The petcocks are famous for broken membranes.
I switched mine out for 'normal ones' from mikexs.
If the membrane breaks,fuel will flow down into the gear box....

Open up the gear box oil plug and have a smell...if it smells like gas you know...

So, after some research and seeing people comments I think a Brat style is what I'm after. The cafe racer look is sick! Only if done proper and to the fullest. The xs1100 might not be the best base. After day 1 of Project: JohnnyBrat.  Check the progress! (The fork won't be lowered that much!)



Future Mods:
Brat seat
Clip on fork bars
Round headlight
Relocated gauges  (stock to keep that 70s feel)
Kill switch relocation
Chopped and rounded seat rail
New front fender (shorty)
Pull the muffler and find a nicer sounding short pipe.


Any other suggestions for this project? Let me know!

Stock clocks?  That is one big ugly console.  Going where you're going, they'll have to go.

Is the bike sorted?  Does it run?  I'd stop there and do all of the service items.  I bet the swingarm bearings have never been greased.  Steering bearings and fork oil need service too.  Valves adjusted?  Cam chain?  CV carbs like the airbox.  Looks like you might have new brake lines.  Good!  If fenderless, you'll have to have a fork brace.

You may consider a stockish redo, with bulky offensive parts replaced.  I agree, square headlight is ugly, as is the aforementioned speedo-tack.  Turn signals are also giant.  Minimize that stuff with maybe a Maier fairing and it will look sporty.  The stock seat on those looks good already.  Euro controls to get your feet farther back are a nice option too.

BTW, that was a pretty cool period paint job it was wearing.  Best wishes!

Looking at your photos, your forks are not 1978 XS1100E.  They're from a Special.  I have to wonder if the triple clamps are standard or Special, because they should match for proper handling.  Your handlebars are also Special.  Is the rear wheel 16 or 17"?  17" would be correct for a 1978 standard.

Hey Jetmechmarty ,

The entire front end is off a special, as far as i know. With regards to mechanics it runs perfect! I will add a video to youtube showing a cold start after like months and months of sitting. I will have to go through it for sure but, it runs great i was actually SOOOO surprised!

I just picked up clip on bars and a headlight bracket. I do however have my old round headlight off of  a Buell X1 project i did a while back which im going to install. Im still not 100% certain what im going to do with that big 'ol honking gauge cluster though LOL. (suggestions would help) I do like the look of the one square gauge. I want it looking a bit true to era and time period. 

As far as future mods go hee is a list:
-Clip on bars
-Round head light
-LED flashers (new no load flasher unit)
-Brat seat with Seat hoop
-LED strip tail light with turn signals integrated
-Re-located push start using a RED light elevator button
-Modded gauge cluster
-Bar end mirrors

Nice looking bike.  I would use superbike bars instead of clip ons if I were you.  With such a heavy bike you could use the extra leverage.

The one thing I remember from my XS1100: Make sure the vacuum ignition advance works. If the line has got a small leak, it can drive you nuts.  ::) Symptoms range from no idle when hot, to no idle when cold, pinging,...

I liked mine, but only with a sidecar attached.

Click >

Let me know if you hear anything wrong during idle... I think its running fine (After the choke was pulled out!!!  :-[ haha)

I will be continously posting videos of the build. And, maybe some how to videos...

Let me know what you all think!

Cheers.

HA Nice! - Fellow youtuber here (AimlessMoto)

It sounds really, really good... no clicks, bangs or pops, and it seems it's running on all 4. The "blue/purple" on the pipes is a little concerning that it's running hot, possibly a little lean.

I would strip the thing to nothing, keep the paint on the tank just the way it is with a gold "Yamaha" sticker, and go to town on a café build. Rear seat hump, full fairing, the works. R1 front forks.. the whole deal.

Could make an amazing bike!

Hey Hey AimlessMoto,

Thanks!

Yea i will check it all out before i start riding it. I think the build is going to be a Brat style though it just seem that the XS11 is too large to make a cafe unless done 100% correct!

Also, im looking for information about the NoLoad flasher units. Anyone know of a link on the site that has a good how to thread??

Cheers!
