Scooterotica

Ok, I'm working on my anti dive system, I changed the axel for an Innocenti one and have limited side play down to the clearence within the bearing. I've done away with the speedo drive housing and replaced with a bearing. Any spacing issues from the hub to the carrier plate bearing can be sorted with a spacer. Still not quite sure what to do on the other side where the carrier plate meets the fork link. Will a spacer that just protudes from the carrier plate be ok?

So now I'm looking into the tie bar pivots, which is better a flanged oilite bush or a sperical bearing? Below are some progress photos.

rose joints for me

spacer will be fine m8 and use rose joints for bar

Regarding the postion of the caliper on the disc, the static brake pad side should be just off the rotor, or should the gap between both pads be even off the rotor?

I'm leaning toward the former...

Set it up even, but the caliper floats so it will move.

Nice work Frank, and surprisingly close to my version of the caliper bracket (though yours is rather neater).

As you know from previous pm's Frank, I opted for a four pit opposed caliper. This just seems like an easy route to centralising the caliper. It does need more clearance behind the disc, as the four pot caliper is simply wider.

My tie rod is based around rose-joints acquired from the steering tie-rods of a kart. They are cheap, but you need an M8 lefthand thread tap for one end.



Whilst you have taken the decision to junk the speedo drive, have you done so in order to keep the caliper on the RHS? After trying to accommodate the speedo drive and the caliper on the RHS, I suddenly realised that there was no need to keep the caliper on the RHS when you are using an anti-dive set-up. If the caliper bracket is intended to pivot about the axle, then the second fixing on the RHS suspension link has no role in the brakes. It can still be used as part of the cut-down speedo drive.

I could not accommodate all the compoenents for the front brake until the caliper found its way to the LHS, though I guess this is of little comfort if you have already welded the top fixing for the tie rod onto the RHS fork leg.

Here is a photo of the brake during construction (rotated for your benefit)

Hi Martin,
I like your work. And to keep things simple for me it's all on the RHS, I'm using a 'far east pressure cast hub'.

oh, and choke cable works a treat!, now I just need a new choke assembly.

yamaha caliper martin?

R1 mono-bloc thingies. I think they also fitted them to FZR models. The finished item:

Martin, your hose looks a little tight..
