    Well, I think we're getting a little carried away here. My wife might, but the bikes get the majority of my attention so I doubt she would encourage said behavior by providing more parts lol.

    WR450F TIPS MODS & REVIEWS

    with the power they put out they can't be as bulletproof as a tractor like the DRZ, but generally they go a lot longer than comparable high performance bikes in terms of rebuilds, valve adjustments etc. personally i preferred the steel frame models (pre 2007) as they were barely any heavier and it was much easier accessing the carby and engine without that bulky alloy frame...

    I have seen a lot more drz failures then WR. I'm with you on the steel frame though. Maintenance was waaaaay easier.

    YZ timing! Retarded my WR exhaust cam one tooth for more power. Have to mill down the decompression pin to keep your estart though!

    This is a FREE mod. You need to have an aftermarket or YZ exhaust to get the extra power though, it improves exhaust scavenging by opening the exhaust valves at a different time.

    I noticed extra snap throughout the powerband.

    valves have moved... probably not a great thing, but the bike has 150+ hard hours and this is the first time they needed to be adjusted

    pin out it measures .940

    dremeled down .040 or 1mm.. then rounded and sanded smooth with a few grades of sandpaper to a shine. Now put it back in, only 1 tooth retarded (make sure you use a white pen to line up everything!!!)

    back together, greasing bolts (swingarm bolt) if you haven't ever greased yours, do it. there are pics on the xr400 section of a guy who resorted to cutting off his entire swingarm from a frozen bolt.

    Excellent post and pics. The swing arm bolt is often neglected.

    this: $15 off ebay

    It has 4 wires.. green and black w/ white strip are not used.
    The other two are used with the brown and solid pink wire.

    Zip tied to the speedo box mount. nice and snug

    switched on

    I converted the whole bike to DC... so I added a relay to turn all the accessories and lights on (or enable them to be on) when the ignition switch is turned on
    This is a mini relay. I discovered a handful of them at a junk yard in a ford car. I think I got half a dozen for a dollar. Also in that mess of wire is a phone/gps charger adaptor hardwired in to power my android GPS running MyTrails.

    key turned on.. headlight comes on, tail light.. power for acc comes on... the big black and red on/off on the right is power for my heated grips.

    n16ht5,

    Would you explain a little about the DC conversion? What is the AC originally for and why don't you need it? What gain do you get over the stock DC?

    (Talk slow, I'm not real smart about electricty...:huh)

    Was also curious what you guys are using? Seems like my normal bulbs keep burning out on the bumpy trails. I also have the hi and low switch on my bike so looking for something heavy duty with good light output. Thanks in advance.

    The seat is made by seat concepts. The poster of that bike is the guy you need to talk to if you want to buy one (mxbundy). I love the seat I got from him. Check him out in the vendors section. Believe it's free shipping for forum members too.
