BREAKING NEWS: Novice Wrench Turner to Attempt Multiple Maintenance/Upgrade Projects Simultaneously 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!
