I got my son in laws 2009 s150 carburetor type giving it the once over since he has not been riding it much. I was the previous owner so I know the history of the scooter.
It has 17,400 miles and has been maintained by a good local shop whenever something was needed.
The critters got into the thing and ate some wires (again) for the front lights,
battery was dead and would not start.
Charged the battery got it to start with starter fluid but would not idle.
Fixed the wires to the turn signals and front brake switch, took the carb apart and cleaned it but honestly it looked pretty clean blew out the jets with air compressor.put little wires through the jets seem to be pretty clean now.
Got it to idle great and seems to run smoothly.
Went for a test ride a couple times and it acts like a 50cc no pep.
Happened to have a new belt and variator nut in my parts drawer, installed that yesterday and it runs the same no pep. Rollers looked good so I cleaned up everything and reused the stock rollers.
It is still
Slow off the line and can't get it above 40 on the Speedometer.
Been driving it around anyway for errands and this is not the speeds I remember this was capable of.
I'm more of a vintage guy so any suggestions on what to look for I'd be grateful before I pull the carb back off.
I got thinking last night maybe a clogged muffler? It has the original stock pipe and is totally stock
Thanks I'm advance for any advice
