99 were black
00's were blue
Might want to look into putting a steel rod down the steering post. There is a thread here in the Yamaha section started by "Frostbite" about it.
I know 99's (I am thinking the 00's did also) had the Jack shafts can be a problem with breaking. Find a 01 or newer
Gearing is a tad high, most like replacing the top gear with a 20 tooth sprocket. I did this an helped the low end, lost a bit of top end speed.
Mountain Performance Transfer enhancment kit is a good $50 spent IMO
The pipes will wake it up. Just watch the wiring on the clutch side, right by the top shock mount. the 2 wiring looms going to the speedo/tack/headlights. I put that plastic covering and blacked taped mine. Also rerouted the under the metal front support. I did start to melt mine when I first put on the pipes, without doing this
The pipe in the number 3 cyclinder, stick the flange into the pipe then put the pipe into the belly pan then bolt up the flange, the other 2 you can put the flanges on the motor then set in the pipes.
Get some of that copper Silicone, and use it on every joint on the pipes. Also put a bead of silicone under the stinger flange plate were it sits on the bellypan where it exits the bellypan.
THE MOST IMPORTANT, the flanges for the pipes that blot to the motor, those go on 2 differet ways. One way is correct, and the other will block off a section of the exhaust port on the motor.
Put the flanges on and before putting the pipes on run your finger into the flange where the flange and the exhaust port meet. Try it both ways and you will see what I mean.
