Another one that's giving me headaches
The scooter was presented with revving issues, it ticks over but when revs applied it increases then settles back down to tick over, increase throttle revs go just above tick over then settles, this goes on until full throttle, but engine will rev up for a few seconds then settle then rev up then settle, if I throttle back it will cut out. The bike did run fine before this issue
First thing I checked was the carb, stripped and cleaned with ultrasonic cleaner and carb cleaner checked jets cleaned them and up jetted the idle jet but not the main. I rebuilt the carb and put back together (tried without oil first problem remains) then putting a bit of oil (GT85) on the slide mech with the needle to help it move and still the same.
Compression is good as if it was not I believe it would not start, the plug was dirty and had carbon build up from it, it has a good spark, but it could be as simple as the plug.
It has been suggested that the stator could be the issues but as this is a young lads scooter he doesn't have much money to spend
It does have an aftermarket exhaust and during the carb clean I removed the brass airflow restriction to improve the air flow.
What do you think could be the problem as the carb is clean and the scooter starts but won't rev?
I have added some redx to the fuel
Any help is appreciated as this lad needs the scooter asap
Cheers
