OK...in a nutshell:

Ordered Kazuma 50cc on 8/5
Recvd on 8/10....and assembled. There was an electrical problem (+ batt cable gets hot....blows in-line fuse)
Called them 8/11...they ship a voltage regulator same day, after diagnosing the problem on the phone
They shipped it priority mail and I recv the part on Sat 8/13
Installed.....IT WORKS
8/14 ........gave it to my 4yr old...(b-day)

Thanks for the help Raceway.

I will post an update on performance later...so far.....so good.....
