Rotech7, welcome to the forum.

My advice would be before you start bolting on all the fancy stuff (Chambers, Reeds, Jet Kits) you make sure your foundations are solid.
A bottom end check & rebuild can seem daunting first time around, but once you get into it it's not so big a deal. If you have a mechanically adept friend, get them around to help.
If you subscribe to the forum, you get access to the very useful workshop manual.

Before you strip the engine, a crankcase leak down test will confirm all 3 crank seals integrity, you can search the forum as there are loads of posts on this subject.
