There are a few places to start. We have a how-to master thread, which contains a lot of graphically-illustrated solutions for many problems and modifications. They were all done by members trying to help others out. Find that thread here:
Another place we have a similar (although smaller) collection is at the main website: www.yzf600r.com . Go to the "How-To's" section.
Lastly, the search function may help you find what you're looking for. While new threads are always welcomed, do a little background searching first to see if your question has already been answered. If you still have questions, ask away, but doing a little pre-check work will save you (and everyone else) some time.
