I have a model CH80, Honda Scooter 80cc I can’t seem to find any online or in person… can you come up with an online or regular store where you could get a performance or non-restricted tail pipe for this type or model CH80 honda motorscooter?
No socalhillbill answers necessary.. Lookin for aftermarket parts for my ch80 honda, if you know where I can get any parts, ( I know that the stock pipe is not restricted) just wanting some options…
If you are a MC mechanic or understand my request anyway, please let me know, I appreciate it
