    Here's where we left off;
    [​IMG]

    Grinding rivets to separate fender from bracket;

    [​IMG]

    Separated, note how bent up bracket is, straightening it will be easier after reliefs are cut out for upper fork legs;
    [​IMG]

    Marked for relief cuts;
    [​IMG]

    One side cut (using 4" cutoff wheel);
    [​IMG]

    Both sides cut and semi finished and straightened;
    [​IMG]

    Fender bracket trial fit on forks, so far so good. Note trials tire donated and mounted by Luke:D;
    [​IMG]

    Fender test fit on modified bracket (hard to believe this came from a CB650);
    [​IMG]

    Liking this!
    [​IMG]

    Time to fit a rear fender (lucky for me Luke had TWO CB650 front fenders), lines give rough idea of proposed cut, will leave lower portion intact;
    [​IMG]

    [​IMG]

    [​IMG]

    Trimmed damaged section of chrome fender off just below rear seat, drilled one hole and bolted it all back together for initial fit;
    [​IMG]

    Not bad for a 3/4 a$$ effort! :lol3

    Saturday morning I got out in the shop early, wanted to make progress on the trials bike before the Seahawks game and then the plan was to head South to Salem for the indoor short track as soon as the football game was over. I'm sure glad things are slowing down as I get older. :lol3

    After installing the rear fender (bobbed the worst of the two CB650 fenders Luke had) I planned to take the better of the two fenders, grind out the rivets and install onto the mounting bracket modifed from the first fender. After more grinding and finish work, I riveted the second fender to the modifed bracket and installed on the fork legs. It seemed simple enough, but it took a couple of hours.

    The finished product;
    [​IMG]

    At Salem, three generations of dirt track racers: Harry Fisher, Rex Fisher (former national number #12) and Davis Fisher, rising star;
    [​IMG]

    Davis dominated the racing Saturday night and finished each race with a back-stretch wheelie. Cool! :clap

    Sunday, it was watching more football, this time my second favorite team, the Broncos. After that, back to the shop to try and get a little more done.

    Time to change the crappy back tire (that's not mud); :eek1
    [​IMG]

    The tire was an ancient retread knobby, it was so stiff it had been ridden by my daughter for years without air (and thanks to the two rim-locks);
    [​IMG]

    My efforts to remove the stiff carcass was damaging the rim, so I decided to get serious with my trusty recip saw;
    [​IMG]

    And now we're ready for a new tire and tube. Here is the used tire Luke offered, but I discovered a missing spoke so that will have to be fixed before mounting the tire; :huh
    [​IMG]

    As soon as the back tire is installed, I'll swap out motors and get it running. I need to wrap up the majority of this project by the weekend, so I can get back on the motorhome and get it ready to roll this spring. It's never boring around here! :D

    My new ebay spokes arrived, so time to get crackin'!

    Replacing the missing spoke;
    [​IMG]

    And then the damaged spoke;
    [​IMG]

    All fixed;
    [​IMG]

    And the @!$#%^$&*%^!!! tire mounted;
    [​IMG]

    Unlike Loud Al who is a tire changing champion, I am terrible at the process. :eek1 But perseverance won the day and the tire was mounted successfully and for once no holes punched in the tube. :D

    Next up is to service the wheel bearings, mount the wheel and tire and then swap out the motor. Soon the little TL will be ready for action.

    After I've had chance to try trials out for a few events, some time in the future I'm considering perhaps building a 350 twin trials bike, like OC did a couple years ago, but take it a little further. Any thoughts? :ear

    Yep, I have a thought. Get your head examined. Something's not right. :evil

    Last night we made good progress on the TL125, while I finished up installation of the rear wheel, Luke began pulling the old motor.

    We decided to get a shot of us wearing our matching insulated coveralls. Since we got these we are going through a lot less propane and firewood! Note matching bottles of home brew in our pockets (courtesy of Ken Fisher and Grateful Deaf's Brewing) :lol3

    After about an hour of thrashing, wheel and new motor are installed. Hope to have it running this weekend. :D

    Those coveralls are awful clean. What's with that? :lol3

    Last weekend I was asking where Luke was and now I at least know he's still alive.

    I hope I get to see you guys at the D100. I sure miss my Outta Sight Buddies. :cry

    We are planning to be there, not sure yet if the dual sport SL350 will be ready, but as the projects get caught up, we'll get started on it and do our best to make that happen. :D

    Once you have insulated coveralls, you'll wonder why you waited so long! :lol3

    These should also be great for hanging around the fire pit at the D100 and other chilly events! :wink:

    Yesterday was spent with little red doing domestic stuff, so today I started early and got with the program.

    First up was making the TL125 a runner. Sorted out all the engine fasteners, got it all snugged up in the frame, then cleaned the carb, attached all the cables, exhaust, ignition, tank and seat.

    Almost ready;

    Filled it with fuel, turned on the petcock, applied the choke and 3 kicks later she was purring right along. Took it for a quick ride that made my day. Here she is after the first ride, still lots of tuning and TLC needing to be done, but at least it's a runner;
    [​IMG]

    Will park it for now and get the TTR250 ready for spring rides, as well as getting started on the SL350 projects. Spent the rest of the day servicing the transmission and fixing oil leaks on Nellie, no point having the bikes ready if the support vehicle isn't up to the task! :D

    LC Garage, check AHRMA NW http://www.ahrmanw.com/aMotocross.htm events are close at hand...
    I am going to ride at Terrebonne, LeMay, Hannegen and Rattlers Run. Unfortunately thatÂ’s about as much as I can fit into a year. What about you?

    Hi Dave! We will be at Terrebonne and Big K Ranch, plan to do the trials and MX. Have never done trials, so will be squeezing in as much practice as time allows. Luke has some trials experience so he is guiding my noob efforts. :D

    Last night I put our motor home Nellie back together one more time, and I sure hope this is the last time I have to pull the doghouse before the D100. It is an '86 Ford E350 class C that we bought about 1.5 years ago, that had fairly low miles @ 99k and ran decent, but even then I knew it needed tuning and carb overhaul. Since then, I've pulled the doghouse numerous times (not fun), given it a full tune up, carb overhaul, trans service and a multitude of small repairs, but it never did run quite right. I finally discovered the egr plate under the carb had a blown gasket, but it had been blown so long the manifold casting had become eroded and would not support a new gasket. not having the time or money to replace the manifold right now, I decided to block off the egr valve ports for now and while it was apart also replaced the old Holley (that I'd overhauled but had already blow the power valve, grrrr) with a new Edelbrock. Until I can replace the manifold and get the egr functional again, I have the distributor advance running off manifold vacuum (instead of ported vacuum) to help combat detonation or pinging. While I had it apart, I thought it would be prudent to install plug wires and a new coil. Good thing! When I pulled the coil off and removed the wiring/horse shoe clip, discovered what may have been giving us some of our drive-ability issues. The 12 volt power wire had been rubbed/frayed/burnt down to only a few strands of wire, it was a wonder it even ran as well as it did. So repaired the harness, cleaned and re-wrapped all under-hood wires and added split loom for protection. Installed new coil, installed plug wires and used high heat boot socks and also split loom on wires, they are about as protected as I can make them. Checked timing, set at a conservative 8 degrees initial and also verified operation of vacuum and mechanical advance. This is all it gets for now, have to get bikes and other gear ready, hoping it runs well and gets decent mileage. Next winter I'm planning to install an aluminum intake and make the egr functional again and also will install a 429 timing set that will put cam timing back where it belongs (the 460 uses retarded timing to increase exhaust temperature for emissions) and is supposed to increase power and fuel mpg. Anyway, just want to get back to the bikes, prepping and riding! :lol3

    As for the bikes, the TL125 won't take a lot to finish up, the SL350 wheels are finished and ready to be picked up and took the TTR250 out for a small ride last week and it is running beautiful, not much to do for prep on the D100 except getting some seat time and sorting out gear. :D

    New 12 tooth countershaft sprocket for TL125. Immediately discovered the retainer does not fit. :huh

    [​IMG]

    Old sprocket and retainer, compared with new sprocket and backyard retainer method (e-clip). Washer is being used to shim between sprocket and countershaft seal, and to reduce lateral movement of sprocket.

    [​IMG]

    Installed

    [​IMG]

    Both vintage bikes eagerly awaiting further attention.

    Luke and I are going trail riding Saturday, time to get some miles under our belts before heading north to race in D100. :D

    I'm looking forward to seeing the two of you at the D100.
