Hi I'm having running problems with this scooter it start every time rides at low revs but I took out today and you full throttle it seems fine but when I let off then rev again it bogs and dies out it has the race pipe and standard airfilter. Any help would be appreciated. Cheers
Has it been running fine before? If so then what changes have you made since then? If none then start by cleaning fuel system out including carb and filters. If its never run well then find out what the stock carb and settings are supposed to be and put scooter back to how the manufacturer's did it. Get it running well and then make mod changes.
