    I forgot if there was a dedicated thread for "As Seen On TV" or "Dirt Bike Sightings On TV Or In Movies" but I just caught this one on an old Jan '74 episode of Hawaii 5-0. Cracked me up because it was another one of those "rides up on a 4-stroke but the soundtrack is of a 2-stroke" scenes. I always thought that the continuity expert was supposed to catch things like that. It's a somewhat younger Peter Strauss riding it.

    I tried replying (twice) right after I posted that after looking at the pic again it was possible that the cable is not even attached. I couldn't really tell, but thought that might be possible and therefor would not have been the problem. If that was the case then... NEXT?! Paul

    What about the cable attachment to the arm itself? Looks like the cable is already rubbing the case, and would then be trying to pull the lever and pivot rod(?) upward. Should the cable be attached to, and pivoting from the top of the arm instead? Don't know anything about these bikes specifically. Just doesn't look right from here. Paul Ahh, or is the cable even attached at this point? Looking at the pic again after I posted I realized that might be the case and it's simply sitting there under the arm. Paul

    YZ 125 fresh rebuild compression

    Here's the link Need some help. Luckily it was recent and I had not deleted it yet.

    YZ 125 fresh rebuild compression

    There is an excellent article here just recently about just this subject. And coincidentally enough it was written by Wiseco to explain their recommendation for break-in. In it they said that, while there are many ways to break in a new piston/cylinder/ring assembly, but this is what they recommended. Reading through it, it did make a lot of sense. The main criteria was monitored heat cycles. I'm not going to try to quote it here, so no way to mis-interpret or mis-quote them. Check it out if you can find it. I'll see if I can find the link, but it was in one of the e-mail newsletters just a few days ago. Not sure if that necessarily means that the article is also new, or someone just wanted to bring it to light again. I almost never check the dates on stuff like that, and often don't even notice what forum they're in. Just like to read. Paul

    New Old Dude

    All of the above and then some for the time spent in the dirt! But it's a crap-ton (SAE/Metric hybrid engineering terminology in use here) of fun so enjoy it while your knees let you. Protect those joints! Miss the old drag strip. The Scramble days, drag days, Speedway bike days and any other days at what became Baylands Raceway, only to fall to the onslaught of progress and is now an Auto Mall. Oh well... Did you hang out at Cal Kart on First St/Monterey Road back in the day too? Been meaning to do a "then and now" pictorial of all the places we've lost, in the old-school riding thread, but it's hard to get to most of the old haunts for the traffic! Looks like you moved almost as far away as you could though, so not sure if you've seen the old haunts lately or not. Enjoy the ride. Wherever it starts, and wherever it takes you. Paul

    Cylinder head gasket fitment?

    Thanks Erik. I know a manufacturer has to count fractions of a penny, but seemingly simple solutions that get ignored or shot down are annoying. Look forward to hearing what they have to say to your e-mail. Paul

    rosin core in bottom end

    Glad you got it out. No other happy outcome as far as I was concerned when I started reading. Even with something soft-ish like solder So the first thing I did while reading was try to determine from the pic or from what you were saying whether it was a 2 or a 4. I've never heard of this test, never heard of using solder, and don't know every bike intimately enough to decide just from the pic 100% it was indeed a 2-stroke. I thought it might be, but wasn't sure. I was also obviously not noting the forum we were in from clicking on the link in the e-mail. Hardly ever note that. Just interested in the discussions. So many changes to the bikes and the tech over the years and I have not kept up with the details obviously. But all I knew was that, if a 2-stroke, you HAD to get it out of there. A buddy had a '71 Suzuki 250 that a wrist pin clip had fallen into. While I was heading over to my house to get magnets, needle nose and anything else that might help, he decided to just throw it together and run it. Because, hey, it's down at the bottom where it can't get into any trouble. Right? When I got back he'd just push-started it and was heading down the street. Thirty seconds later he was pushing it back. Yes, a metal clip is a LOT harder than a bit of solder I'm sure, but that sucker literally got sucked up from bottom in the crankcase to top and bounced around the combustion chamber for a bit. Made some nice grooves in the piston and cylinder wall, and lots of cute dimples and divots in the cylinder head and piston. I already knew the potential outcome from listening to my dad, but apparently he needed to learn the hard way. So for me at least, I was glad to read you'd got it out first. Paul

    dirt rider tits up

    Guess I'm part of the problem too. Last time I had any kind of an extended subscription to a bike magazine was my beloved Cycle mag! Can't remember when they went under (late seventies, early eighties?) but I kept getting busier and busier, with less and less time to read a whole mag before the next one showed up. And speaking of print media, about the only thing our local newspaper did in the way of trying to future-proof themselves (even though they didn't know it at the time) was to actually buy the land they built their business on. Did it back when land was still a couple hundred dollars an acre, and sold it in the last couple of years for some obscene amount that lets them keep paying their rapidly dwindling pool of employees. Being still in print, they just had the opportunity to write about a 900 square foot house in Sunnyvale (just four or five miles as the crow flies from them) that just sold for something along the lines of $2388.00 per sg. ft.!!! https://www.mercurynews.com/2018/03/02/sunnyvale-home-shatters-new-record-with-enormous-price-tag/ Fun fun, for those that own. Dilly dilly! Paul

    Cylinder head gasket fitment?

    Shame they couldn't just make a tiny tweak in the design at least so that the one in the lower pic is sticking out 1/4" to the left and simply sits in the pocket of the casting. I agree that as long as it's only touching the upper and not the lower casting it's not going to cause any mischief. But a slight change would have precluded even the perception of one. Paul

    Needle won’t go in bearing?

    It's always the last one, right? I agree with what's been said so far, but as a last resort before pulling it out and replacing it entirely, what about pulling all the needle rollers out and making sure there isn't just a tiny bit of debris in there taking up valuable space. It's a fiddly job for sure, but it might be worth 10 minutes of your time to pull, clean, and re-install them just to see if it's truly distorted, or just needs some grit removed. Good luck whichever hole you go down! Paul

    Sealant Burnt on to Exhaust

    Oh, and that jacket just needs some patches and to be kept in a place of honor! Need to keep using that one for years. Great story starter for sure. Paul

    Sealant Burnt on to Exhaust

    Great follow up! Thanks Glad you went back and I'm sure they appreciated the pizza (almost as much as the honesty!) too. The first thing I thought when I saw the preview pic in an e-mail was that a boot got a little too intimate with your pipe. But the colors were off and even the material colors looked odd. At that point your thought of sealant seemed the most reasonable. Glad to know first impressions are still reasonably accurate ones! Paul
  15. Did you guys follow the link? It's quite an assortment of dollies. Maybe I missed something (maybe the link was not originally there?), but I thought it was pretty funny. Paul
