    I'm alright. It's too bad the seat wasn't on my chest. That would have been easy. Instead I had the engine/frame on my chest.

    The chain is not the original. It's a Primary Drive X-ring w/ clip master link.

    +1. Not that much torque to rip the chain off. Just make sure the closed part of the link is going forward, so if you clip something, it doesn't bump it off. I've been in lots of mud, rocks, water, & other miscellaneous terrain, & not had a clip come off.. yet..

    Working on bikes can be dangerous... back when I had my Ninja 250R, I had it up on the rear stand and was behind the bike moving it in the garage when it slipped off one of the swingarm spools and fell over on my leg... the corner of the license plate made a nice inch long pretty deep gash just above my knee and I had to go to the ER for 6 stitches. Had a long ride planned that day and needless to say it didn't happen. I'm much more careful working on the bike nowadays!

    Last week I mounted up a MT-43 rear on my WR-R. Love the tire so far, except that today I had a flat and had a helluva time fixing it solo on the roadside. But that's another story.

    Anyway, tomorrow I'm going to buy a new tube and my question is what kind to buy? Regular, Heavy Duty, or Extra Heavy Duty?

    I was told I should run 12-14 psi on the street with this tire and that higher pressure would cause premature wear in the middle. I split the difference and set it at 13 psi cold (Accugage that's always been spot on).

    When I mounted it I used a tube that had a patch on it on the outside (facing the tire tread). It's one that had gotten a puncture from a finishing nail that I'd patched last year and had done fine for over 6K miles in two D606s running 25-30 psi most of the time for the road.

    I know I should have put in a new one, but it was all I had at the time and held up fine for the first three rides - around 400 miles.

    Anyway, today coming back home after about 75 miles at 55-60 on backroads the rear got squirmy and when I pulled over it was flat. When I got the tube out the leak was at the patch and the patch had gotten so hot it looked discolored and melted. Didn't look at all that way when I put it in last week.

    So, I'm assuming that the low pressure + Alabama summertime + sustained road speeds is generating mega-heat, right?

    I've always read that you don't want to run the really heavy duty tubes running low pressure on the road due to heat buildup, but I want a more robust tube to avoid pinch flats. What to do?

    What are you guys running in the MT-43s?

    Thanks!

    Got the master link off. Just took some fiddling with a very small and then small screwdriver. It's like the X-rings were suctioning the plate on. All is well now though.

    Yet another good word for the WRR to add with the thousands of others in this thread. Took a ride near Red & White Mountain a couple days ago (North of Vail, CO) and the bike performed flawlessly. I'm a noob at tougher offroad riding and usually stick to simple forest roads and the like, but this ride definitely was a learning experience in that arena. Had to make a few bypasses around downed trees and had to drag the bike over logs and roots - extremely thankful this bike is light enough to manhandle around obstacles. Needless to say my previous '01 KLR 650 would have NEVER gotten me back into the areas I was able to go with the WRR. The KLR's weight and gearing would have had me defeated in a very short amount of time. Concerning the roads and area it is a very beautiful area and is covered with single track and ATV trails. For you Colorado folk, if you've never been up this way you def need to check it out. Great place for camping too.

    On the ride I made a few tactical errors and while riding alone, went down trails that were very steep (in my inexperienced eyes anyway) and that I didn't have a hope of riding bike up again. In one situation I was faced with a hill that I had a hard time riding down (it was even hard to walk down it without losing your footing) and expected there to be no way back up again. I considered power walking the bike up the hill, cutting through the forest and switch-backing my way up again, or follow the ever dwindling trail and get hopelessly stuck even farther into the woods. Well I didn't like any of those options so I decided I'd just make a run for the hill and even if I only made it halfway up, I'd only have to drag the bike up the last half. So I backed up a good little ways and ran for the hill, with surprise and joy the little blue WRR drug me up the hill without a single bit of fuss! I hear some people complain about low end power on the WRR but multiple times throughout the day it was more than enough to save me from steep, slick, and rocky sections of road and to keep me out of trouble. With a heavier bike or one with inadequate gearing I would probably still be in those woods somewhere...

    On the way back home I hit I-70 for about 20 miles and the WRR comfortably rocketed me along at 75mph without a fuss either. Talk about a versatile bike!

    And for those interested the Wolfman Enduro bags worked very well and without a hitch. The D606's were excellent and pulled me through everything I threw at them. No complaints whatsoever!

    My nickname for the WRR: The little blue bike that could....

    I run Bridgestone Ultra Heavy Duty tubes......and generally run the front and rear around 10PSI.....sometime lower in the back......I've run for days at sustained 50-60+ speeds at ~10 PSI, like last years Kings of the West ride, without issue....

    Here's a video one of the riders shot....it's from the bottom of the gorge up to the rock that juts out in the trail.......I was leading the group......you can hear me on the radio once I reached the rock saying, "the risk/reward isn't there for me......I'm walking it around this rock" :lol3........the trail goes another ~half mile from there and eventually turns up right above the gorge......

    One more question...

    Looking at the Bridgestone Ultra HD tubes, I find two sizes in 18" tubes - 100/100 and 110/100. Which ones are you running in the MT-43s?

    Thanks for putting them up :thumb

    Ha! Nice trail...that's like the kind of trails I mostly ride....of course, I also have loose and arthritic SI joints from the couple of times I found things not going as planned....still the challenge is the fun, what better way to spend time, eh? At least that trail doesn't have trees below that stop the fall in an overly abrupt manner.:huh

    I ordered the small "triangle" rack from Automotive Machine yesterday. Asked about bolt length, was told 'every bike varies':huh. Not too worried about that though, seems like a CYA statement and I'm pretty sure M6x70mm will work. However, I forgot to ask if the mount holes are countersunk or not, so I need to know whether to order flat head (countersunk) or buttonhead bolts. Anybody with one of these "triangle" racks want to enlighten me? Their website shows different hardware on the different racks, so I want to confirm how they were actually drilled.

    Nice find on this video! Being professionally done, you'd think it might be for a commercial, but it's way to good to be a commercial.

    Even on relatively smooth roads, notice those factory-paid guys don't dare put their butts down on the seat at speed! They know all about the stock rear shock and what it can doooooo....LOL....
