After years of an '00 426 and a couple months of playing on an '05 YZ250, I just landed an '06 YZ450F in the garage. The kid I bought it off of was a tool. Fueling was all wrong and the suspension damping and rebound were 'turned off' if that were possible. Bottom line is that I am going to do a full service to the bike, including greasing all the bearings (triples, swingarm, etc.) and checking the valves to have some knowns. I'm not a racer, just a weekend warrior out to have fun...and be a little faster than my riding buddies. Its pretty much a stocker with some bling like a sub-mount Scott's damper system and the Boysen AP cover (both coming off). I have never ridden with a damper before and don't know if it makes a difference in the desert trails (washes and single track technical stuff). I'm going to get the bike set up and then ride for a month or so without it...then install it to see if I can feel a difference. If not, it will get sold. Tonight I am starting the process of the labor of love. I got the carb off to UPS and on the way to ziptyracing.com for the carb mod 'kit' (the $160 version). I was undecided until the plastic hot-start cable nut snapped uff during disassembly. Heh - now its an easy decision. I'm doing this because I know the previous owner was messing with the carb and I want to have the pro's go through it. I'm decent at jetting, but as I become older time is more valuable and jetting on the trail doesn't seem fun any more. It may still need some jetting, but it will be pretty damn close. I've also decided not to send the forks or the shock out for revalving yet. I've read great things about the capability of the stock system so I plan on spending some time with the adjustments to see if I can tune them to my liking. This is a helluva lot easier than messing with jetting. If I have the time, I'll probably swap out fork seals and oil just because. As for the rest: Devol skid plate & frame guards on the way MRD-Racing full exhaust system with S/A (S/A req'd here) on the way IMS desert tank on the way New chain & gearing on the way - 13/53 Cycra pro-bends just installed Magnetic oil drain plug (from zipty) Hour meter on the way Gripper seat cover on the way Dunlop 739's on the way Rekluse z-start pro likely will be ordered tomorrow All of the above except the full exhaust system & carb mod kit are things that I have done to my 426 and I am very pleased with those add-ons. TT was an excellent resource with the AP set-screw, JamesNOW mod, and the '01 clutch upgrade. I know, I should just ride the thing, but I have some down time at the moment with business travel so what better time to order stuff. Besides, the bike with the list above (less the rubber) will total about $5200. Anything I'm missing??? Yeah, I know I kinda shot the wad but its fun. Now if I only get a smokin' deal on an 18" rear wheel for better desert rubber selection.
