Lamey doesn't do Yamaha stock porting - he makes custom, high dollar cylinders. Call Paul (JrMagoos) if you're interested in a Lamey.

Porting refers to changing the physical layout and shape of fuel intake ports, transfer ports, exhaust ports, all found in mostly the cylinder, and a little bit in the cases.
This is something you should pay a professional to do for you - expect to pay at least $300 for this, more like $500 (you supply the cylinder!). I believe case porting adds another couple hundred.
Give Paul @ JrMagoos a call (www.jrmagoos.net)

Oh, there are several "packages" of porting, ie race porting, and freestyle porting.
You would want freestyle porting, which greatly increases your engines power all throughout the RPM range, but mostly on bottom and mid ranges.
