More RPM after Gear Upgrade

[AylmerFreerider]

Hey all looking for some advice on this now.  I have upgraded the gears now.  It had a 14/54 and I was able to pick up a Vitality 50 2T and swap the gears from it.  They are 16/53.

This works out to a 13% increase or remarkably 13kph but my scooter seems to be not able to get past 7000 RPM and still stuck at 68kph.  So I am going to try lighter rollers and see how that works.  Before I was getting 68kph at 7800RPM

Set up is as follows

72cc BBK
92 main jet
1000 RPM Contra Spring
6.5gr rollers (just installed 6.2 to see how it goes, I also marked the variator with a marker to see how high the belt will go.)

Rollers don't affect top speed, only acceleration.  You're on the right track with the gears, but now you need more hp to get a higher top speed.  You're making the scooter work harder. Usual remedy is a BBK.  With 100cc and your gears, and nothing else, you should be able to make 80km/hr. There is no substitute for cubic centimeters!

I have the 72cc BBK installed.  I could upgrade one pipe (from technigass Silent Sport to the Next R) and a bigger jet.  I am getting more power since upgrading my air filter.  Holding 72 now but hoping to hold 75 as a goal.. I wasn't looking for a huge boost just enough to be safe on the 70km/h roads.
