Hi SD,

I don't think it will be anywhere near finished this year and not sure CBOTY is for competition bikes.

I got the front disc back from being machined down to 5mm today. Apparently it took them nearly 3 1/2 hours to do the job and they requested that they never be brought another one :D . The cost was "ouch" and I have since been fiddling with the Caliper, mounting plate juxtaposition to get the Hub in the centre of the forks with the disc running through the centre line of the caliper slot. A task that had me sweating because every thing is so tight. The disc has to miss the fork leg and at the same time not foul the spokes whilst getting the centre line of the hub in the centre of the forks. I had to re-mount the caliper on the other side of the mounting plate and space the disc out by 6mm (using temporary washers) but I think I got there (fingers crossed). Next step is getting appropriate spacers made up and lacing a WM2 alloy rim to the hub and hope the caliper will clear the spokes. This build is getting complicated, sheesh.

I took the oil tank along to a welder tonight, very handily he lives 3 minutes away. Should be ready tomorrow.

Cheers Geoff

Getting the front end to look quite motorcycley with the addition of the Throttle, Brake & Clutch. The Brake and Clutch are both Magura items in-line with the classic requirement.

A nice man in a van brought me a set of Mikuni VM 38-9 carbs today:

I also got the seat firmly bolted on to the frame, I might hoist myself up onto bike tomorrow and get the controls adjusted to my liking (If you catch me making Brrm-Brrm noises I shall deny everything :lol: )

Cheers Geoff

My tame machinist also has a small project on the go.

I asked if he could knock me up a c/r 6 speed gear cluster and he told me to *%$* off.

It's looking Ace Zun - it may be a complex build but it'll be worth it. If you sit on it and make brrm, brrm noises, we won't tell.

CBOTY does have a category for competition bikes for sure as there was a Yamaha crosser in there a few years bike - tidy bike even tho the guy was racing at weekends. Might be worth putting in for it even so, it'd get my vote and Hooli's too I'm sure.

Looks like you've an SV in there too.

Hi SD,

My build schedule won't be in time for CBOTY. I have an aim to track test it at the end of March next year at Pembury at a North Glouc. run test day. Even that will be a "stretch target" in project management terms :D . It seems common with the cottage industry side of racing, where a lot of specialist skills and capability resides, that you add 6 months to any expected delivery schedule. These guys are very busy it seems and are usually one-man-bands.

The fully commercial side of things is pretty good, I just received a nice set of custom cut rear sprockets from B&C Express:

Excellent quality and service.

Cheers Geoff

The machining does look nice in the pics - can't tell what the metal quality is like of course.

I remember those cheapo sprockets I bought for my Honda in Nigeria :( and the chain was pretty rubbish too

Got a little more done in the shape of a Splash Guard for the rear wheel. Still needs a bit of a finish and polish but it fits nice and snugly.

Image

Last week I got my tame machinist to bore a hole for the rear wheel spindle in the caliper carrier, shame I set the centre punch mark in the place for an 11" disc instead of the 9" disc that's actually fitted :oops: . I like drilling and filing so Mk2 will be fabricated this week (damn). At least the torque arm could be trial fitted (no adjustments needed) and I think I now have the measurements for getting the spacers for the hub and wheel build.

Image

I also got my "race" rubber. 90/90x18 Avon AM26 front and 110/80x18 Avon AM22 rear. Coo, the stuff is sticky just sitting in the workshop. I have chosen a Scitsu rev counter, mainly because it's just about the only one on the market. Powered by a non-replaceable (factory only) rechargeable battery which IMHO is commercial blackmail. Please note the ultra-light "stealth" rim fitted to the Maxton front end :D

Cheers Geoff

My fingers are getting a bit sore with all this filing, what I need is a vertical Mill :D . Rear brake pedal just about finished, pivots on a needle roller bearing. I still need to rig up some kind of return spring:

Image

I hit the "Buy it" button for a Powerdynamo electronic CDI racing ignition today. It seems as if it should be easy to set up, I hope it generates well at bump starting speeds my aging legs won't take too much abuse pushing it around the paddock :lol:

Cheers Geoff
