NO WAY!!!!!!!!!!!! A 1968 CL THREE FIFTY HONDA WON BAJA 1968 not a 305cc CL. Check your history and your facts.
Sorry man but you should check yours. It was a 305.
You used to be able to buy high compression
pistons and high lift cams for the CL 305. The kit went for about $30. You could find them in the back pages of just about any magazine like popular mechanic.
It made them into screamers. They could pull the front tire off of the ground as
high as you wanted merely by acceleration. They could run off and leave a 450 in the quarter mile. I'm not BS ing you either
