Technical | How To / More RPM after Gear Upgrade
« on: September 08, 2019, 11:10:26 PM »
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.)
