Progress!!! 1978 GS1000E Restoration/Performance Rebuild

For all that are curious:

Rapidray built my clutch basket - essentially, it is an 1100 basket machined down to the height of a 1000 basket. Now, keep in mind that the 1100 steel plates are thicker, but smaller in diameter, whereas the 1000 steel plates are slightly thinner but larger in diameter. **The 1000 steel plates are too large in diameter to fit in the 1100 basket** To run the original number of steel plates (7, I think), you will have to purchase 1100 steelies and have them deck sanded to the thickness of the 1000 steelie, OR, you can do what I did, which is take a 1000 steelie and use a lathe to turn down the diameter to that of the 1100 steelie. I am using Fast by Gast 1100 fiber plates and x3 stock springs and x3 EBC springs for the pressure plate. The clutch pull is firm, but if I used x6 EBC springs it would require a gorilla's hand to pull. The clutch basket nut is from APE. As for the performance of the Gast fibers, some claim that they are too grabby - I can't comment on that right now, as my bike is a few steps away from being on the road for the first time! Hope this helps!
 
UPDATE, 4-10

So, after an unexpected delay getting some parts pack from my powdercoater, I decided to get some long overdue work done yesterday.

THE BAD (insert line of expletives here). How did this slip my mind? How did I not check for appropriate petcock clearance? Apparently, I never fitted the tank to the bike with the carbs on... I'm very frustrated with myself because this is an amateurish mistake. As you can see in the photos, one of the petcock hose barbs bits the #1 carb. As for a workaround, I'm going to give Pingel a call on Monday to ask them the physical dimensions of their Guzzler series of petcocks - the different orientation of the barbs may give me enough clearance.


Potential workaround, the dual-outlet Guzzler




THE GOOD:
Headlight brackets installed


Sufficient tank clearance at full lock - yay!

Looking nearly done!

Every time I see your bike I drool... :tongue-new:

You may have already covered this, but do you plan on getting case emblems?

Thanks Sam! Long story short, I restored my old case emblems, however, I found a guy in England that make heavy-duty vinyl reproductions of the original 1978 Suzuki emblems - I will put them on next week. They look great, and if one gets messed up, I can replace it easily.
 
I have to ask- will this bike ever see the road, or is it a museum piece? I love the cleanliness, but can't imagine the misery of dealing with road wear on a bike this clean.

I appreciate the question - the bike will see some use on the weekends, as well as going to the occasional vintage Japanese bike show :-) However, it's not going to be a daily rider of any sort, as I sold my 2007 Yamaha FZ6 (which was my daily rider) and finally got around to working on my 1998 Ducati Monster Dark - the Duc will soon be the bike for bombing around town.

I admittedly have come to the realization that I may enjoy working on bikes a bit more than riding them - you might a call it a passion for the craft, and a genuine desire to build beautiful things.
 
Petcock Update!

Called Pingel this morning and a guy in the tech department was nice enough to grab a Guzzler GV111G and measure it for me - the body is only 1" wide and 1.4" tall. It will work! Ordered one today and it should be here by the end of the week.
 
Where did you get your headlight bracket? Or was that custom made?

Dang, your bike is gorgeous! What are you going to do with yourself when it's done? Ride the crap out of it hopefully! Congrats. :)

I had the silver piece custom machined, whereas the other pieces were purchased from Dime City Cycles. I found it necessary to spread the headlight brackets apart in order to make sufficient clearance between the brackets and the tank at full steering lock. Also, this created a solution to another problem - I was now able to use the brackets to hold down the lower decorative triple cover. I simply created some spacers out of black ABS pipe and sandwiched the spacers between the brackets and the triple cover.

Personally speaking wrenching = means to an end, though I enjoy the process of more then I once did.
 
Two coats primer:










I have a couple of questions going back a ways from where you are now....

How did you get down in the fins on top of the head. I've soda blasted and scrubbed, but I still have black spots from the vibration dampers, etc.
Also, how did you cut those circles for masking the bolt holes and spark plug holes, etc. How did you remove the tiny spots of masking tape without messing up the paint around it?

With respect to the stains on the head, as long as you have done a thorough job of soda blasting, degreasing, and washing the head, don't worry about it. The aluminum is slightly porus, making some stains very difficult to remove. If you are genuinely worried, wash the head, and then put it in an oven around 200F for an hour - this will help to bring out any oil that is just below the surface. After that, let it cool, soda blast it again, and then put it in the dishwasher on the hi-temp cycle. Squeaky clean head :-) Now, this is assuming your head is totally disassembled - if not, then go back to what I originally said, which is don't worry about it - soda blast, wash, and then wipe with acetone.

The masking tape circles are pre-punched masking discs from McMaster Carr in various sizes: https://www.mcmaster.com/#masking-tape-discs/=17air1i

They can withstand temperatures up to 325F, so, once all of my parts were primed and painted, I put the parts in the oven to cure with the masking discs still applied - once the parts had cured and cooled down, I then removed all of the discs with a tweezers and x-acto knife. No damage to the paint!
