Very nice!!!  8)

Did you clear coat the tank?  I've been thinking of going a similar route.

I see that one of your tappet covers is not finned like the others, loose one?  Also, are you still looking for the flanges? I may have some laying around.

If you get the chance could you take  a photo of how the seat mounts to the frame? Any idea on what kind of seat it is? I have a tank like yours in the post coming to me and have no idea how to secure it down (what do you use?) or what seat will fit.

Cheers
Andy

Andy,
I'm not sure what seat I will be using, I may make my own. The original had large heavy mountings and the fiberglass unit is made from very thick fiberglass making it way too heavy. The tank uses the standard rubber bungs at the front for mounting and  has a bobbin on the back that you tie down with bungee cord secured to the frame (have yet to work out where.

The tank is not finished yet, it needs polishing as the aluminium on one side is wet and dried following the repairs.

Well I finally managed to get the bike off the build table both my mate and I lifted it off the table with a fair bit of effort and a bit of cunning.
I put the oil filter in and filled her up with GTX and low and behold she started leaking. After a bit of tightening of one of the oil tank bolts, it now seems to be keeping it's precious liquids inside.

Did a few mockup pics with fairing, exhausts etc. Still undecided but definately do not like the tail piece.














Yuk

After a bit of photoshopping.

Bikini fairing without headlight screen. Which may prompt a different fairing.



And with headlight screen

That's an incredible looking bike!  I like the shape and stripes of the tail piece, just not the overall size.  And those Pipes are Awesome!  Did you create them yourself? and if you did, what material did you use (pipe Dia. thickness) and how did you bend the pipe?

Can't wait to see this one finished!

Ratchet, those pipes are Swarbrick 4 into 4 pipes for a CR750, I do not have the tools to make pipes like these.

http://www.swarbrick-racing.co.uk/

I think I may have problems getting the left hand pipes around the swinging arm mount but probs like this are what make these builds fun right?.............

I'm not sure whether I will make the seat unit myself or if I will use a moulded cowl. I think that it will be made out of aluminium though.

Bike awaiting pipe cutting & bending and design of footrest plates.



The chunk of aluminium that I am hoping to shape into a footrest plate.

Dude...Holy #$%*.  That's an amazing build. 

Love the colors and the polished bits and the style and the new rounded seat cowl (I know it's only photoshop @ this point but I totally agree w/you on it's shape.) and the.....  and the.....  ;D

Thanks guys.

Got stuck into the footrests today. went far enough and these still need work before I will be happy with them.


Having drawn out the size and shape


Took a while with a hacksaw


Hmm getting there, but I thought that it was still a bit chunky. GSXR 750 K6 footrests and brake lever. May turn up a more period footrest.



Drilling and fileing the inside hole.


Happier with that, will need a bit more work though and then polishing.



I also started bending the seat pan, here is the base piece of 2mm ally plate


Marking out the size and shape


Having bent the edges around a broom handle, I will leave the finishing off until I have made the seat hump using Blue foam as a mold and then laying glass fibre over it.


I also started polishing the tank. I'm using Nushine II which is designed for polishing Warbirds and Airbus's. It is amazing stuff and the finest polish brings it up to mirror finish. I have a fair bit of elbow grease to use up before it will be ready.

I spent yesterday cutting the Swarbrick exhausts. Swarbrick say that you should use 2 hacksaws size by side but that was taking ages and the cuts would not allow much in the way of bend. So I used an angle grinder with a thin cutter. This was much better, can't wait to get them welded up.

wow, everything looks killer. I agree with everyone else, the gold on the engine is very nice looking.

earlier you said something about black with yellow stripes?? I like that idea. also like the idea of the dummy lights in the 3 tree.

Footrest plates almost finished. I cannot finish them until I have the Exhausts completed, then I can drill the fixing points on the footrests.








I'm still playing around with the seat , This one was molded using builders insulation carved and sanded, then laying fiberglass over it. I will be trying again using woven mat as chopped mat is pretty crap really.

Quick check to see if the exhausts are bent correctly, left hand set needs another cut to angle up and out.

Seat neads extending down to cover the tubes.

I also managed to sort out the starter motor and it now turns over on the button, now I just need to get the timing right and ensure I have a spark.

Get the exhausts fully welded up with brackets and polish the tank up, then it's time to flash her up and start fiddling with the carb settings. Then it just needs the fairing, seat and brakes sorting out.

Nice work Skunkmiester!!!
Little remark about the seat hump, personally think it should be somewhat bigger to match the rest of that nice bike. But that purely personal.

Carry on.

Rob.
Better sorry for failing then for the lack of trying.

Thanks Voxhonda, I agree about the seat hump, I need to look at redesigning something that has a stronger look.

EBCB, I have some phots but would rather wait till they are welded up and have brackets welded on, the cuts look dreadful at the moment and I would do it differently if I had to do them again. Once welded and painted the peipes will look pretty good...I hope.

Gotcha - I'd like to do soemthing similar to my 550, that's why I asked. Might save me a few bucks and some skin on my knuckles to see what others have done.

The advice given by the pipe fabricators was to use 2 hacksaw blades taped together and cut through the pipes 3 times but not all the way through (leave 2 cm of pipe on the outside of the bend) but that doesn't take away enough materiel to effect a bend and would require 12 cuts. So I made 6 cuts using a single blade and opened out the pipe and then ground down the material in a wedge using an angle grinder. This gives a better mating surface for welding  all around the pipe and adds enough bend into the pipe.
