After running my bike for a while with a stock motor, I made a new intake manifold for a CNS carb I got from a buddy. The intake manifold is 6061 and tig welded on the inside. I also made a custom filter for the carb, shes a bit large but it works. It was a bit of a hassle to tune, but the motor loves it, she breaths alot better now.






Believe it or not i turned this manifold with a drill press and a Adjustable hole saw. http://cache.jalopnik.com/assets/resources/2007/05/029-Front_Panel_Hole_Saw.JPG

I am really liking this thread, md!
I have been contemplating using a carb off of a Honda CT70, but it might be too big.

How much more TQ and HP do you think you are getting?

My butt dyno sais its good for another 6 horse, but my butt dyno is usually off. I think I gained about a half horse, maybe a full horse with the header. Its super easy to over rev the motor now, and pulls real hard mid range. Wish I could get a bullit rods and better flywheel, I want a10xxx rpm motor lol. Give a honda carb a try. It should work, a70 isn't much larger than a50
