Is that just a cover? Where did you get that from?

[busa ash]

i must just say "love this build " very original and i like your design ethic of trying too keep as much katanaesque as possible carry on  

really like the battery solution 

[MrS819]

Like the carbon cover and the battery box.

yes - it's a hand laid carbon cover available from here..........

today I have been mostly fitting the Kettle air box - the tw*t put up a hell of a fight - had to remove the original Katana air box mounting bracket on the frame, the Kettle air box side cover mounting lugs and the inlet trunking on the rear of the air box to get it somewhere near. Then I had to beat some subtle dents into the air box upper rear to allow it it to clear the top frame tubes. Funny how an air box for a 3 cylinder 2-stroke is as wide as that for a 4 cylinder 4-stroke, but it's in at last.............

 
although the air box mountings are far from central in the Katana frame..........

tine for some more welding..........

[garry55]

some more progress today......................

new air box mounting bracket fabricated and attached

new air box mounting point installed

air box butchered to allow clearance for frame rails

and some frame bracing

[Rncv]

great work so far, looking forward to the end result

Those gt750 engines are so sweet and mix with katana... perfection

[SiBag]

Nice Work,

I'm going to be watching with interest

[Swiss Toni]

Fascinating!

[KATANAMANGLER]

When working on my own katana I often put the kettle on but I never would have thought to put the kettle in! Inspired.

[Dorkburger]

Damn, this a cool build. The battery box (among other things) is genius. 

[Fazz711]

Any more updates. Wanting to see how this is progressing. 

[garry55]

to preserve as many iconic Katana styling features as possible, whilst significantly updating the bike, I have had a replacement front mudguard fabricated. Shown alongside a 17" original from a GSX250S, it is wider to allow it to fit over a modern, wider 17" tyre...............

i've never seen a two smoker sharing an expansion chamber

[garry55]

It's a Strader system, made in the USA, and modified in the UK so that the tail pipe follows the line of the seat rail - hence the extensions to the header pipes.  Also added some spring hanger attachments on the collector box and 3 pipes.

Piper used to produce a similar system here in the UK.

[Guest Manxzookie]

Not good for performance though 

[garry55]

Not good for top-end performance, true - but they do enrich the low and mid-range performance, which is what I want from my road bike. And they sound like nothing else.................
