It's probably running out of fuel. You probably have a plugged line, filter or screen somewhere. When it sets a while the gas slowly seeps into the bowl and when you start it up after sitting it just runs till it runs out of gas RPM's slowly building as it is running out of gas

Just bought Aprilia RS125 had a new barrel and piston fitted a week ago but when first started keeps cutting out. Cant even restart it now. Any suggestions. Have cleaned plugs and carb.


If it cranks over easily, normally, then I would suspect the spark, but if it won't spin over, somebody got something too tight. Did you check the oil? How about the mechanic, did he oil up the new piston? How about the fuel? Fuel pump? Choke stuck on, was the timing set? Does it have an overhead cam? Check the belt? Check the timing again. Then go to the coils. Run/kill button, kick stand switch, is it stuck in gear? Check this stuff out.

Bike won't rev up


Take out the exhaust canister from the cylinder and check the exhaust port.It may be jammed from burned oil.Clean it very carefully by scratching it with a bended flat screw driver but don't scar the piston.While you are in there move the piston up and down to check for scratches.Also make sure the exhaust reed valve is working properly
