Just bought my first VTR, a 1998 red model,42 000 miles, the red ones are always the fastest ..........

First impressions are great and alot of bike for the money, it has a lower fairing belly pan, plus manual camchain adjusters and a few other bits and bobs.
What I need to do first is to raise the handle bars about one inch. Are there any other Honda bars that will achieve this ?
Also:
How are the valve clearances controlled ? Shims ? Screw type adjusters ? Other ?
What should I also look out for ?
Cheers
Matt
