Thanks guys. :)

Earlier in the build I was debating with myself regarding what kind of handlebars I should use, well, now I'm there again.

I think the fairing is too far up. If possible, I'd like the fairing to cover the whole lower yoke / tripe clamp but the only way to do that is to either use a straight dragbar or clipons. Well, since I don't have a dragbar lying around I tried some clipons.

Removed the fork extensions and dropped the forks about 45mm. A bit less ground clearance and a bit steeper fork angle, but it's hard to say how much this will affect the handling. Could work really good, could be terrible. Same thing goes for the other solution as well though...

Anyway.

I quite like the feel of the clipons. They aren't spot on but that's because I have them reversed (left on right, right on left), otherwise they wouldn't fit.

The stance of the bike is a bit more agressive and the clipons are about 150-200mm (6-8") lower than if I use the fatbars, so the riding position is a bit more "active" and not as relaxed as before, but it's by no means uncomfortable.

DSC_0008-13.jpg


It's really a matter of preferences and priorities. Gonna do some more testing today and see what I end up with. So far, I kinda like the clipons.

Another possibility:

Laverda bars....

That seating position looks pretty good to me. Not too much weight on your wrists and not too much on your butt. It should be very comfortable I would think.

Another option would be a set of SV650 clipons. They have a 1.5" rise compared to GSXR.

Your bike is looking awesome and an inspiration to all of us!!

When do you plan on starting on the engine??

Hopefully this week. Parts should arrive within the next hour.

Last night I went ahead and sorted out some Laverda bars. I knew the local bike dealer had some lying around down in the basement so I snagged them for $10. Went home and took some measurements then I got to work.

Chopped it in half and added a 28,6mm tube so it fits the handlebar risers properly.

DSC_0003-10.jpg


Tacked it together and took it home to see how it would look.

As a Laverda bar has about two million different angles, it doesn't necessarily represent the final look, but I think it's a significant improvement over the fatbar. Fairing comes down about 100mm (4").

DSC_0004-11.jpg


Looks a lot sleeker I think.

DSC_0011-9.jpg


I also made another find at the goldmine. A GS1000S fairing in pretty good shape. Dirty but no major damage to it, was mine for $20.

DSC_0017-5.jpg


I'll probably put up some more pictures later tonight when I got the Laverda bars figured out. I widened them a bit too much so I gotta take off about an inch on either side. Should look (and feel) much better then.

No engine parts today. Should arrive tomorrow sometime during the day. Will try and have some pictures up tomorrow evening when I get home.

Managed to get the Laverda bars sorted out thought. Took a while to figure out a good configuration of angles but in the end, it felt really good. Fit the grips to the handlebars for a more "authentic".

All that was missing was the vroom vroom noises. :(

Anyway, here are the pictures.

DSC_0013-10.jpg


The height of the fairing is where I want it now too. Going to make some brackets for the fairing and the headlight this weekend I think.

DSC_0018-6.jpg


Riders PoV. Looks good enough to me, just weld it up and get some black on the bars and it should be spot on.

DSC_0021-9.jpg


Didn't take any pictures of the paint though. Might do some paint samples soon though!

While I realize the Laverda bars give it a bit of a "unique" look, I don't think it looks bad. What do you guys think?
 
Spent the evening doing some well-needed cleanup of the workbench. Now I actually got somewhere I can work on the engine. :-\\\

DSC_0012-11.jpg


Much better than what it was an hour earlier, that's for sure.

Also remembered that I haven't posted any pictures of the oil cooler, well, here's one.

DSC_0019-7.jpg


Did some minor adjustments to the handlebars as well. Looks like I'll be cutting off an inch on either side to get it a bit "tighter".

DSC_0016-7.jpg


No engine parts today either. The post office is really trying my patience right now. If they don't arrive tomorrow, I'm gonna be angry since it's easter and everyone is off from work...
 
This thread is amazing.... Just cant stop reading it!!!!

Job well done so far Mindless

The bars look sweeeeeeeeeeeeeeeeeet!!!!!

Happy Easter btw

Wooohooo!

Parts finally arrived!

Pingle dual-outlet fueltap, harder valve springs, new valve seals, manual camchain tensioner and last but not least, some WebCam racing camshafts.

DSC_0009-7.jpg


Camshaft specs. The bike should be a different beast altogether after these are put in.

More updates during the weekend. Gonna lathe some bushings for the rear wheel today (or that's the idea) and try to finish up some other small bits.

Till then...

Those are the bars I was considering. I'm sold now! In other words, I like 'em well enough to buy my own!
 
What do you guys think?

personally.... i'd have used clip-ons and a clean top yoke... imho it would look a lot cleaner and less "busy". the bars just have "too much to them... angles, bolts and area".

just my opinion but as ya asked ;)......

The beauty of the Laverda bars have more to do with function than form....they offer virtually infinite adjustability. I think once they've been PC'd black, they should blend in just fine...the fairing will cover it from most angles anyway.:-k

Exactly. Changing the angle of the bars just a bit gives a whole different feel to the bike.

Here's some pictures of the new adjuster blocks, caliper mount and the rear wheel bushings.

DSC_0006-13.jpg


From what I could gather when I measured, the front and rear wheel are in line with eachother, maybe off by a millimeter or two, but nothing major.

DSC_0022-2.jpg


Caliper mount still needs some work, but overall, it's pretty much finished. Now I need to sort out all the minor things that are left on the bike. Gonna start working on some mounts for the headlight and fairing today, start cutting some cardboard. :D

yes, i completely understand the function/form argument.... it was my opinion as i prefer the bare bones look and felt there was "too much going on" above the yoke.... the rest is so well worked/thought out i'm sure mr mindless will do an admirable job or taking care of the asthetics as well as the function... ;)

I see what you're getting at and I kinda agree with you, but part of why it looks so messy right now is because I haven't painted it yet. Once the frame is painted black and all the other details it's going to look much more uniform. ;)

I hope... :D

Hopefully I'll have the frame off to the powdercoaters by the end of the week so from there the project is on the home straight. :)
 
'bout time I did an update...

DSC_0007-9.jpg


Today I managed to finish up all the small bits that were left. Fit the rear light and made a dirt guard for it, fitted the license plate mount and finished up the lock / fastening mechanism for the seat.

DSC_0009-8.jpg


Made the dirt guard behind the light out of some 1.5mm alu-sheet. Just drilled some holes through it so it fits between the bracket for the rearlight and the rearlight itself. Didn't want to start making separate mounts for it so this saved some work. Looks better too.

Next up was the fastening mechanism for the seat. While I say "mechanism" it's actually just a dzus-fastener.

DSC_0026-5.jpg


This is elegantly tucked in under the seat like this.

DSC_0019-8.jpg


Pull the loop down, twist it around and it pops out. Voil?, the seat is loose. Fits like a glove and very rigid. Also drilled the final holes for the dirt guard under the subframe and fitted some pop-nut threads. No pictures of that though I'm afraid.

That was what I did earlier today. Tonight I tore the bike apart again and started plugging all the threads and holes in the frame. Why you ask? Off to the blasters tomorrow and the powdercoaters on Monday. I'll probably get back with some pictures of the result tomorrow.
 
When are you going to paint this machine already???!!

Gezzzzz!!!! :p

I like the idea of the "dzus" fastener on the seat. Nice to be able to pop the seat off without having to kill the bike. Say if access was only a keyed latch and one key in the ignition.

Frame got blasted today but I'm gonna hold of picking it up until Monday when it's actually going to the powdercoaters. Don't want to expose it to any unnecessary moisture before the powdercoater can put the zinc-primer on it. ;)

Gonna fix the tools I need for the head tomorrow so I can start tearing it apart (and put it together again). Tried fitting the intake cam in the head and there sure is a difference in lift, I can tell you that. :rolleyes:

More pictures during the weekend.
