I bought a Parma High-Comp head for my Motobecane AV7. I'm running a Parma 70cc kit, Doppler crank with 21mm PHBG with 21mm intake. I also have a Doppler ER2 variator installed. I would like it to make it easier to start. Has anyone drilled a spot for a decompression valve on the Parma high compression head? Is there a 70cc high compression head with decompression valve already installed available?
