I have a good question to ask all engine companys are looking for the best of two worlds with engine power lowend torque and top end speed . how hard would it be to come up with a exhaust valve, like the 2 stroke skidoo snowmobile engines . watercraft and the older dirt bike engines. works by spring pressure with the slide in the exhaust port , small port for lowend, the slide opens with exh pressure and fully opens for top end and make it adj with diff spring rates or a adj cap. just wondering been thinking about trying to make something work .:D
That is a very good question and one i am suprised i had not thought of as i exclusivley work with Rotax engines and know how good these systems are It,s not just the low & high end power benifit but it greatly improves fuel economy also.. Hmmm ;) Dave |

I picked up a couple of plus4-c motors.For my buggy and my 14yr daughter's. The cranks are supposed to be even lighter "drilled way deep" would you recommend filling the cranks.

Monty
Monty, Please can you tell me a good top & bottom end setting for a p5xlt with a 9901ss pipe and 41029 header. I have a 6.5mm venturi installed at the moment as i need the best mileage possible. If you think another venturi would be better please let me know. Im running a losi eight 2.0 buggy.
Thanks;) |
