Just some pics... it's coming together. Hope to be riding this thing in a month.

those forks are WAY to low, that is suicide in the making. the ground clearance must be millimetres!!!
 
Those are early GSXR forks, right? Looks like you're putting later model calipers on? And are you going to use bar clamps with handlebars, or leave the clipons? Will the clipons hit the tank?

So many questions....:D
 
:lol:

The front end is bottomed out in that picture... I don't have the springs fitted :D Fork travel is 4" ground clearance is a little lower than stock but should be no more than an inch.

The scissor jack is there ready to jack it up for spring fitting... which is now done. More pics to follow.

I'm using the clipons but with custom bent bars - more pics to follow. No they don't touch the tank because I made some custom steering stops which are set in the right place! You can see them in the picture. They contact the frame at the same point the originals did. I also made a custom plate to mount the ignition & gauges, the steering lock works too.

Early GSXR 1100 forks. I have the series 1 GSXR brake calipers that are a straight bolt on - 4 pots except there is a clearance issue with the bleed nipple that makes them hard to get on & off so yes I may fit those 6pots but will take some jiggery pokery to get them to fit... Those 6 pots with new pads & master cylinder & Galfer lines cost me about the same as 2 sets of new pads for the 4 pots! Craigslist special.

Been there done that more than once with my GSXR conversion , like when I replumbed my oil cooler :-&

Close tolerance fit huh?

I see - sounds like you've got alot of your jiggery pokery figured out. Those 6 pots sure would look nice on there!

Can't wait to see it all back together.
 
:D My tolerances aren't quite as close as yours Jim but I'm going with a more modern front fender for now...

Tooks some pics earlier with my phone, will try to post. Springs fitted etc.

The Ducati Rear shock is also fitted, frame painted etc.

I also have made a 5.5" rear wheel & 170 tyre fit I believe... Had to use a GS850 rear caliper on the GSXR rotor with custom axle mount & tie bar.
Just waiting for my sprockets & chain but I'm 99.999% sure it's going to be ok from my trial fits. Looking forward to getting it back on two wheels so I can sit on it. I have sort of tried it, might have to make another set of bars with more rise if these ones work out a bit extreme, they seem not too bad though :D

Here we go... Springs fitted, brace fitted (that was why the springs were out in last pic as I wanted to check for binding with the brace fitted).

I have to use an 850 / 1000 caliper with a couple of mm ground off to clear the wheel hub as the stock 750 has a connection for the banjo out of the side which doesn't work as I'm running it an inch or so closer to the swingarm, 850 one is connection out the back which should work fine.
 
Not sure which decals to go with on the side panels or whether to lose the GS altogether (I plan to cut the GS out of GSXR)...

Which do you lot reckon? Top or bottom of the two below??

Great work so far, Dan.
Your workshop looks as crowded as mine, only you are getting things accomplished.
Now....about the brakes on the mountain bike. Are you going with the twin-pot upgrade on the single rotor?
 
Joe,

A lot of this stuff is custom made to my design, those clamps are one such item. Luckily I have access to a full prototyping dept with work so I can get a lot of stuff done in 1's & 2's at relatively low cost. Made in China - eekk :lol:

I can give you the drawing if you want to have some the same made up locally. They are for 41mm fork legs.

Steve - I did run twin piston brakes on a mountain bike in the alps once, they overheated, the single piston with the biggest rotor you can find seems to work best for downhill ;) :D

Dan :)

I like the bottom of the two decals. What would you think about using the X from the GSXR logo too? Afterall...that bike is somewhere between a GS and a GSXR....:cool:
 
Cool project. Can't wait to see how it turns out. And I like the bottom decals better. Good luck.
