Well it sounds like you are at least getting the attention you deserve fixing those motors. Nice of a vendor to stand behind their offering. Well, not nice, it's important that they do!
Gosh they sure are nice looking little engines!
I looked at them again earlier today...
If the new version tests out well I might get one to run for a while.
I'll sell this motorized bicycle I have now soon as I know it's running tip-top and reliable.
Well, as reliable as an ht can be... lol
