I bought a '97 Suzuki Katana from a guy, who, I really shouldnt have bought a '97 Suzuki Katana from. But anyways...

I have been plauged with a number of problems, but a very interesting one is the fact that it is redlining nowhere CLOSE to where it should be. Instead of 13K (I believe, it has a digital tach) it will redline around 6K, and around 5400 it feels like it is going to vibrate it's self out of the frame...

This is kind of a problem considering it is designed for higher revs, and at 6/7 grand it will smoke if I rev it up there.

I am new to motorcycle repair, but I am really trying to learn and understand my bike better. So if you have any ideas, let me know.

First thing to check is your ignition system. Check all the wires and connections, especially the grounds. The coils may be failing as well, but it's hard to check them for faults at a certain RPM. A bench test is about as good as you'll get, probably.

Or it could be carburation.Your main jet tubes and needles could be worn, making it run rich at those RPMs, and Suzuki's are known to have rapid wear on those parts.
