Just looking at your earlier posts about exhausts -Predator motorsports in Welwyn make stainless exhausts for bikes. Might be worth a call there. They've been around for ages but I haven't personally used them.

SumpMagnet:
thanks for the tip Andy... Predator are on my radar, but the more I think about it, the more I have to conclude I will either have to compromise....or get a more bespoke solution. That will depend on how the finances look when the time comes. I've been out of work for a few months, and am watching the pennies closely. I have a chunk of money from the sale of my old Hornet in the bank for the bike fund....so we will see. The more I can save elsewhere, the more will be there for shinies :)

But I do have a plan B ..... or is it C .... or D ... if I can just get the damn stock headers apart!

SumpMagnet:
Following the shjocking revelations in Practical Sportsbike that my great idea was absolutely not original, already done...and therefore old-hat, I was not discouraged.

My first attempt was a tragedy of epic proportions, but was enough to convince me the idea was a good one, but my approach was wrong. I tried to build a mould out of the rear section of the tank, and then remove material to narrow it down ..... as it would otherwise be too large. Sadly.....what also became apparant, was that every other curve, slope and angle also appeared wrong. By the time I had chopped it a couple of times, taped the bits back together and offered it up a load of times....I could see the thing was never going to be blending in like I wanted.

So I binned it.

Not to be beaten, however, I had another go. I had bought some expanding foam filler for a job on the house, and had about half a can left...so I made a little polystyrene base, greased up the back of the fuel tank, covered anything likely to get gunk on it ....and sprayed up a big pile of foam to fill the gap between the back of the tank and the seat. Took a copuple of goes to get it all ....as put too much on and its prone to sag...but it was done!

Then I could carve it back once fully set and blend it with the tanks curves, forming the shape I wanted. It sands really easily, and can be chopped to a rough shape with a saw. Card templated helped me to get it symetrical.

I made it undersize.....as my plan was to lay the fibreglass straight on it, tidying up the surface with a thin skim of filler.

The final cutting of hte edges and the surface finish has yet to be done, but I like whats done so far.





The fit at the back isn't perfect, and needs some fettling...which is making it ride up slightly and angle to one side when let go of. Push it into place, and it looks spot on though.
Once I finish trimming the back and getting it square, it will fit. No idea why the first pic has come out blurry....but you get the idea. Next job is to sand it flat, and apply filler to the imperfections.

Now that's coming on a treat, good skills!
I read about your rear-sets and thought straight away, before I'd got to the end of the sentence......."CBR600 of some incarnation will fit". They read that's what you did! Im not that soft then? Winning! ;D

Re the master cylinder, I shared this with Allen on his disc conversion but have you had a look at the HRC M/C option?

Much cheapness, bit racey :o, still Honda but most of all............its only £14 and HRC!!!!    Whoop whoop!


Ebay item...162805847400
I had one on my Ducati 748/853 and was so simple, worked a treat and very unobtrusive but looked great. (if you're an HRC lover as I am) 8)
