Default Re: Do slant heads really make a difference in power?

[QUOTE=xlite;133961]That paper label is on all the motors I got from Zoom... even the 50cc. Why they would put a 80cc label on 50cc bike is beyond me.

OK, this is interesting and important. I actually ordered a 50cc from Zoom. I assumed I had gotten a lucky break when I read the sticker. As far as I knew this was an 80.

So to clear up this piston issue is there a measurement I can take to confirm my engine size. The piston diameter should be the give-a-way right? I hope I have not made things confusing with unintentional dis-information. Sorry.
