Post by: TauEffect on March 21, 2013, 08:58:36 PM

Saw this big valve head on scrappydog.com...i was thinking of grabbing this but wanted to hear some of your opinions or ideas about other options.

The head can be found here: http://www.scrappydogscooters.com/139QMB_50cc_Performance.html (http://www.scrappydogscooters.com/139QMB_50cc_Performance.html)

Not worth it. get a 125 or a bigger scoot. all I have seen never last long after its on.
the scoot needs a good brake in time after its on your you will blow something.

Blue, you don't seem to have good luck with bore kits. What brands/cc size have you used? I've talked to Jeremy at enviromoto and he recommended the ncy 72 kit (no head). He said its still reliable and you get much more torque for take off and hills and such.

Any modification is chance for problems because kymco didn't design it like that. That's part of the fun though is tuning for some.
