    I’m not sure if I should laugh or cry at that! I’m not sure what I’m going to do if the cylinder is out of spec and beyond repair. I suppose just get another one. Anyway... I have some news. Upon closer inspection I’ve found 2 letters facing UP on the second piston ring. No markings on the top ring though.

    I also went through my carb again. A lot of people have speculated an overly rich condition. Main jet is a 140, pilot jet is a 42.5, main air jet is 100. Mixture screw is 1.5 turns out. Needle isn’t worn, but I did shim it and remove the snorkel in the last 85 miles. Float o rings are brand new and I usually average low to mid 40’s for fuel economy. So I don’t think it’s running rich, but again I can’t say how it ran for the first 12k miles since I didn’t own it during that time.

    Cylinder, head, and stock piston are going to the machine shop tomorrow morning. Given the condition of the top end, I’m a little worried about what shape the bottom end is in... Anyway If I hear back that the cylinder is serviceable I’ll place the order with procycle. Really hoping that all this work fixes the smoking issue. The clutch cover gasket was torn in a few places and I found some old RTV sealant so someone has definitely been in here before. Cylinder head bolts were also extremely tight I needed a breaker bar to get them off. Not sure if that’s from the factory or not.

    I swear I feel a 3rd year failure coming just as soon as everything’s back together and fixed.

    I was just messing with you. You are going through the 5 stages of grief. You are at number 4. :lol3 It will all be ok. Honestly everything looks better than I expected. You should see some of the stuff I take apart. I look at it and wonder how to make chicken salad out of chicken shit. You will get it back together, worry about reliability for about a month, then you will be back to having fun.

    Fix it, ride the fuck out of it, have a great time, and just deal with whatever comes along next. All part of mechanical things... or things with tits...:lol2

    Wow... At least mine still has all its valve seats! That picture would fit in just great at reddit.com/r/justrolledintotheshop

    While I have everything apart I think I’m going to grind down the header weld. Removing clutch to inspect tomorrow, then an oil change for the WR250r before riding Saturday. I never thought I’d have a day when my Suzuki gave me more problems than my VW!

    Every DR650 project comes to that critical part of the algorithm where you have to dial 541-688-9543 or else you missed a step.

    We stopped to try to help these folks out. They were so excited to hear than I had a pump! As I dug into my tool kit to get it, I said “yer not gona like my pump”.

    With regard to grinding the weld on the header; don’t go crazy on that. For one thing, I don’t think it really makes a difference you will ever notice, the other thing is that the weld needs some support from the bead for strength and vibration resistance. I ground mine. Mine cracked right there too. It took it a while.

    What a great experience! I didn’t know Ducati had. 950cc vs of the Multistrada. I’ve been on the 1200s and think they are very nice but kinda too much power and everything wise which seems the thing these days: more is better, too much is just right.

    Hehehe.....that's going to be a pretty good work out to fill that tire.

    I once complained to a local mechanic about the POS hand pump that came stock, attached to the frame under the seat of my 1971 R75/5. I told him it took forever and a day on the side of the road, to pump my tire up. He said, ' did you get it inflated?' I said 'yes, but...' He said, 'What are you complaining about then? It worked. ' :nod

    The stock tool kit on those old BMWs, by the way, was awesome. I still have most of those tools.

    I dunno about you blokes, but I am in my 50's and I have a crook back. I like to travel alone, but I need help when it comes to lifting my bike up after an off.

    I found this, Certainly something that could help lift a fully loaded DR650

    It's a great idea but it is heavy and something else to haul around. :dunno
    There is at least one other product available to lift a bike.
    I agree the DR is a beast to pick up. :baldy



    I think a great product would be inflatable air bags mounted on each side of the bike with an onboard electric compressor.

    When you find yourself on the ground, just turn the engine off, then push the button to inflate that side airbag to lift the bike up to where you can easily tip it all the way up.
    The airbags wouldn't have to be very large, or lift the bike very much.
    A BMW or HD is a good bit easier to lift because they don't lay flat on the ground like our bikes do.
    A good heavy duty fabric (Kevlar?) bag with the thin inflatable rubber airbag inside would be trick.
    Perhaps a plastic outside shell that clips to the bike to contain the deflated bag like a side cover?
    The airbag would be mounted to the bike sides below the seat...

    Hmmm, maybe a winter shop project? :hmmmmm



    Nah, I have several bike builds to work on that are much more fun :ricky

    Best I could do on short notice. The BULL BAG. We used these in the 1970's & 80's during 24 hour long off paved road rallying. Could push a 4x4 out of a snowbank. More effective as the vehicle got smaller. Just needs connection to exhaust pipe (adapter?).
