After tearing down my brand new unridden 450 to lube the linkage I found the first downside of the aluminum frame. The frame blocks hand and visual access to the rear carb/airboot joint. How do you get the airboot back on the rear of the carb more easily? I got it back on but it wasn't fun. Anyone come up with a better reinstall method.

yeah i used a small amount of lube on the air boot and intalled the single bolt on the top of the subframe (not tight) and the lower it down whilst pushing on the boot abit from the bottom as it contacts the carb just wiggle it abit and it will silde straight on.

I took the great suggestion of removing the top shock bolt to ease installing the subframe and airbox boot to the rear of the carb. I put a 2x4 under the rear wheel, removed the bolt, and allowed the shock to lower about 1". That little extra wiggle room allowed for an easy line up and install of the airboot to the carb. Before, the shock was literally in the way. In addition, with the shock loose, you can pivot it back and see that the boot is all the way on the carb looking from the right side of the bike. I'm also going to move the carb's right rear side vent hose routing to the right front float bowl screw. This will allow better visual check of the airboot / carb junction.

Some observations I made during my disassembly/grease/torque session:
The rear linkage and swingarm pivot bearings had minimal grease. Also, you'll need a 19mm crows foot to torque the bottom linkage bolt to the frame. The frame blocks socket access. The steering head bearings had barely a swipe of grease as well. Tearing her down and lubing the bearings seems almost madatory with these new bikes.

Compared to my 05 yz450, the fitment/quality/alignment of components is a leap forward. I am very pleased with the component quality on this new bike.
Also, you N. Texans can thank me for bringing the much needed rain with the purchase of my new 450 this weekend. Next weekend's dirt should be great!

Make certain that clamp is completely loose. Also helps to remove shock.
