Anyone know if some work has been done on a 3 or 4valve layout? Just conversation.



I have had a 4 valve design in my mind for about the last 3 1/2 years now. And the groundwork for this to become a reality was laid down last month ! However it is for a very specific market. And I have serious concerns whether it will be outlawed within its classes that it's intended for.
A 4 valve retro fit is not something that I'm intrested in pursuing. To do something really good is complicated And extremely expensive for Valve train parts. And on a retrofit it gets even more complicated and the design gets compromised.
