CRF 2 WR some advice
Posted February 04, 2007 - 08:51 AM
I am a CRF 450 riding who is sick of the Valve issused with this damn bike, my buddy has a 98 YZ 400, the original thumper and loves it.. so I am tossed up between getting a XR 650, and a WR450...
few Q's... I know the yamis have the 5 valves, whats the benifits??
valve life, and we talking a entire new valve system and re cut valve seats every 50 or 100 hours like the CRF? or do the WRs hold up? or is it luck? some guys have the problems, and some dont?
what are some Years to avoid? what is the 1st year of the WR 450? i am currently looking at a 2003..
thanks for any advice!!

Run a search for "starter key" and you'll get lots of good reading. Do the same for "valve adjustment" and your evening is spoken for. That said, alot of guys get over 10,000 miles with only bi-yearly valve checks/adjustments. Hope that helps.

I have accumulated over 10,000 miles of trails and street motard riding.
Only one valve adjustment has been needed. The valve adjustment cost $200 from the dealer.
No starter issues ever. I have only had to replace front wheel bearings, jetting, and the drive shaft weep seal.
My friends 2005 CRF450x is slightly faster in a straight line, but he too has been dealing with valve issues.

So, my point being, don't use the Genesis design as a basis for decision. There are other reasons to go with the blue bike. For me- I just switched from KTM, it came down to better pricing, equal performance (heck, all the bikes are so close with regards to performance), better components for the dollar, ergonomics, etc. Service intervals, according to the manual(s) are also pretty close. But, many on this forum report excellent longevity, when doing the required maintenance.
I think that the Honda engine is easier to work on, given the frame design, but that is just an opinion. The Yamaha frame is not a true twin-spar, but more of a mix of the old and new designs.
Imagine being a Yamaha Road Race Mechanic; 5 valves X 4 cylinders! YEEEEHAAAWW!!
