Sat on a 10 inch agility in the shop. But a averaged guy can only drive straight roads since it's unable to steer on that tiny little thing.

yes on 50cc.had it in about two month but as soon as i put it in had engine problems. had to strip whole engine down as crank case was cracked, only ran it this week realy. the ram plate was tight on crank shaft so i put origanal one on. and used new varaitor and rolers and boss. but will take cvt apart again monday and inspect and clean. will try the new plate on again so will report later. but all seems good. so far i would recomend it.
my new varaitor... Kymco Agility 50cc High Speed Variator NK900.20
The Naraku High Speed Variator is considered one of the best variators on the market for the 139QMA/QMB engines. The variator comes supplied with matching rollers weights that are suitable for use on all setups, however 63cc on up receive the best performance improvement. The variator is 10% lighter than standard variator and comes supplied with larger more robust sliders. Also in the kit is a shorter drive boss (the perfect length for these scooters) and set of high performance rollers(5.3g).
The 5.3g rollers are suitable for 50 - 72cc kits . As always variator tuning is in coordination with engine tuning and these roller weights may not give the best improvement if you have carried out further tuning work.

Fitment: 139QMA/QMB

cant comment at mo as only had it in for a week.
Try the Cdi, smooth boss, 82 main jet, and 5.5g-6.0g rollers 1st.
Then 1000 or 1500 rpm rated TORQUE spring, clutch springs make little difference imo, also race variator maybe.
Kymco (in their infinite wisdom ) made a hole for that - it's in the tupperware, just above the left passenger footrest.
You need quite a long and thin screwdriver, but it works really well...
