    That bike is coming together nice!!

    You're Welcome!! But I'm sure you'll will come up with some unique chain set-up solution. Why would you simply copy someone else's work??

    Your SL350 is looking good, nice job! :D

    When we get to Mexico, I'd like to take a closer look at your exhaust, the CNC retainers look like some I found being made here in the Portland area and was hoping to use on my SL350 MX bike. Are you using the sleeve type retainers to hold the head pipes in (similar to stock) or springs?

    Those are left over from my order to MotoCapelinni. I couldn't use them on my roadracer with the Jemco pipe. Look on their website to check them out.

    Worked on the skid plate today. Since we are on a little time crunch, we decided to make an existing skid plate that we had, work. After digging through a pile of skidplates, we found an aftermarket one that looked like it might work. So we cut it in half and melted the two halves together with a strip of scrap aluminum. Here is a pic of said sad skid plate.

    Keep in mind I am learning how to TIG so this is the only weld that I can show, the others are just too ugly to be shown on the internet. Here is a closeup for your enjoyment.

    LC asked about the pipe. The flanges are like my dad said, motocappilini, and they use the stock setup with the two halves in the head. I took a pic of the pipe today after we pulled it off the bike. I know there is a science to building these pipes. The only science used was more of a, "yeah that should work". We will see how that pans out. Anyway here is the pic.

    I am thinking of wrapping it with the heat stuff for the race to help keep the heat down. Hopefully I will have time to do that before the race.

    Kinda feel like I am in an episode of american chopper, with the looming deadline and all:rofl.

    I will keep plodding along thanks for following my build.

    Not much to report today. Finished skid plate mount and tore bike down for paint.

    Spent a couple of hours chasing down hoses and fittings for oil cooler. Had to weld on some fittings to the oil cooler because I could not find the banjo fittings I wanted. I had some help with the welding on the oil cooler, my friend Danny is a much better welder than I am, so the cooler turned out well. I will post up some pics once I get it together and working.

    Looks like we might have some hats for sale if anyone is interested. Should have some pics of them next day or so.

    Thanks for the heads up on motocappelinni, went to their website today and there are lots of cool bits for the old twins. If I just had an extra 20K I could build my dream bike; a 250 lb, 50 hp nickle framed SL350 motocross bike, then we'd show those AHRMA guys a thing or two! Looking forward to visiting with you when we get to Mexico. :D

    Sitting here 800 miles from the bike I have been doing the only thing I can which is riding as much as possible. I got the chance to ride a friend of a friend's excellent private track yesterday for about 4 hours and it was fantastic. We got a bit of rain on Saturday and the track was freshly groomed hero dirt. It felt good to sit in the saddle even if it wasn't Baja goodness. I have also been doing an hour of cardio every day just to get my lungs in shape.

    Oh and John sent me a spy shot of the bike with the newly reconstructed seat before he tore it back down for paint...... looks pretty retro rad (but not pretty yet) to me.... Can't wait to see this vintage machine come together, it really will be a sight once she is completed.

    Hey Matt:wave.

    Talked to Owen today, the guy helping me with the bike, and he said the bike should be together and running next week. I will be able to get some pics of it then.

    i have been working on our chase rig as well

    This is what I started with, pics when I get it out of the garage.

    Now if you could get that fifth wheel in the background hooked up to that bad boy, we could really do it up right and proper!!!

    Maybe a mobile concession stand or T-bar :lol3:lol3:lol3

    Nice job!!

    Got back Sunday night from Tulare, Ca where they had to cancel the AVDRA national mx race because of rain & flooding. Kind of a bummer to drive 600 miles one way for nothing. One thing though that was kind of cool. Gene Fetty & Bill Silverthorn showed up & we got to meet & talk to them. Gene & Bill won the 1970 Baja 500 on a Husky & then won it again in 1972 on a Honda XL250. Bill said they blew up a lot of engines before they got it right. He said they wound up with a 340. Only way I know to do that is to use an 80 mm piston with a stroker crank. I asked Gene if they were pretty beat up after the race from those short travel bikes. He said when you win, you don't feel a thing. Great guys. At Tulare,their bikes were Huskies that looked like they had come out of a museum. One had a titanium frame. They were outlawed in the '70s but just as well since they were brittle & would crack & break. These guys are in their early 70's & race 50+ expert class. Told them about John Jr.'s bike & upcoming race. They didn't say much. Probably figured he was crazy!! :lol3

    We had the great privilege of meeting them both last summer at the AHRMA Classic at the farm in Chehalis. I was running the SL350 in the trials competition and they did think we were crazy! But they still signed the gas tank....

    Then Gene went to his truck to show us the some photos of that XL250 that they ran in Baja..

    Hey OC what are you doing admiring their chase vehicle, you have TWO sweet chase vehichles following your bike. :lol3 OK maybe they aren't as cool but we make up for it with personality. Now get back to your own thread and give us an up date on the D100. :amazon


    Hey, LAMEco Racing how's your bike coming along? Isn't it time for some more of those spy camera pictures?

    Laced up an excell rim up front and an xl 250 aluminum rim on the rear. Chain and sprockets showed up yesterday. Should have chain stuff sorted soon and hope to have it running by end of week.
