    Not sure you get the reference :). Anyway, it was fun, plus sometimes it's the simple solutions that are the best.

    base it all on the KISS principle. Works for me because of my dumbness.

    In this case it's also the thinking mans choice. It'd be about the same mass in alloy without lots of time milling bits out. So it works well :).

    Awesome work, loving the footpegs, looking forward to seeing this thing 'live'. Much for me to learn from!

    a few in the build queue in front of it.......but seeing your GT so close to stinking out the burbs.......its tempting to bump it up a spot or 4.

    :cool:

    Or, you know, you could give it to me and I'll film an episode of Australian Chopper: Chops Edition based around it.

    You know it makes sense :D

    hahahaahahhah Australian Chopper and my RD350B ?? well funny you should ask. Here is one I prepared earlier.......

    [​IMG]

    @Gosling1 on his first big road bike. RD350B. This photo was taken in 1980 at my parents place. Don't be hatin' on the Windsor Smith boots hipsters !! they were cool as phuck. Ditto the feax-leather 'gauntlets' - everyone who wanted to be hard-core - wore those back then.

    Fog light and Fiamm air horns were also de-riguer for the complete outlaw ensemble.

    Yes - I knew it made sense :ridgy

    Hahaha. The funny thing is not only am I posted, I'm also doing work. Plus I just bought some more little bits and pieces to get the GT sorted. Think I should have pillion pegs next time I get out there :).

    So, tiny parts are always the cornerstones of getting these builds right.

    [​IMG]

    Steering stem bolt in stainless, washer to suit, and an appropriate magnetic bolt for the speedo pickup.

    Still working out the wiring stuff so I can put in an order for loom tubing, appropriately coloured wires, and get it ready to fire up :).

    Life developments got in the way of me getting more done on this project for the last little while, but, I had a free day on Sunday and squared away a few more niggley bits. Lots more to do and it's rapidly looking like a project that'll be registered more in time for my birthday (April) next year rather than Christmas like I originally hoped. Oh well.

    Rear brake lever shenanigans
    ------------------------------------
    Covered above is my new fancy blacksmithed rearsets. This necessitated a bit more work on the rear brake lever. Where I left off I needed to find a way to retain the brake lever from moving along the foot peg and still look pretty factory. I originally wanted to use a roll pin but decided that might not cope with the shear forces involved.

    [​IMG]

    Decided to go with an option where I use a bolt that holds a small steel ring, that then sits against an aluminium bushing to then sit against a brass bushing setup. That way if the gear lever gets sloppy I can replace the bronze bushings, also, if I do crash I can more easily remove and replace the rear brake lever and all that stuff.

    [​IMG]

    Chuck an M6 tap through it so I can fit a decent sized bolt. Steel foot peg => no power tapping here, all just brute strength... ok not really, a sharp and good tap makes all of the difference.

    [​IMG]

    Tapped for M6; I do love how high quality you can get with decent hand tools and a bit of technique.

    Plus lube. Lots of lube.

    [​IMG]
    I spun up this steel collar that's bang on the right diameter for the foot peg, and was too thick. That way I could file it down on each side so it perfectly fitted the bolt into it, minimising the slop on the brake lever.

    [​IMG]

    Collar and retaining bolt all installed. Nice countersunk bolt makes all of the difference.

    [​IMG]

    Had to bend up a new rear brake rod using stainless rod to make this all work. A bit trickier to do with the rear brake lever now this far back and up compared to the original spot, but, it works. Cut the stock foot peg rubber down a shade and it's all perfect.

    Left hand side footpeg stuff
    ----------------------------------

    [​IMG]

    Left hand peg much easier; the rearsets I made were designed so they perfectly took the stock footpeg rubbers for a slightly more stock look. I can always spin down some aluminium bar to make fancy foot pegs and bolt them on later if I don't like this arrangement.

    [​IMG]

    I use everything I can on this project. The levers and pegs were originally out of a custom kit I bought (pre having access to a lathe) and I repurposed the pegs to make pillion pegs. Little known rule: if you have 2 seats on your bike, you're meant to have 2 sets of footpegs for roadworthy. Best not to give anyone at Dickson something to argue with... so I tapped the mounting holes out to suit the rear shock mounts et voilĂ  I have pillion pegs. Originally on this model they mounted to the exhaust hangers but on later GT250s they actually mounted the pillion pegs to the rear swingarm anyway so this isn't too different.

    Coil wiring
    -------------
    [​IMG]

    Having never played with dynatek silicone wires this was interesting to work out how the hell one hooks it all up but it's all done, complete with the correct resistance plug caps for this model & a fairly factory look. Tucks the ignition wires up nice and neatly into the frame and looked pretty sweet with the tank back on.

    Speedo pickup
    -----------------
    [​IMG]

    Acewell uses a magnetic speedo pickup, so we whipped up a nice little bracket to hang it off the bottom of the fork. Will paint bracket etc all blaaaaaaack when it's finalised and I'll need to work out a cunning way to hide the wiring running up the fork leg but it's one more job completed.

    Other stuff
    -------------
    Made a new friend:

    Charlie gave me some tips and let me loose on a cube of aluminium plate so I could practise my TIGging:
