The exhausts are the same across all years and models eg an exhaust from a 2004 TTR250 will fit yours with no modifications - and vice versa. 

Jetting will depend on which exhaust you buy and whether you make modifications to the airbox and filter.

So here we go. Here are some current modifications that I want to make that I had originally had no intention of making, but seemed essential. 

#1

Problem: Front Master Cylinder window is sealed and you can't see the amount of brake fluid inside. Also, the bolts that hold the cap on are rusted and stripped. Thirdly, the plunger that is pushed when the hand brake is applied no longer has a spring, therefore it does not get fully pressed when the brakes are applied.

Solution: Buy a new front master cylinder from partzilla (1), including the bolt (7). I will be buying the an ASV rotator clamp from motosport. Also, thanks to Brian, I have already ordered the stainless steel allen bolts for the cap that seem to want to corrode very quickly.

Parts:

Problem: My front headlight is not very bright and makes night riding pretty dangerous. 

Solution: There are a couple of possible solutions here. I have found a few options of headlights and bulbs that I would like to buy and hope that people will add their input. 1) Just add a better headlight bulb found on partzilla (link is below). 2) A new LED headlight by acerbis found on motosport. 3) A cycops headlight by acerbis found on motosport.

Parts:

Acerbis Vision LED Headlight: http://www.motosport.com/dirtbike/Acerbis-Vision-HP-LED-Headlight

Acerbis Cyclops Headlight: http://www.motosport.com/dirtbike/Acerbis-Cyclops-Headlight 

Any advice would be great. If anyone sees any compatibility issues or problems, also, please help me to understand. I'm definitely not a mechanic and buying online makes it that much more difficult. I plan on buying these in the next few days so please give any advice or ideas you may have.

The Raid headlight takes an H4 bulb and also the European pre-2004 blue TTRs with the big headlight uses them. The pic below shows the H4 fitting on a headlight glass. I think these headlights are the same as on the Australian blue TTRs.

Another question: The bulbs on the 1994 headlight look like they are the same on the 2000 model headlight. I have looked at the possibility of a HID xenon option and they sell one for the 2000 Yamaha TTR250. Is the bulb and the wiring the same for both headlights?
