    Guess I’m ready to pull the trigger on these crossover? parts. I used the 2010 XC-W450 as the selected bike.

    Rear caliper rebuild kit

    If they are a direct fit, I’ll notify AllBalls. :dunno

    Perfect fit. Bleeding out all the air was challenging. Took more time and attempts than I’m accustomed to.

    I am glad that worked out for you!

    Just changed my swingarm bearings and sprockets. Interesting adventure.

    Wasn’t willing to buy the L sealed bearing that is made specifically for BMW. Saved a bit buying from a local bearing supply house. Made a gasket from an inner tube for the L stainless threaded cap thingy. Left a weep hole in the bottom so water can escape and loaded both sides with grease. Certainly as effective as the R side rubber cap. Sorry I didn’t take pics.

    Hi DirtyDog,
    Is one able to use a grease gun on the swingarm shaft? I seem to remember reading somewhere that you simply remove the screws on either end and pump it full of grease...? Is that right?
    Thanks

    Yes. There are no zerks, but if you hold a grease gun firmly against it, you can build enough pressure to inject grease. The shaft is bored from both ends (but solid in the middle. There is a weep hole a few inches from each end which supplies grease inside the counter sprocket sleeve/shaft behind the seal. Make sense?

    I bought a needle adaptor for my greasegun from my local car parts shop.
    Wasn't that expensive and works very well.

    Great suggestion. Will likely make things easier (and cleaner).

    Rode the 450 for the first time since I replaced bearings and sprockets. Decided I’d take the Safari tank off for a while since I don’t have any longer light-DS rides planned, just trail riding.

    With the 15/51 gearing, half-worn tractionator (recently re-mounted), and less front-end weight... this bike is a wheelie monster!

    Gonna carve out some singletrack time in the next few days and I’m looking forward to riding sand dunes (in high-power mode with a paddle tire :eekers) in a few weeks.

    Sounds good! I fitted a set of Tractionator Desert H/T's yesterday. I'm looking forward to testing them on the weekend. I've ordered a 15 front sprocket as the previous owner was running a 13/48!
    To switch to high power mode do you just need to unplug the bridging plug that connects the two wires or is the other way round where the two wires need to be connected through the plug?

    Yeah, I believe 15 is stock. Having a tiny counter sprocket accelerates the wear. Rear sprocket sizes are not super available for this bike, it seems. We’ll see how the 15/51 combo does on trails. I found the 14/45 (on the bike when I got it) to be reasonable on faster, dry, sandy/rocky trails, but it wasn’t right for tight, rocky, muddy, woods.

    For high-power mode, I wired a circular dashboard push switch to the vacant spot on the dash. You can’t change it on the fly... the bike has to be shut down (and the headlight off?:scratch) before you can switch it and re-start the bike.

    Thanks for the pics. I'll look at doing the same. Is power mode open circuit on the two wires?

    Closed circuit (dongle in place or switch set to ON) is high power mode.

    Was supposed to ride today, but had family obligations. Hope to hit trails again tomorrow. I’m way out of shape.

    Rode at Jandebeur’s today (off-road park). Building some conditioning and skills. Rode the advanced single track 5x and my last 2 loops were faster and flawless, as I focused on keeping my head up and looking ahead. Rode the vintage MX and intermediate MX courses numerous times, but mostly spent time on the trails. Rode the whole thing on high-power mode.

    Did an endo into the creek once because I hesitated and the front wheel went in a deep chasm. Second time, I jumped it and landed with a squirm in the mushy creek bed, which compromised my exit line and ended in a spectacular biff (pictured below).

    If I could somehow do this often, I might actually be in shape for the OkieSprint series this spring.

    Rehabbing from elbow surgery and training for the inaugural Okie Sprint race series in May. :deal

    Just thought I’d drop in with some work I’ve done since last time. Changed the CS sprocket from the 14t to the 15t. (Very happy with this decrease in cruising rpm) While I was at it I replaced the bearing on the left hand side, very glad I did this. Right side roller bearing looking pristine, so filled everything with grease and reassembled. Replaced the exhaust header-pipe crush gasket as well. I’ve also fitted a keyed ignition that is working out wonderfully, now if this rain would stop! 32EE8B58-DE05-4789-8CB7-33F690547DC7.jpeg EEAEDEB5-16AF-40A8-8EE6-FA6EF005EFCD.jpeg
