Re: Need Help
The MTB in the pic looks like a perfect steed for a first build. (Straight forward installation and good vibration absorption).You can get a springer fork or suspension fork for that 1" threaded steering tube.
In stock form, these 2 stroke motors are quieter than a chain saw or leaf blower. The pitch of the exhaust is lower
You can afford a 48cc 2 stroke.
You can add fiberglass (or other) packing to your muffler to reduce high pitched noise
There are posts on this site where members packed rubber between the cooling fins on the cylinder to reduce noise. This actually reduces noise at all rpms.
If all else fails, use less throttle. The China motor purrs nicely a mid-range rpms.
