MK65 with high compression head?

Pablo Puchasso /

Is there much advantage to using a high compression header for a Metra 65cc kit? If so, would I use the 70cc one from mopedwarehouse?

Re: MK65 with high compression head?

i run it, and i think there's some advantage to it. the metrakit's a torquey, low-rpm power kind of kit, so raising the compression ratio really plays to its strengths. and yes, you use the 70cc head - or i think you can get 65 cc hc heads from 50cc.nl. but i run the 70cc head.

THANKS for quick response! I guess I'll break it in with my stock head and then when I have some extra $$... get a high compression head. Seems like people in that other thread are still torn between 70cc and 50cc heads though. hmmm
