    I am not sure 100% but I believe it does.I don't recommend it though cause the two exhausts are different inside and probably will not work properly on your bike.

Can you register a yzf 450 for street use


It would be possible but probably too expensive, there are some private compliance certifying companies that do the compliance plates for many of the low volume imports. but you would need most of the WR electrics and muffler. Easier to start with a WR and fit the YZ cams.
So even if you can find a WR wreck that has the compliance plate and rebuild it with the YZ bits,it would still need the WR;s engine number

Checking my valve clearances I found my rhs inlet was 0.22mm which is 0.07 above tolerance as stated in manual. Will it tighten as the valve seat wears or should I get shimmed? All others were in tolerence...


It will not get tighter ,try shimming . Valve clearance is allowing for heat exspansion .a extra large clearance is noisy and will not allow the valve to operate properly .too tight a clearance will not shut off the valves and cause exspansion loss in the commpresson stroke .And in some cases the piston may hit the valve.Resulting in a loss of power.A loose or large valve clearance is noisy and will give your enging a sluggish performance.
