Project Bike: 2009 Yamaha YZ450F
Nine months ago, I caught a bug which resulted in me purchasing my first MX bike in 15 years (I'm 40 y/o now). With 20 "gentle" hours on the bike, and my confidence pretty high that I'm still a competent rider, it's time to get serious! At 6'4", 240 lbs, this bike doesn't fit...but that's about to change!
Over the next two weeks I'm tackling the following upgrades/maintenance in one big shot:
1) Handle bar swap (stock to Renthal Fatbar RC High)
2) Seat swap (stock to SDG tall)
3) Front tire swap (from stock 742FA to Geomax MX51)
4) Rear tire swap (from stock 756 to Geomax MX51)
5) Oil change
6) Fork spring swap (from stock .47 to .50)
7) Shock spring swap (from stock 5.5 to 6.2)
8) Swingarm and linkage re-grease! (a little nervous about this one!)
I'm going to prep my garage tonight by cleaning, installing a larger work surface, vice and improved lighting.
I've ordered fork and tire changing tools...so I should be good to go there.
I've been hunting TT and YouTube for how-to's for the past week, and I've found some good information. That reference material, along with my service manual hopefully will see me through.
Wish me luck...and if you have any tips/tricks, or any suggestions of additional things I should do while I'm at it, please fire away! I know alot of you guys have the equivalent of a PhD in motorbikology...and as always, I can't thank you enough for your guidance!
I love my bike ...and I think she loves me too!
I'll try to post some updates/pics as I progress. May be some good info for other novices looking to step up their game!

Since you're in the neighborhood, re-grease your head tube bearings.

The seat swap is a piece of cake.
The tire changes you might need a little help on. Maybe get a friend to show you in person or something.
Oil changing will be easy.
The forks springs are going to be a little tricky.
The shock spring will be really easy.
And greasing the swing arm and linkage will be pretty easy as well, just a lot of work to get to the parts.
So I mean you really aren't dealing with too much even for a beginner. Just take your time and do not rush. If you run into trouble go take a brake for an hour or so. Good luck.

- The fork cartridge bleed procedure
- The correct way to reassemble the damper rods to the rebound adjuster

Fork cartridge bleeding and damper rod/rebound adjuster assembly...thank you, I will look specifically for information concerning these steps.
Re-grease your head tube bearings = will do. When the bike was a few hours old, the lower bearing pooped all over my pretty white fender and stained it...will definately hit it.
Tires - Again, I've found a solid how-to video, and have ordered 2 Tusk irons/spoons and a tire bead tool. I don't have a stand, but I may be able to borrow one. Hoping I can avoid killing the tubes.
Torque wrench - If I don't buy one, I'll borrow.
I appreciate guys. <---Edit: heh...how about "I appeciate IT guys"...not guys in general

That sounded pretty gay (not that there's anything wrong with that)...

I've always just used a 5 gallon bucket for tires.

Yeah...definately need to learn how to check the valves. I'll have to get one of my buds to give me a hands on with that...

Take it back. In the first place, the bike calls for Yamaha S1, not the old 01 oil. In the second place, it's way too expensive (and S1 costs more) for no better than it is, and especially considering that it doesn't last any longer than it does.
Also picked up Yamaha 01 fork oil ...
Amsoil Shock Therapy is a much better choice in a conventional oil, and Maxima, Motul, and a number of others are good choices as well.
The absolute best is 215.VM2.K5 from SMART Performance. It's a different approach, and works exceptionally well.

Think I'll stick with the conventional oil this time around. Once I get fork servicing down, I'll get a bit more exotic! The 215.VM2.K5 boasts some pretty amazing benefits...would love to eventually give it a try. Sounds expensive!

#5. If you want to try something different, use #5 in the cartridge, and use the #10 in the outer chamber. This will probably allow you to use a slightly lower oil level in the outers (say 330 instead of 350cc per side) for an overall plusher feel without bottoming.
Okay folks...I see the Amsoil Shock Therapy available in light #5 and medium #10 weights. Preference?
