My Big Brother Project... 1982 XJ1100

So I finally started in on the 1100. Been a while since I finished the 750 and needed a quick project since I was interested in fabrication again.

Here she is when I picked her up. Non Op with under 9K on the odometer. I have no idea when it last ran....


Started stripping her down and did he rear wheel to front wheel conversion....









Unbolted the back end off to cut the rear frame off...


Rolled some tubing and it started to take shape...





Made myself a seat pan....

 

Raised the forks up in the trees 1.25 inches. Put on some clipons. I have the stock round headlight that I will likely remount. The shocks are sportster and I had to turn some new reducers to make them fit. I ordered some pods to clean up the engine compartment and need to make a battery box and side covers. I Need to rebuild the carbs and make a new more open exhaust. Can anyone confirm that the xs1100 uses the same carbs and what I should rejet the carbs with? Also has anyone made a simplified wiring diagram for the 1100? I'd like to strip it all out and use only what will make it run appropriate. Thanks. HOpefully I can get all the fabrication done with week. Also does anyone know of a simple petcock that will go on these tanks rather than having to find OEM ones? Thanks again.

 

Pic #2 looks like the forks are pinching the front wheel, you may want to check the spacing between the wheel and forks.
Save your airbox to carb boots to velocity stack your pods, it helps smooth out the air turbulence to the carbs that causes tuning headaches.

 

What tires are those?

 

that thing looks mean!

 

mean for sure.

 

500/16 tires. Bikes rolls around just fine. Had to make spacers and bushing to center the wheel up in the forks and space it right on the caliper but not a big deal.

 

Motorcycle tires???

 

If you have the means you could throw the fork legs on a lathe and shave down the fender mounts. You can find tutorials on certain chopper homebuilding websites. Bike looks really cool tho! Digging the custom tail piece!

 

There's a trend to using vintage car tyres, it's all about form rather than function

I like the rear frame treatment, looks like a nice job

 

That's not a car tire, It's a retro cycle tire that looks like a (Coker) car tire.

 

It's a motorcycle tire and its made to be look vintage. Shinko, dunlop, coker, etc... makes them. I may still use the fender mounts to make a small fender so I didn't want to eliminate them as of yet. We'll see.

 

Okay, what's my prize? LOL

 

Bike looked nice stock to me some polishing here and there would have been perfect to me . Your gonna get a real work out with clipons at slow speeds for sure. Definitely changed the appearance. Not my cup of tea but still like looking at the transformation of it. Wish i could find one with that low of miles that was in as good as shape as that was.

 

Even if you don't mount a fender, consider using the mounts for a fork brace. The original fender concealed a rather stiff stamped fork brace welded inside that you lost when you took the fender off. With the rear-front conversion I'm thinking it will be even more necessary than it was to begin with, especially with a bike as heavy as the 1100.

You're also going to want to rebuild the remaining front brake with stainless lines since you've now given away half of your stopping power up front.

 

Can never go wrong with stainless anyhow.

 

Really digging the seat pan.
I'm going to have to make a bob just for kicks and giggles one day
