Re: muffler drilling HELP!!
1) look around this forum for details. use the search feature.
2) dont drill holes in your muffler. you want to drill out the baffles inside the muffler.

Re: muffler drilling HELP!!
Drilling out holes in the muffler will have the same effect as if you were to clean out the carbon of the muffler. I would start with cleaning it first...
Re: muffler drilling HELP!!
your hopes of tuning a moped without taking parts off are slightly unrealistic.
roll up your sleeves, scour the forum, and prepare to get dirty. clean out your pipe, do the intake mod, etc. if you don't mind sub-par acceleration, the pully mod and/or belt mods may be for you. keep at it, you'll be going 30mph all day no problem. but you will have to get a little dirty.
best of luck, any questions, just ask
