    First time was around 30K miles, but the bike was running just fine when I changed it. Kept the old one.

    Next time about 50K and that's the one that's in it now, plus I've got the two for spares.

    I've not had any issues with the filter so far and will likely just use this one until it gives problems, then put one of the others on before buying a new one.

    But then again I'm a cheap bastard.

    I have 60K KMs (about 40K miles) and I am still on the original filter/regulator. I do travel with a new spare.

    I did put a filter on the fuel tank breather line.

    Thanks for the reply. I will tell my buddy to hold off on the headgasket for a while. We are all most into winter now and him holding off won't hurt a thing. looking forward to the ride report. Ride it hard and lets hope everything stays together.

    Wish you'd posted this before for me! :evil I didn't know about that thread....it's exactly what I'm going through.

    Have to compare his measurements to mine now! :wink:

    Well, while my measurements don't match with michnus, our specifications do! michnus said the "Enduro 693-01" bar was the closest to his handlebars, and I suspect he was right. It's just his measurements don't tell it that way.

    michnus measure: 760 160 -- --- 100 ---
    Renthal 693-01: 790 101 71 120 73 200
    My measurements: 795 110 70 135 85 210

    Just for interest sake, Renthal do an Enduro "High" which could be an option:
    Renthal 613-01: 830 130 95 130 75 192

    That's SO much work to save such a minimal amount of money I can't see why you'd do it.

    The new heated grips cost me $58USD and came with a really nice 5 position switch.

    Contrast that with the labor of cutting the old bars, cutting the new bars, weakening the new bars by cutting them/drilling holes, paying for the machine shop and all the extra time involved...

    Plus now if a heated grip goes out I can get a replacement anywhere and it'll plug right in.

    Well, it depends on the perspective, and not a question of saving money

    Firstly the BMW method of running the wiring through the bars is silly, on the LHS there is no good reason for it, on the right it is simply poor switch cluster design and it is resolved on the new G models

    In terms of the mounts though, I and others wanted to maintain the bar ends and allow the stock hand guards and doing the inserts enables that. The other aspect is that the hand guard mounts on some of the aftermarket ones are known to slip around and that can affect levers when the guard is hit

    BMW learnt that lesson with the 1200GS and had to do a recall, the 650 stock guards can be affected the same way

    On mine the mounts are locked in place and they cant twist out of place

    For me there was no great machining expense and very little time in running up the mounts and I still have the old BMW mounts to extract from the old bars if I want to, all that is very easy. There is no weakening of the bars with one hole in the centre between the clamps

    As for the heated grip controller, I have continuously variable grips, no switches or high/low, just a knob on the LHS, no power loss on partial heat and somewhere over 95% efficiency

    Soldering in a momentary on/off switch got the ABS working the right way.

    I messed around with the throttle control, trimmed things slightly, moved the control inboard on the bars more and lubed them. Probably about 85% better now, but still doesn't snap back the way it did before...

    Got some new bling for the Dakar this week. Going to try Tubliss system on the ol girl. Most of my bicycles are tubeless, actually, all of my off road ones are so i am very comfortable with using systems like this. Why not in a moto?
    First, had a rear wheel rebuilt by Woody's Wheelworks in Denver from a stock to an 18" so I could run the system as well as have a bit more clearance on the rocks around here.
    Nice wheel and system:

    I'm running the T63 tires I have been running for a while. 130/80-18 size. Setting up the Tubliss system was a breeze actually. Found it easier than trying to stuff a heavy duty tube in and not pinch it with your irons. Just follow the directions to a T and life is good. I even dismounted it to see how difficult it was. Again, surprisingly easy! Easier than a tube. Also, the Excel rim I had built up was way easy to unseat compared to the stock BMW rim. Tip, use lots of Amoral or polish to mount the Tubliss system and tons of soapy water for the tire and seating.

    Mounted:

    Pic of the stock 17" with T63 and the 18" with T63 tire. will be about 1/2" more clearance on the bike. Sweet.

    Presto chango over the brake rotor and sprocket carrier with some new cush rubbers and mounted on the bike.

    As of this morning, no pressure was lost overnight :clap Can't wait to get her on the road, er, off road and try it out!!!! :D

    [​IMG]

    Oh, and I put the Tubliss in the front wheel as well. :evil

    SuperTrapp. Love it. Nice rumble and tuneable by adding or removing discs.

    Maybe when you cut the end off the throttle tube there was some plastic bits that got between the two tubes casing some friction?
    Only other thing, I used it have Acerbis hand guards on my bike and they had an insert in the bar that you then threaded the end bolt into like you do with the HDB guards and if you over tightened the bolt, it would swell the the bar just enough to make the throttle sticky.
    I have had the HDB set up for many years now and it is different as it threads right into the bar (at least on mine) and have not had a problem.

    The throttle/grip spins freely on the bar, so no grunge in there. I rode the bike today and it snaps back enough that you don't notice it, so I'm not going to mess with it any further.

    Yep, I have a Supertrapp on my bike too, sounds great, but is a little loud.

    Another question, I bought the Pro Taper KX HI bars because they were supposed to be the same height as stock, well, turns out they're around 3/4-1" lower than stock. Doh! Now the bars are too low, even with my Rox Risers.

    What other 7/8" bars out there are the same height as our stock ones?

    When we prepared a friends' Dakar for the road test (Tüv) after it sat for almost a year, we stumbled upon a sticky throttle, as well.

    We ended up applying a good amount of WD40 to the spring on the throttle body,
    fast forward a couple hours and it worked perfectly again.

    Might be worth a try.

    My immediate thought (from personal experience) is that the hose blows off becuase of increased coolant pressure. The pressure, sadly, is caused by exhaust escaping throught the headgasket into the collant channel in the cylinder block. The root cause is most likely a warped head and the problem will not be permanently fixed before the head is removed and skimmed level.

    My coolant kept blowing out the overflow tank, not the hose, but since you've replaced everything else, you're pretty much out of options... The good news is that since I skimmed the head it's been running perfectly for 3 summers now.
