I like what you did with your '86! Makes me wanna get mine back on the road! Mine will be a bit higher in the rear as well and I'm sure I measured how much at one time. The shock is a Penske w/remote res and I've tried to mimic the FZ1 geometry with the top mount. It's pretty much vertical and I know I'll need a stiffer spring than it has. Do you know what spring rate you ended up with? The front of course is just FZ1 that's plug and play in the FJ with FZ bars and all that.
I lot of what I've done is for aesthetics (to my eye anyway). Ton of work on the R6 tail conversion. The top cover for the tail I made from some kind of lightweight composite. Paint is by yours truly as well; I put FJ1200 on the fairing with a ghosted in pearl under the clear as well as some striping on the rear top cover. Pops in the sunlight. I machined the footpegs, and mounting plates from billet. Planning on 3d printing a mount for the remote reservoir to hang on the left side. Modified a chainguard to a minimal look and added some lightness to the front sprocket cover. Need to take a few more pics I guess.

Put her on the Scale at work yesterday.
With no luggage, and with a full tank of Fuel, she sits right at 600-lbs "ready to ride"......
"This is Heavy-Bike!"

On again legends.

Gav's motor woke up at the last one.
Troyskie told some tall stories.
Bikes were sorted.
Snags were BBQ'd.
Beers were drunk (and some rum I believe ).

Lets do it again!!!

This has been answered in your other post.

Update:
It's called a clutch push rod oil seal, they have them on eBay for around $10 OEM. Thanks everyone for the help, will update when it arrives and I get it on the road. You guys are the best. Cheers!

Pull the rod out, then the seal can be pry'ed out with a flat blade screwdriver.
 It comes out easy.

Ok, that's not too bad. It's a good idea to run some gas (with Seafoam cleaner)  thru those carbs and get some miles on that engine. Perhaps that's all that's needed?

I have a hunch that your bike will run better the more miles you ride.

Also...If you use a little oil, so be it, don't worry. Our air cooled engines have loose piston ring tolerances to account for the latent heat build up we get.

Cheers

Thanks for the info! Do you know how I replace that seal that the shaft rides on?

It's not that bad the bike actually runs really well it's just a slight bog off idle and I have screws 3 1/8 turns which I know is a lot, enough I know it's not right but I've comfortably rode around without issue and even on backroads I'm always in the middle of the rpm range like 2500-4500 so as long as it's not hurting the bike I'll do another cleaning on my own and try to rack some miles up and see how it is
