Mx banshee build

[Richard2112]

Building banshee for mx. Am I the middle of a rebuild. Nothing really started yet everything is apart at the moment. Have a 4mil lr wisco crank, 795 wisco pistons, 4mil ported and bored cylinders. Might get more port work done not sure yet. Trinity 1 Into 2 intake, plan on running either a 33 or a 35mm keihin carb. Cool head with 18cc 9 degree dome for race fuel. Either going with dmc ailens or 916s. Looking for imput/ suggestions. Am just looking into the motor right now nothing else dont want to hear about suspension yet.

Seems that you have more than enough power.

For MX? We should talk about suspension first. ;-)

Imo and many on here ditch the two into one intake and look at PT pipes if you going to be doing mx. Suspension is a must if you want to go faster with confidence.

First, you should worry about chassis setup. Suspension is way more important than max power for MX.

You don't need max power. You need reliable power. You really don't need a 4mil for MX. You need to make sure the porting on the cylinder isn't for top end power. Don't use trinity manifold as it sucks. Yamaha makes the best single carb manifold. Talk to david.

Plus you can get adaptor plate for the carb intake from a site sponsor

My bad it is a chariot 1 into 2 intake

Still, shit manifold.

[Richard2112]

What would be the better carb size for a single carb setup and is it worth running race fuel 

 

[ZillaFreak]

I would say 35mm.

So I took a second look at the cylinders that I have and it looks like that they were not ported. They were just cut for the 4 mil

Should I go with a keihin 35?

A 35 with a billet bowl.

Can I do anything to the manifold to make it better? I dont really wanna buy a new one. 

[Richard2112]

Am thinking of moving away from dmc and looking a pro circut pipes. Heard that they have better low to mid power.

Send me the cylinders if you want. I have a little downtime for the next month or so.
