It was a relief when it ran thats for sure!
Still a long way off running right but thats a job for someone who knows more than me and has the experience of tuning these things.
Got a Buell front end and rear wheel going in. Thats really all thats holding me up now.
Engine wise, everyting has been spec'd for 300bhp or more. Not going to get that much power but the headroom is there and it should hopefully be reliable.
I'll be happy with over 200bhp but 250+ would be nice.
Main thing is it has to be ridable and useable power.

I doubt any manufacturer uses standard brakes on their race bikes, just they don't have the option to add an extra disc.
Obviously it depends who you talk to and what you read but the worst I've heard about them is that they're no better than a good duel disc setup.
The benefit however comes from the bigger surface area of the disc keeping it cooler and the ability to be able to use a much lighter wheel , these give less rotating and unsprung mass so makes it easier to stop.
I certainly don't think its going to be any worse than a conventional twin disc setup.
So I've been having wheel to rad clearance issues again, it was close with the 750 front end in and the bike sat a little high. The Buell forks are 30mm shorter though so it would've meant having the bike sit high, the front wheel coming close to the rad under heavy braking and a big step on the top yoke to meet the forks.
With all that I decided to sort it properly and cut the rad down. The bike sits at the right height and I'll have enough clearance between the rad and front wheel.
That's actually the second attempt at welding the bottom up, the cross sections are .5mm thick so a slight jump on the arc or a little slip with the tig torch puts a pin hole in it!
Could be neater welds I think but I'm not exactly a pro welder...
Yes its a rough rad but if it works I'll look out for a decent one to alter.
Got the boost gauge mounted too, cut the mount off the old bracket with the gsxr clocks, tidied it up and welded a nut on the light frame.
Nice and easy.

So the rad is finished, leak tested and new mounts made on the bottom. Will probably make a better one once I know it'll work ok. No pics yet.
Also mounted the speed sensor, that was actually nice and easy.
Aquired a lathe off my dad the other week as well, nice freebie as he was upgradig.
Got the throttle body on there to open up the back so its round and matches the turbo intake.

Things are still moving slowly, I have a date with WSR to fit the lock up clutch and he'll also take it to the dyno for setting up the efi while I'm on holiday! 
For now though, clip ons arrived but didn't fit, had to cut and weld some bars up on an angle to get them to clear the fairings, need to sort something better out really but it'll get it rolling. Also need a matching clutch master cylinder.
Clutch plates have had a nice oil bath and are fitted.
Bit of a rush to get the cush hub and top yoke made now, cush hub should be test fitted early next week, part one is made with part two on the mill.
Will then be anodised before fitting.
Bit hard to describe how the cush will work but it'll be clearer once both bits are made.
Top yoke is still in the design stages but I'm hoping it'll be ready in the next week or so. Fingers crossed.

Things are moving!
Tiff has been a busy boy designing and milling the cush hub.
Work of art really.
The back plate which bolts to the wheel is shown above.
Fitted with 12 bits of polyurethane rod
The top cover sits over the back plate. This has a bearing to carry the load and carries the sprocket which actually sits behind the back plate. Make sense?
All held in place with a top hat spacer which makes it easy to just slot the wheel in the swinger and it also carries the wheel bearing to sleeve that down the the K4 spindle diameter.
Trial fit without the sprocket.
Assembled without the poly rods for now to make sure everything moves as it should. The chain is a little tight but I have a few spare links to go in.
This will be heading back to Tiff now for a final touch up then anodising.
Top yoke design is well under way and milling should start soon.
This will be at WSR in 2 weeks time. They'll finish the lock up clutch, take it to their tuning guy who will get it on the dyno and set up the fuel injection.
Hopefully WSR will mot it as well so when I get back off holiday it'll be good to go!

Looking very trick, can't wait to see it when it's completed.
Not sure Dan will want to know

Haha, total cost....
No idea and I don't want to know. I'm coming up to 5 years building now and while I've rebuilt and repaired other bikes in the mean time, plus holidays etc, it's taken all my spare cash since day one.
There's not much that I haven't changed though so I've bought a lot that's been sold on or stashed in a box somewhere.
Well worth it though!

Phenomenal project! Will be cool to see the dyno charts when it's been tuned.
Been a busy last few days but its rolling and I dropped it off last night for the lock up clutch and dyno time.
The top yoke wasn't ready in time so I've wedged an RF6 front end in for now. I'm away for a few weeks so by the time I get back the yokes will be made and anodised ready to drop the front end in.
Hopefully everything works and it'll be running nicely and I'll have some initial bhp and afr figures.
Last pic before the cush hub was fitted.
Watch this space in 3-4 weeks time!
