    Took out some pistons today with little run time on them and a good example of ring contact.

    First picture you can see the dot on the second ring showing up. IMG_20180913_132256848.jpg

    In this picture the top ring is a D faced (or some call it a barrel face) Moly ring. The wear is in the center and doesn't go all the way to the edges.

    Second ring is a reverse taper. You cans see a light wear (shiny) mark on the bottom of the ring. That is the only part that touches the cylinder wall.

    I find US stuff has a dot showing up orientation. Foreign stuff often has a letter. Most I see have the letter "N". Not sure why N, maybe the non-US guys can chime in and break the code for me.

    Can't say I have. Mahle (Germans) put an "M" for Mahle on theirs. Most stuff they send to us dumb Americans also has "TOP" written out on it. They want to make sure. LOL

    Thanks for the flashback! Aside from the riders (Joel Robert was pretty awesome!) a couple of things struck me. First was the simplicity of it all. These riders were the creme-de-la-creme of the motocross world yet they were traveling in small conversion vans using trailers that would likely not pass most vehicle inspections today. Factory sponsorship back then likely consisted of a bike (if you were top tier) or maybe just tires and parts. Secondly, was the almost complete lack of safety equipment for both riders and spectators. Not even ear plugs and those bikes were LOUD. I suppose the full face helmet was yet to be "invented" in 1970. However, they were running those front of the front fender mud flaps we discussed the other day. ;-) Interesting.

    lotta Maico's in that vid. Maico got the holeshot in the first moto on the tape. I like the strategy of fish-tailing and knocking down as many competitors as possible right off the bat. :photog

    Oh, yeah...for you youngsters, when they mention the East German Gran Prix, There used to be 2 Germany's. East Germany and West Germany. :D

    Great seeing the likes of Mikkola, Hansen, Geboers, Pettersen & Robert. I read magazines of the day aspiring to be one of those guys. Where has the time gone?

    I just arrived back home last evening from accompanying three friends on the ride of a lifetime in the Alps. Averaged about 200 miles a day on rented bikes while running multiple mountain passes. Our original idea of "hey, with only that many miles we'll probably run some of these passes several times each day" quickly went out the window as we were whipped puppies by the end of each day. Wow, what a trip and my three-decades-long dream is now crossed off my bucket list.

    Came across this fellow from Germany during one break, his wife riding the well-traveled DR and him on his K100 sidecar rig. We both agreed that the DR's mantra of "simple and reliable" was hard to beat. I regret that I didn't get his name, but since he said he's on advrider: Hi if you see this, and it was great talking with you!

    My wheels for the week, and that engine sounds soo sweet as it quickly spools up to 9k RPM:

    A view from Stelvio Pass of what's to come after this break:

    If an Alps ride has ever interested you, do it! It felt like every twisty road ride I've ever taken was just training for this event, and the road culture over there (respect and courtesy among cars, motorcycles and bicycles) is something those of us in the US cannot even conceive of. **Sigh**

    I hope not. :lol3 I really don't care if people talk about it. I get a kick out of the fact we can talk for 3 days on little pieces of foam you roll up in your ear. :D It's what happens when we don't have anything DR related to go over. Some noob needs to buy the new and improved 2019 DR so we can start from scratch...again.

    I'm waiting for pictures from @StannisBaratheon where he made his cylinder a planter. :lol2:freaky

    I would like to generate some DR related content soon but looks like I'm going to need to trade it for a jet ski. Calling for 15" (38cm for the VERY Southern crowd) overnight Saturday. I live on a ridge but might not be able to go far until the water moves on down stream. I suspect it won't be that bad, the weather media hype machine is usually wrong.

    I have a generator to keep the beer cold, steaks in the freezer, and water and food for the dogs. I'm good. :D

    Your imagination.
    You're welcome. Glad you enjoyed it.


    I did spot a silver '69 Mustang at the East German round, and a red '57 chebby in Switzerland.

    For me, the entire thing was a total trip. Roger De Coster' name is mentioned in the final minutes of the video. Another major star for Suzuki, which reminds me of when he was asked why his TM' DNF'd during a moto. His reply was that the bike suffered an electrical issue, which is correct due to the fact that the frame snapped and sheared the coil.

    It's been a productive coupla days. Taking choicest bit from two barn DRs and making one goodun. Would never have thought I could begin to manage it (so far!) if not for the knowledge so eloquently shared here. Thank you gentlemen.
