ok, when i first take out my 50cc Qingqi scooter in the morning, like just after its warmed up enough to take the choke off, i have a s*#$ load of torque & pickup, however, as the bike warms up, it gets steadily worse and worse, until im basically using my feet to get off the line. it dosent affect top speed however. the bike had several minor seizes in the past and is well past due for a ring job, but i just found it odd how performance DECREASES as it warms up. what could be causing this?
by the way, the lean running that was causing the seizes has been fixed, now its just this odd speed problem and the smoke and bad gas mileage from dead rings.
