Would this mean that if I cut the intake port to much it would't be devastating for the performance because no blow back is possible?
Also, when I grind the ports do I want the grain to be linear along the ports or round inside the walls? Or do I simply polish the inside? I'am not certain on either as if the surface was polished the gases would attach to much to the material?
Sry for stupid question just trying to learn :whoa:
Randomly cutting any port, intake, exhaust, or transfer, can have horrible results if you don't know what you are doing.
Cleaning up the ports and getting rid of casting irregularties is a different story. You can do that without changing port timing. Intake port should usually have a somewhat rough finish. Exhaust should be polished to keep carbon from sticking.
Stockholm kicks ass :laugh:
I got to visit there a few months back (spent about a month in Jonkoping / Husqvarna).
To the original poster -
I would not use JB weld on ports. It doesn't handle heat well, and there are chances it could flake off. I can't for the life of me remember the name of the epoxy that guys like Eric Gorr use.
