Hi Kawa, its works and looks well, but I just dont think it looks period enough for the CR...

Anyway, super quick update:

To fit the GL1000 filler cap I need to make up a filler cap bezel to weld to the oiltank. 



Mocked one up in CAD, and sent it to print yesterday:





The reason for printing this is to test the design against the compression of the spring, before committing to turning/milling one in aluminium. Update on the fit tomorrow!

Cheers

Had a good wander around Stafford today! Met up with some good contacts, especially for the Yam project.

Also met up with a CR guru and purchased these bits:

Sand-cast side cover and fuel tap:












Venhill '888' quick action throttle:



The side cover is just a rough casting so needs a lot of loving, however apparently they were pretty poor when supplied new in the kit in the 1970s. I will trim off the gates and sprue, fly cut  a face seal and drill for bolting on. I would like to CNC my own one of these but that will have to go on the back burner for now.

The fuel tap, is ready for bolting on! I am still going to machine one of these though.

And the throttle, its a starting point. I will either run this as-is but stripped of the anodising, vibro-polished add with some period fastenings. Or I am going to make a new throttle as a replica of the original kit style one.

Cheers

Quick update on some very tiny details!

I have been looking for a more period style filler cap for the oil tank. The Monza is pretty and shiny but does not look that original, it is also difficult to open when the seat is in place. After seeing a CR kit bike with a filler cap on that closely resembles the GL1000 fuel cap that is what I have decided to go for:



Once this arrives I will make an aluminium neck to be welded to accept this cap. 


The other thing is the seat fasteners, the ones that came on the seat were not quite right, they looked ok but let down the rest of the seat in my opinion as they are too bulbous:



The Honda seat studs, found on the CB400F do the trick and make the seat look a little less bling as the studs are less polished:



It's the small things... :)

Cheers!

Quick update:

Repro master cylinder suitable to run the double disk arrived, fitted with the replica bolts, I also dropped the clutch lever on to have a look!








Got to do the mods to the master cylinder:
- Remove ridges
- Remove mirror mount
- Remove some casting marks
- Replace with a more original looking cap

I will also linish the tube weld back and paint these clip-ons black and finish them with a turned nylon end cap.

I should be picking up some goodies at the weekend for the CR  ;)

Cheers!

Here's a link to H2erics build, another fine piece of work, if I remember correctly he even had Magnesium sliders made!, could be some useful info in there for you 👍

Hi Mark,

Eric's thread is fantastic, and is a great reference point and source of inspiration! When I started thinking about the build it was this forum and that thread that made my mind up  :) I have been in touch with Eric via PM, a great help  ;D

Cheers,

Thanks, guys. When I committed to building a replica that was the plan; to build the bike to the highest standard, quality and detail that I can afford. Working away on these small details seems trivial but fingers crossed it will all come together  :)

Thanks Mark  :)

Hi all!

I am after an aftermarket simplified CB750 throttle assembly for my CR750 build, any suggestions would be greatly appreciated.

Thanks!

A quick bit of progress on the front brake splitter assembly design:



I still need to add some location grooves for the wire clip.

Cheers,

Quick update:

Parts together and ready for welding. A quick side-by-side shot with an original HRC part:







I think I am going to make a second set of these from a high grade of Aluminium, as soon as I am happy with the design and fit.

Cheers
