Hey guys,
my UZ50 scooter has problems accelerating within the first 10 minutes of use, it idles fine, but when i rev it, the engine will begin to pick up revs but then skip revs and the engine has even died once trying to put the revs up. After 10 minutes of use the scooter will drive fine which lead me to think it just needs to warm up and that its normal for scooters to do this when its just cold but this problem doesn't seem to happen depending on how warm or cold it is, it only really depends on how long im riding it for.

Any help would be awesome
