Some simple Q's about WR vs. YZ
Posted March 31, 2003 - 10:52 AM
1. "The grey wire" retards the timing - cutting it will make me happy. True or false?
2. Can I run YZ-cam timing and still use the WR pipe?
3. Big difference between the WR and YZ pipe?
4. How do I know if it's jetted correctly? On a 2 stroke you check the plug but four-stroke???
5. This is a tricky question and I don't think it's even a good question: How much taller are the gears? I'm curious because I can't decide wether to buy a YZ or WR... I'm worried that it will be a pig if I run dirt tracks......

2. YZ timing will make the bike generate power earlier in the rev range. You will loose a little top end, but I have done this, and I will not go back to the WR timing.
3. WR pipe is steel and heavier, but it also is spark arrestor compliant, which is required for all forest service lands.
4. To ensure that it is jetting correctly, you got a lot of work to do. Spark plug testing is one way, trial and error by riding is another. Guru's here will answer questions as long as you are willing to ask them.
5. Not positive, but I think that gears are only different in 1st, 3rd and 5th gear. (Are you talking NEW, because the new YZ's have a 4 speed gear box, the WR retains the 5 speed gearbox, but both are very capable) Many people have converted the WR for dirt-track racing only, and they do fine.
