    The shift linkage ended up on a less than perfect angle after shifting the centre point about 100mm. It worked, just...but was shit. 

    So I machined up some stainless rod to extend the length, as hey let's be honest, a little more length is high on most guys wish list:

    I then tapped an M8 thread through it, and used about 30mm of M8 threaded rod to connect it to the existing linkage. This added ~60mm in length and i made the rest up by having the threads out a bit on the rod ends.

    Boom!!

    Now the linkage has near 1:1 give or take mechanical advantage, so about as positive as you could get in a set up like this.

    how does it work now? Perfectly...Fuck yeah!!

    Maybe that's where the "harley stomp" shift technique comes from? 

     

    Must be getting pretty close to rideable 

    Maybe? My leg already looks like this, so I'm keen to try retain it and not take it off the foot peg more than necessary

    The wiring is the big job. I started it, way back in L4 lockdown, but its not something I enjoy doing. Just gotta get over myself and do it. Its all there, no excuses.

    The forward controls looked awesome, I figured someone must have done some kind of R&D on them, or at least tried them out, but whoever designed these was a fucktard!!

    Seriously, the shifter arm had its pivot center about 100mm behind the foot peg. The arm was only about 150mm long, so 150mm - 100mm = 50mm of room to squeeze your foot in.

    ○Basically you had to lift up with the shifter here.

    ○Then, you had to lift your entire foot off the peg and lift it up and over the shifter, put you entire foot on top of the shifter to shift down the gear, with no heel contact on the peg at all, your foot literally floating in thin air with only your toes sitting on top of the shifter as you brake and down shift!!!

    Most forward controls have the shifter share the same pivot centre as the foot peg. I checked all my measurements and think I can get away wwith moving them very close together, as the arm is quite long.

    Re engineering the mounts.

    Now it work more like this:

    20201224_201520.jpg.636f45e5cb6f42261f75c621baa022cc.jpg

    Only the tip of your toes has to flip around the shifter, maintaining heel contact all the time on the footpeg.

    Much better, it actually works now. You can simply pivot your foot, maintaining contact with the foot peg and shift gears up or down, just like a real motorcycle should.

    I'm happy now, much better.

    Its growing on me, its actually a very solid bike under the 20 layers of rattle can paint jobs hiding its past, like an old hooker smeared in makeup and cheap perfume.

    I bobbed the tail to tidy it up, looks much better already. All I did was unbolt shit. Then added some bar end mirrors i had left over from projects past.

    Today I purchased a motorcycle dolly, because I've always wanted one.

    I'm not sure why, as apparently motorcycles come with their own wheels and aren't that hard to shift on your own...who knew?? But hey, I achieved a life goal of owning a motorcycle dolly, so I'm still calling it a win!!

    Okay, slight u-turn...

    20201221_222543.thumb.jpg.880023b5bd14df5dbce28424a2a76d28.jpg

    Some v-twin Japanese nostalgia to add to the collection. Tho the cunt who sold it to me did a runner with a box containing the wiring loom, headlight and a heap of good stuff promised in the sale. Long story, but just yet another sad reminder that in life you're going end up doing business with a cunt every now and then.

    Anyway, the bike has good bones. I have steel, a grinder and a welder, plus about 100hrs this week alone of watching YouTube on cafe racers...so let's get past that small hurdle and start planning a cool build.

    No time frames, no budget (As in zero).

    Small project today. Something I've always wanted, but they sell for ridiculous money (plus postage from UK on top!!).

    So I made one, basically cost $20 for the oil can (with oil, that I'll pour into my mower, then replace with 2T oil).

    I knew that old belt that broke on me would get a second chance. It did me well for about 12 years wearing it most days.

    Turns out even a cripple can change an oil seal...

    Its was leaking so much, the rear brakes no longer worked. I used degreaser and cleaned it all out. I didn't wash it with water inside the rear hub because I didn'twant to contaminate the gearbox oil etc, fingers crossed that doesn't do bad things? I just whipped it down with a rag best I could?

    I then sanded the brake surfaces on the drum and the pads, put it all back together and boom...brakes work hard out, easily locks up and does skids.
