Yoshimura GSX1135R (EFE) Project

The sharp lines, combined with the modern underpinnings, create a very well put-together look. The inherent simplicity of the GS engine, and the overall cleanliness of the build give it a very purposeful, industrial look. Nothing wasted. The stance makes it look like it's leaping forward, just on the paddock stands.

It's sorta like a brick wrapped in crushed velvet. It's classy looking, but sharp-edged and hard as nails at the same time.

Thanks! I inteded to use the less modern running gear from my dads bike (which we rebuilt last year) but as I've mentioned, this turned to that and here we are. I like the look of oldschool wheels on an oldschool bike but the modern Aprilia wheels are a step up, not only looks but the fact that they are a few kilos lighter. The less unsprung weight you have = the better.

The overall look is the result of "keeping it simple". I don't want bits on the bike that serves no purpose. Just trying to follow the original lines and do some tweaks to enhance the look basically.

The plot thickens......this is getting really good

This is an awesome build. You are the man!

Thanks guys!

The more i see that exhaust can, the closer my fingers get to the buy it now button.
Everything is looking awesome.

Do it. The craftsmanship on it is great and the sound is probably amazing.

I'll try the RS3 i have first, but those cans are so much thinner. They look great and more to the era than what i have(except the carbon i guess)

[Mindless]

Well, got some rubber fitted to the wheels now. She looks great when she sits on the ground.

Bit of a cocktease first.



Could look at that rear end all night.

Now for the whole picture.




Dunno about you guys but I very much like the way it looks. Ride height is just about right, bike feels rigid as hell and probably most of all - it's so much lighter. Sure, I'm missing the electrics, a few gallons of fuel, a bit of oil and two camshafts in the engine, but it's still significantly lighter than it was when I first got it. Probably saved 20-25 pounds on the wheels alone.

It's going to be a completely different ride once it's done, that's for sure.

Here in the states that look would be know as just SICK! So awesome great job man!

[Zweihammer]

Damn, Mindless, that is teh seksy. I am impressed at your focus and attention to detail. I can't wait so see your final result.
Cheers, Erick

Your bike is lookin' tough! Those wheels look fantastic!

[Mindless]

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.



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....

[Ogri]

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.

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.



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").



Looks a lot sleeker I think.



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.



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.

[Mindless]

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.



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.



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



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?

[Mindless]

Spent the evening doing some well-needed cleanup of the workbench. Now I actually got somewhere I can work on the engine.



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.



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".



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...

[taswegian]

This thread is amazing.... Just cant stop reading it!!!!

Job well done so far Mindless

The bars look sweeeeeeeeeeeeeeeeeet!!!!!

Happy Easter btw

[Mindless]

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.



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...

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?

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