I just installed a 80cc BBK for my moped. And found out I've blown my engine. Right behind where you add the oil.

By blown what do you mean. Is it leaking oil? Does it run? Does it make banging noises?

pumacyclessteve: the gy6 150 engine needs to have the oil changed more than most other scooters .the simple fact that the metalergy and the alloys are not the highest grade like the high end scooters .the errosoin and general wear down of the internal components.is slowe Mar 1, 2013 18:51:10 GMT -5

pumacyclessteve: but i have a 150 that i ride hard i mean hard thats 5 years old and still runs like a bad as whith a power pros custom one off exhaust and a big valve head .i will wheelie at most every intersection just out pure confidence in my one trick pony.stay Mar 1, 2013 19:04:53 GMT -5

Rebel: Yes. Mar 2, 2013 18:49:26 GMT -5

mukradio: Help! I am working on a 50 cc that I can't get it to idle properly. It's starts off way too high and when it warms up, it dies. It's driving me nuts and it's a short trip! Any ideas? I have disassembled the carb and cleaned it, drained and replaced gas. Mar 7, 2013 15:41:53 GMT -5

westonpersons: Adjust your valves to .006". There should be easy directions on youtube, otherwise just remove the valve cover and turn the flywheel so the engine is at top dead center, then adjust the 'taps' on the cam holder for the .006" gap. Mar 8, 2013 15:02:33 GMT -5
