I just picked a sweet little XLT from my brother for 400 bucks. I want to raise the bars but I don't want the extra cost of longer cables. Does anyone on here know how tall I can go before I will need longer cables. I figured I could go 4-6" before I have to extend. Also I think a bar riser is what I want. If I replace handlebars I don't want to get new grip heaters. Any information would be great!
