HELP!!!!!!!!!!
After doing a TT search on "yz timing wr250f" -- I've just read that the YZ timing can no longer be done on the 03 WT250F. One sample statement:
**********
One of the TT members reported a few days ago, that it doesn't work to change the 03 WR's timing to YZ position, as per the 01/02. The reason is that the 03's new auto-decompression cam will not develop enough compression to start.
**********
Some say it can be -- with new YZ cams. Others -- if I scanned it correctly -- say the YZ cams cannot be used. One put it this way:
**********
The YZ cam won't work for WR timing and the WR cam won't work for YZ timing. That is because the auto-decompression mechanism is installed at a different degree point on each of the cams. When you move the cam timing, the auto-decompression is activated at the wrong time effectively opening the exhaust valves too early (loss of compression) or too late (loss of easy starting).
You now have to buy the YZ for your WR.
**********
Does anyone know for a for sure whether or not the YZ timing can or cannot be done for the 03 WR250F.
If YZ timing cannot be done for the 03 WR250F -- is an 03 WR450F a better choice for a NEW WRF buyer.
