Hi all, I just made the switch to blue after many years on red and orange bikes. The last Yamaha I had was a TT500 from way back in the day. My how things have changed. I have been reading all the posts about the free mods and how corked up the bike was and was getting a little worried. Either I'm missing something or everyone is making this stuff sound too hard. My XR650R required just as much or more to get it running right too. I have yanked the airbox baffle, set the fuel screw, pulled the exhaust baffle and this thing is running pretty crisp and strong. I am around 2500' and the jetting feels real close stock. I think I could go up one on the pilot but otherwise it runs strong and smooth. I will be getting a '04 needle so I have some adjustment there and the Lowedog kit is on the way. The manual says the main jet is a 165, Indy, others, do you think thats close to right for my elevation? I remember reading an earlier post where Indy told someone to drop back to a 165. I'm also confused about why people are drilling out the rivets on the exhaust. I just pulled the baffle and put the spark arrestor back. That made a major change without removing the rivets. Am I missing something? Thanks for sharing the knowledge.
