Well, since I discovered that my 3.1 crank kit did NOT come from the supplier pre-balanced. (yet I assembled the motor anyway... heh) I have to take it back apart again.
I'm going to try to port / polish / port-match my intake setup even BETTER than I did before. I did it earlier, but I'd like to finish the job up.
I remember seeing an old episode of Shade Tree Mechanics, they had some sort of a pipe-cleaner tool that would attach to the end of the power-drill. It had a series of flexible metal sanding flaps on it. You could insert this flexible sanding device completely into any of the ports, and it would clean out, sand out, and polish the insides of the ports. It could go up to a 75 degree angle or something. Does ANYONE know where I can get this? And if this never existed, and I just made it up in my head somehow, can someone tell me how to get a patent?! hah
If not, does anyone know of a good port / polish kit?
