction of my Skymax 50cc Dax clone.
Since i could find a fitting dax /dax clone forum i thougt i give the c90club a try :D

My skyteam with a loncin motor was restricted with a reduction in the inlet manifold (singlefold?) and reduction in the air filter. I removed both and but it hardly could reach 65km/h. Then i changed the front sprocket from 13 to 14 teeth but it only got worse.
I then tried removing the cat but it also did make it much better. Then i even grinded the cylinder head inlet and outlet. That gave the engine just a litte "plus" when driving uphill but not much.

Currently I have installed 72cc kit with a special piston for a 50cc head. The engine now has a lot power but still does not get over 65 km/h.
I also tried a 16teeth sprocket. But that is to big. Maybe 15 would be better but the engine is still super weak.
Shouldn't it be able to reach 70 km/h with the 50cc stock engine?

Do you have any ideas?

Not sure...but it could be restricted by the CDI unit, I know some manufacturers do restrict bikes in this way, which limits how high the RPM's will go, say it's restricted to 7500 rpm, does mater what you do, it won't rev out worth looking into

Are you legally restricted to a 50cc due to age or licence?

I believe that standard 50s in the UK shouldn't exceed 35mph, about 55kph due to licencing restrictions.

Read the pinned post at the top of this section .A 50 cc can be a light motorcycle or a moped.
