Ok, this is a wierd one. I have a set of Renthal bars on a 99 YZ400, not sure which model since they were on the bike (used) when I got it. They are fairly thick where they are in the clamps, if that is any indicator. Here's the prob: Whenever I ride my bike for a long period of time, say, about an hour or so, my knuckles on both hands start to get sore right where the finger meets the hand. I thought my gloves were too tight and putting pressure on the top of my knuckles since I have really long fingers (i'm 6'5" tall and 181lbs.), but that's not the case. The gloves fit fine. I am starting to think that my hands actually wrap around the bars too far and puts too much tension on my knuckles. What do you guys think? Thanks for any input!
