Motorcycle Repair: oil change, panka, pit bike

Question
Hello Mark,
I bought a New Age 80cc pit bike for my kids at an auction and they love it. There is no papers on it so I wanted your suggestion on what type oil I should use for its first oil change (weight & type).

Thanks,
Ron

Answer
For the 1st 20-30 hours i would run regular detergent 20w50 oil. (not synthetic) Once the engine has been broken in, thwn you could run semi or full synthetic oil, but not until the engine has some time on it..
I personally run 20w50 in all my bikes, never a problem

Hope this helps!
