With you on that one Beach, my racebike has (supposedly) R6 forks in it that are 42mm diameter yet my tracker project has R6 forks that are 44mm diameter.
You're bike is coming up really well, shame you don't live in Oz as I'd be happy to look after your welding and machining issues if you needed it.

Hey Pete, thanx for the kind words - yea - just imagine if all us guys could pool our talents !!!

My forks were always queried by the guys on the KZ750 twin sites ... but nobody could actually say which model they came from. I wasn't bothered as I'd always intended to use the 4LS Grimeca and wire spoked wheel.

Another good weekend.

The fork clamp fits ! And the new paddock stand bobbins have also been fitted.

We have almost finalised the side panels, just a bit more aesthetic tweaking then we can cut the shape. They will attach to and follow the shape of the seat to give a bit of a curve .... nothing worse that flat panels !!

I've also bought the switch panel for the NOS, fuel and other functions, plus a start panel.

Will your paddock stand fit between the bobbins/spools and the rear axle nut? On some of our race bikes we have to drill out the axle to push a steel rod through for a rear stand.

Side panels are usually the hardest parts to style because they have to work with tank shape, seat shape and angles of the frame rails.  I got lucky on the phat trakka and was able to take stock GT750 side covers, slim them down a couple of inches each and then moved them forwards.  After that I was able to make new ones out of carbon fiber that look stock and work with all the surrounding shapes.

On yours the manx "tank" and G50 seat are different shapes/styles so it's a bit more challenging.  More CAD in your future.  Stock up on Cardboard.  There's never too much.  I still do a lot of design printing pictures and using typo correction tape or cutting white labels and sticking them on to cover up parts that need to be re-styled.  Pens and labels and cardboard are cheaper and faster than mo9lds and resin and carbon twill.

Because our bike is narrower than modern machinery we do have good clearance. HOWEVER, it will all be assembled and trialed properly next week !!

I agree on the side panels ... the top will follow the line of the G50 seat curve and as it will be attached through so all the alloy edges will be under the glass lip. that point it should pull the panel into a nice soft curve - then it will dive under the Manx "tank". Originally I planned for a G50 tank cover, but it was too narrow to do the job I wanted.

We'll know next week when the panels are mocked up in CAD and then thin hardboard which hopefully will give us the same sort of curvature as alloy [ 1.5mm ]

BTW - the CAD footrest plate is NOT the finished shape or style, ::) that was done merely to put the hardpoints in their relevant position in space after I'd sat on the bike "assuming the position".

I'm planning on something with a gentle upward arch and obviously much smaller and hopefully aesthetically pleasing in 10mm alloy plate.

We are very fortunate here in Redditch as there are a couple of companies specialising in offcut / overun materials - alloy, brass, stainless, MS etc. Tube, bar, plate, sheet and some oddball stuff - hexagon etc. Everything seems to be 5 or 10 !!! So best to bundle more than the bits you want [ without taking the piss ] and you get a super bargain deal as well as some future stock !! ;)

Teazer. thanx to your feedback I'm definitely looking at a traditional Silver. There are a couple of likely candidates [ car colours ] and when I finally decide, I'll get a sampler tin of each colour and probably use the seat as the test piece. Maybe then a front to rear red stripe [s ] in the frame colour, but definitely Manx style pinstriping on the tank and panels.

The rolling chassis should be completed, torn down and re-sprayed ready for final assembly before my pal is of to his property in the US again.

I'll use that down time to make a start on the engine. 8)

Fork brace fitted - needs to be polished as and when.

Paddock stand bobbins fitted and P/Stand tested out for function - spot on and can remove rear wheel / spindle.

Side panel shape now patterned in CAD, final check of footrest position and then footrest mounts will be made [ 10mm alloy ]. The rear wheel spacers will be made up next week, and I'll get front rear/ spacers bright zinc plated.

A good weekend's work.

The seat has had it's final shaping glassed in and all the mounts double glassed. Once the glass has set we'll start the final surfacing with filler. Then it's off to the trimmers. Still undecided to use the Red or Black perforated Connolly hides.

Either way, there'll be contrasting Bentley Diamond double stitching.

The tank cover is also completed now - all brackets secured. Just need to do final outer surfacing and I'll shoot it in primer again.

The belly pan has proved a real headache, not least because it was not symetrical - and the fuel cell was !! All sorted now and mounting brackets glassed in.

Seat and side panels now mocked up. Just need to prep the seat for paint and then it's off to the trimmer to decide how we are going to make the upholstery. Looking at a seat pad and separate back pad initially. We'll mock it up and see what it looks like.

The side panel shape has been finalised now and we'll make it up in 1.2mm or 1.5mm alloy sheet. I want the top fixing to follow the gentle curve of the seat base - flat alloy doesn't look so good. The curve will be self formed once the fixings are installed.

Final work before a couple of days downtime.

The tank and seat are now properly mounted and all the fixings will be glassed in with gel flow coat over.

Next job to finalise the fitting of the fuel cell / belly pan and then we can complete the mock up for the fuel delivery pipes.
