I have a Kawasaki TD24 motor on a weed whacker. I was going to order a TD48 cylinder and piston, and replace the bearings and crank seals to get it up to snuff. I thought why not port the motor as well. I've read up about porting these motors but the port was done for just a traditional 2-stroke motor. However, I have software on my computer and plan to run a tuned pipe that I'm going to build myself. I'm wondering what port durations and shapes I should be using with a tuned pipe. Also, any recommendation for carb mods or an aftermarket carb?

Thanks.
