Custom mount for the top bolt and a door spring to hold the rear. :-)

Would you elaborate on this please and can you post some photos from the side with the tank fitted in place? This sounds far too easy...
Will the spring be adequate? You don't want the tank bouncing about.

It's that easy.  The bolt alone holds things tight the spring is there to counter the bolt tightness slightly. The pads on the tank touch the frame pads. Now I did grind the frame slightly to make the tank sit flat.

The thread already has pics you are asking about.

If he rubber mounts the tank, the spring idea will actually counter vibration. Olde school used a leather strap on tanks. You do not want to hard bolt them down, as vibration with micro-crack the tank.
Springs are also useful for exhaust headers where vibration loosens bolts.

I should also mention I used a rubber washer on the top tank bolt too to help with vibration.

So while I haven't been making build progress I have been doing research.  I really wanted to leave the forks and swingarm alone in the build but I can't help myself. I want the modern updates mostly to replace the wheels.

Based on that I would make the effort to replace the forks wheels and brakes but I wanted to try to avoid replacing the swingarm. So research had to take place.

So I have done that. The tr1 swingarm is actually extremely wide. It's wider than the 07 R1 actually by an inch. There is room front and back as well. So now I'm sold on this direction as a 180+ rear will fit no problem.

Here are some examples.

Ps now I have baked this new direction I'm ready to move on with the exhaust. I put it on hold because if I was going to swap swingarm my exhaust would need to route differently. So I attack that tomorrow.

I don't know how "good" you are with carbon fiber, but that might be the material of choice to get as many pick ups (rear sets, exhaust, swing arm bracing) as you want at a fractin of the weight and with a new looK??

The bottom picture, number 80, is lovely.  However, even wearing leathers that must get a bit uncomfortable?  I see it looks like he has drilled his seat hump to allow some of the heat to escape.  I should think either tape or a pipe guard, and probably both, would be neccesary for street use.

Ya I will see what I can do with the CF. Im sure I will swearing at some point.. oh and the sanding  :'(...  ;)

Got some updates here. I have the modern swap nailed down to either 08 gsxr 600/750 forks and wheels or 2001 Yamaha YZF600R forks and wheels. The YZF is going to be around 500 bucks cheaper. Both include the brakes, etc, Now I do have money for the newer stuff but I don't gratuitously spend it. I think I spent 1300 on my R1 parts for my kz so this swap is already quite a bit cheaper. I am swinging more towards the gxr due to newer the newer stuff and lots of available parts.

2001 Yamaha YZF600R

PROS

- The YZF will be a bit of an easier rear swap sprocket alignment wise due to the 160 rear tire.
- NON USD Forks will take fork gators!!
- Almost half the price.
- Comes with tires (cant tell if they are any good though).

CONS
- Conventional  forks.
- 160 rear tire.
- Older by 7 years.
- Wheels look heavier.


2008 GSXR 600/750

PROS

- I really like the GSXR wheels!
- 180 rear tire.
- Monoblocks and monoblock swaps.
- USD forks.
- Better suspension performance.
- New (fresher!)
- Forks are 738mm!! Good for vintage swap.
- Lots of aftermarket wheel options.

CONS

- I'm not sure for both swaps but for the gsxr I will need to mod the front sprocket to create an offset.
- $500 more expensive, that money could go to FCR carbs!

A couple street fighter pics of each wheels. I picked SF cause you can see the wheels more. YZF first, GSXR second.

I also made some build progress!!

First I got rid of the center stand part of the frame. That's right! More choppidy chop chop! Why? Cause it was in the way of my equal length rear exhaust routing. I had to take off the kick stand cause it was in the way of grind off the center stand part of the frame. The kickstand was in a state of grossness. 100 years of dripping lithium chain grease is my guess so I gave it a clean and a quick polish.

I got back to the rear exhaust and welded the next piece. Then the next set of pieces I have half ready and decided to  tackle the right side first to make sure my left side pipe doesn't get in the way of the complex rear routing.
