Knowledge Is Power

[SuperDave]

The GREATEST upgrade you can get for your bike is knowledge. Here's a link to where you can educate yourself about 2 Strokes, and the downloads are free. Gordon Jenning's Two Stroke Tuner's Handbook, and Graham Bell's Performance Tuning.

Read it. Learn it. Do it. Be awesome.

Those are two of the BEST 2 stroke tuning books ever written, I highly recommend downloading and reading these to anyone who doesn't already have a copy.
I got a few others that are really good, but these 2 are mandatory for anyone who likes to tinker with 2 strokes.
