So I just bought a second 2011 Tomos from a motorcycle type off craigslist. He modded it with I think its called a stinger exhaust and larger jets.It got a little sketch when I bought it without riding it because the masterlink on the chain was broken. Later, after totally freaking out that maybe the tranny was burned up with the mods, I but my other tomos chain on this new purchase. No tranny problems. but man this mod is problematic. Yes it goes crazy fast for a moped. at least 35 as measured on the drive slow radar nearby but it sure idles super miserble and seeing to me to be in a perpetual too rich state.I have the original stuff also,pipe and jets which he gave me, and might switch back.
so the chain he gave me is a 420 which as people might know is a shade wider(1/16") than the 415 chain that Tomos comes with. Is this a bad idea to use?
I would welcome any insight on the above mods from people who do this kind of stuff regularly. I really don't want to upset my neighbors with a outrageously loud device. They are entitled to peace and quiet.
