A very happy day, finally bringing home a YZ450!!
The dealer is the South Seattle Sports Plaza in Federal Way, WA. They are the largest single line Yamaha dealer in North America.
My love affair with this bike started several years ago when I rode a buddy's '03 YZ450. I was awestruck with how powerful and light it was. A monster yet somewhat civilized. A true wheelie machine in every sense of the word!
So to finally shut me up about this bike with my 40th birthday looming, my wonderfull Wife pulled the trigger on a left over 'new in the crate' '06 YZ450F - WoooHooo! And yes, she wins 'Wife Of the Year' for sure :)
The only aftermarket accessory we were able to get the dealer to throw into the deal, a ProMoto Billet Spark Arresstor end cap. Here it is installed. Overall a very nice product that was easy to install and fits perfectly.
The original Ti end cap removed, that's right... Ti. Lot's of Ti on this bike including the end cap, shock spring, valves, head pipe, etc. Yamaha pulled out all the stops with their first aluminum framed bike... only 219 lbs dry!
ProTapers came stock for '06, one less thing to I have to buy :)
Stipping some of her parts off to get the carb. out for a rejet. It comes apart very easy and I'm very impressed with the high quality fit/finish of this bike.
She's as beautiful taken apart as she is all put together :)
With the carb out and on the bench the plan is to go up one on the pilot and up one on the main. Also install a ZipTy extended Fuel Mixture screw.
View from the top, under that 'CR' resides the stock needle in the #4 clip position (stock).
Here's the new parts including the ZipTy Fuel Mixture screw, #168 Main jet, and #45 Pilot jet
All the new bit's installed and ready to go back in the bike.
Horrible picture but one of the many reasons why the Yamaha's are better than the rest. 5 valves are lighter than 4 thus allowing more RPM's, less valve adjustments, and less valve issues overall.
Carb back in the bike with the throttle cables re-connected. I removed the slack in the throttle while I was at it.
This was the stock preload set at the factory. They say with the stock spring/preload on the 450's is set for a 180lb - 200lb rider. Since I weigh more I needed more preload...
So I dialed in another half inch of preload... feels much better. I will set the race sag after I have the suspension 'broken in'.
Yep, pure magic :)
She comes back together very quickly with the pieces literally falling into place. The fit and finish of this bike reminds me of my R1 (gone but never forgoten).
The view the competition will see of this bike :) If only the McCallum Bro's could have had a couple of these when we were racing SuperMoto...
According to ThumperTalk, the hot setup on these bikes is to raise the forks in the tripple clamps 5 - 8 m.m. Here they are at the stock setting of 0 m.m.
And now with the forks raised 7 m.m.
