Engine build

[tyler73]

At what point do I have to go to bigger carbs from stock my motor is stock now next winter I want to build it up I know for sure I want to put a 4 mil crank in it but how big of cylinders can I go before I have to put bigger carbs on it

[tyler73]

I only want to run on pump gas no race gas

It sounds like you're building a trail/play motor from the sounds of the pump gas. If that's the case, stock carbs will be just fine for any 4mm motor you build.

Yeah it's a dune bike for oregon dunes I don't race

Do you drink from the same bathtub as skeeter?

[tyler73]

After I understood it I liked it

[tyler73]

I think I found a setup I might like 4mil crank stock cylinders with dune port it should work for my type of riding

You could be extremely happy with a solid "dune" type stock cyl set up. Even on pump gas it's posible to have torque and 80HP. Of course they won't lug like big huge aftermarket cylinders would, but guys are doing pretty bitchin' stuff with the stock cylinders. Take a peek at the dyno section. Lotta folks with stout 4mm motors.

Yeah that would be cool to get good power with stock cylinders with a dune port it would keep it cheap redline racing does play port for $100 a cylinder I wonder if that is the same of what others call dune port

Tyler, i have a Redline playport 4mil.  Bike pulls nice.  If you have the extra cash go with his dune port.
