I want to ask a question but don't want to put you on the defensive. Please don't take this the wrong way but I'm having trouble imagining someone struggling with the reach with the stock bars on an '02.
Are the bars not stock? I wouldn't have called the bars on the '02 swept back.
What isn't comfortable about them? I am wondering if maybe we can help you without bar risers.
The reason I am so surprised is because I am riding an '04 with the same stock handlebars that are on the '02 and I'm very small (4' 10" tall with a short reach) and the bar setup is very comfortable for me. Hmm, having another thought as I am typing, are you too tall for them?
Anyway just hoping we can help you save some $$!
