my aerox was always good on hills compared to my mates moped's

one thing thats just sprung to mind though is the tick over speed, its fine when i've just started up and is for about 10 minutes or so, but as soon as i've had a bit of a run out and gave it the beans, it ticks over at like 2500rpm instead of the usual 1500/1700rpm i dont want to adjust the tick over on the carb because then when i've just started it, it wont tick over fast enough, any suggestions?

i dont get the stutter with full throttle but i agree with the 5th gear remark, the revs don't seem to build up unless you go down a hill etc, but i think 67/68 is fast enough especially for the roads i use anyway.
