    Good to know for the future... new switch is in there and is staying :D

    Going to order a new coupling (?) so I don't have the dead zone... may not need it but I like tinkering and collecting free stickers from vendors.

    Planning on doing the following over the next few weeks:
    -Check valve clearances
    -Check compression/leakdown
    -Coolant flush
    -Front brake flush (also bleed the rear again since I didn't replace the copper crush washers and didn't do a great job yesterday)
    -Inspect carb (bike runs hot and pops quite a bit on decel. Also some surging at certain constant throttle settings. Looking into some of the recommended rejetting options and new rubber diaphragms)
    -Inspect air filter, maybe look at aftermarket options and a prefilter.
    -New fuel level sensor
    -SAS delete

    In general I'm just looking to get a sense for the condition of everything, and make some minor tweaks.

    Long term plan, and the reason Steve and I were attracted to these bikes, is the Trans-America Trail. Call me crazy for getting the SM but it is better than my psuedo-serious plan to take the Speed Triple. (Look up WestcoastWanderer on instagram, or the Motocorsa TerraCorsa Panigale). What does that mean? Certainly TKC70's at a minimum, probably TKC80s... or something similar. Probably an exhaust system, oil sump, and skid plate from a Super Enduro. If I can sell my two other bikes, I like some of the Rottweiler offerings (namely the 2-1 yoshi exhaust system and intake).

    Maybe I'll even find some time to ride the dang bike! I do enjoy having a bike with a "to-do" list. Makes riding more rewarding, in my opinion.

    Totally open to everyone's opinions on the above

    I don't want the down time it would take to get it powder coated orange. Maybe some orange wheel stickers!

    Brake rotor question for ya. I've tried searching here and found some info but still a little confused. I had a local mechanic guy swap the new Moose Racing steering bearing kit for me at 22k miles, this because I was beginning to feel some slight rubbing when turning at low speeds. Even if that wasn't the problem I wanted to go ahead get it done now. Mechanic said the stock bearings were in decent shape but lacking much grease. He went ahead and installed but said the issue I'm experiencing is likely the brake rotors as he said they are warped slightly. Last night at home I finally figured out how to get the front end up using my scissor jack and its associated arms/grabbers - or whatever you call those dohickeys. Anyhow, I noticed the front wheel is not turning freely. It will go about a half turn before stopping abruptly. While in the air I cleaned the buttons and used 1000 grit paper and cleaner on the rotors. To not much effect. Today I'll replace the pads and give the whole caliper area and such a good cleaning. If the rotors are warped they seem to be warped ever so slightly and I can't "see" the warp when passing the wheel around but that may be common. Any input here appreciated. I'm supposed to leave on Wednesday for about a 1500k mile trip. No time just yet to replace to the rotors before trip but thankfully, the warping (if that's what it is) is not overly intrusive just yet. Shoot, I can't even tell any pulsing when applying the brake.

    How about your wheel bearings? Pull the calipers and spin the wheel.

    I had a strange vibration at slow speeds when I pushed the bike around and so loosened off all the axle bolts. I made sure the axle was flush on the right fork leg. Then tightened it all up in the proper order. It worked. My next option was to loosen bolts on the yoke but didn't have to. Something to do with the alignment of the wheel with the calipers. I also did the disk buttons to no avail.

    Lou, if you're not feeling a pulsing or shuddering under braking then I doubt you have warped rotors. They're pretty obvious. Kind of a mechanical anti-lock that sucks. Try pushing the pads back in the calipers and spinning the wheel. If the rotor is bent you'll hear it touching the pads. Some of this is normal and that's why we have buttons.

    Otherwise, just pushing the pads back on occasion is good to keep the pistons loose and free. Make sure there is room in the master for the fluid to go when when you push the in. Also for when they get hot...topping off the master is a bad idea. Keep your fluid levels at about halfway between low and high.

    Thanks for the word, Chuck. Yeah, I have my doubts. The guy who said they felt like they were grabbing was actually not the mechanic himself but his helper. What I think is the helper guy just hasn't much experience on bikes with as strong a front brake as the 950 which has some of the best front brakes I've ever experienced on a bike. I cleaned the buttons, used 1000 grit sandpaper on the rotors, cleaned the calipers and reinstalled the pads which seem to have lots of pad left. When jacked the wheel turns more freely with the calipers off than on but that's nearly every bike I've ever owned as almost all of them with dual disc give some kind of mild resistance when spinning. Or at least they have for me. After this work I'll get some miles in on the bike and report back.

    I use the KTM SM tankbag, which is like an Adventure bag minus the rear pocket. It's a big bag but I'm used to it. Not sure if they're still available.

    Yes, the KTM tankbag works well, and I used it a lot on my 950, then more recently with the 990 tank fitted. It fits them both.

    They're still listed as available at the usual sources, but not sure if that means they have stock or need to order them, only to find they're no longer available...

    Cheers... Paul

    thanks. another quick question, are the sprockets on a smr the same as sm? doing a 520 conversion, and vortex has them for our bikes specifically, but drive systems also makes 520 sprockets but for a smr.

    That's a different bag, one with the rear pocket which may not work as well on the SM/SMR depending on where you sit and stuff. It will certainly work, but you may want to look at Wolfman, Giant Loop, Endurostan...most anything made for a sloping Adventure or Enduro type tank will work on our bikes.

    Yes I know, but the original shown in the pictures was deleted and replaced by this one a few years ago. I've had both and they work fine on the SM.

    My mechanical monkey skills are always tripping me up. So after a local mechanic guy told me my front rotors are slightly warped, and a 1500 mile trip on the horizon, I decided to pull the calipers, clean the rotors and the pads really well. I reinstalled everything and took the bike out for a spin. Maybe it was just me but I immediatly noticed the front brake lever travelling more before engaging. I zip tied it overnight thinking maybe some air got in the line but that didn't work. I pulled the right caliper and had what I thought was a Shazam! Aha, totally embarrassing moment where I realized that I somehow made the idiot mistake of installing one of the 4 pads backwards. Genius. :D But at least I thought I had discovered what may have been part of the lever travel problem somehow. Just to be sure I went ahead and bled brakes twice even after reinstalling the pads/calipers (in the correct order). Both times when I bled the brakes no air even remotely appeared in the line. Still seems to be travelling more than it did before stopping. Still stopping like a top when fully engaged but seems to take longer and almost back to the grip for wheel lock. Any ideas what could be happening? When I initially pulled the pads and cleaned it all up, I pumped the brake a little to get the piston further out to clean but I think I might have pushed it out too far. Everything went back into place fine but I wonder if I didn't muck something up with a seal or something below the piston. Anyhow, sorry this is such a rambling post. Shoot, I've overthought this now to the point of redundancy and have actually forgotten where in the world the brake lever engaged before all this started even :doh

    I am not much help with the brake issue but I made a similar mistake a few weeks ago. I was wanting to eliminate the mushy feel of my rear brake with new pads. I pulled the current pads off and they had a lot of life left in them. I chose to reinstall them but I could not figure out how the inside clip went in there. I went thru all kinds of pry bars, clamps and other devices to get it back in the correct location. Then like you said Shazam, there is a cut out in the caliper for it to go thru. I felt really stupid!

    Lou, is your lever firm when it engages the brakes, just closer to the grip or is it engaging the brakes but mushing back to the grip by the time you get to the good stuff?

    Either way, what I would do is remove all the fluid you can from the master cylinder, then push the pistons all the way back into their bores, then slowly pump them back up as you re-fill. There may be air trapped in the master.

    As per the tradition I've seen (at least up to where I am on page 330) lets bring this thread back to the top!

    Currently checking the valves on my SM. All valves on the rear cylinder are in spec (nearly 65k miles... not sure when Walter adjusted them last)... started moving the radiator to do the front cylinder before I ran out of daylight. Will finish up on Sunday when I return from a quick Maine vacation. Hopefully will have the bike running again early next week!
