Dual front discs?

[skillzman1]

Just looking over my new parts...and the front forks have bolt/bracket provisions on both front forks.
the wheel has a plastic cover over the left side of the hub.
If I remove that plastic cover am I likely to find threaded holes that would accept another front disc?
If so...how does the cover come off?

and where do I find a left side bracket and caliper?

any experience with this?

yep done that.

cover just flicks off with a flat blade screwdriver.

you'll need a new M/C which can push more fluid (i usd an xs1100, as it looked like the original) SR500 left caliper and mount (or use the xs750, 850 1100), new brake pipes (best from the M/C, rather than a splitter) and that's it.

so if I ebay search for the larger xs bikes I should be able to find what I need....excellent...thanks Drewpy!!

 

[drewpy]

when I have some time I'll do a "how to" as I took pikkies when I did mine. also have the brake hose lengths you need.

So which models came with the fork legs with extra mount ?

My bike has the extra caliper mounts on the left fork leg and its a '79 XS400D.

anyone know if any of the cast 18" front wheels have the extra holes for second rotor?
I see some 19's with them, but can't find an 18

 

[drewpy]

I thought that was the point of the whole thread? xs400 only has 18" front wheels

My front alloy does not have extra holes nor the cover. Its an '82 German version.
But im fairly sure it has the extrusions, so i guess they just stopped machining and drilling that part of the wheel.

 

[Hornix]

I had a Canadian '77 and a Dutch '81 XS400 and they both had that plastic ring and 6 new holes for a second disc in 'm. Only the '77 had bracket for a second caliper.

 

[frwinks]

that's my point.. my '82 doesn't have them either, thought they were only on 19's. Sounds like only certain models/years of the 400's got 'em .

 

[HoughMade]

My '79 XS400F with 18" alloys has the holes on the left, but there are plugs in the holes. Anyone know if they are threaded or just plugged holes?

[edit] Here is a pic:

 

[drewpy]

plugged that was my answer but i have to write more coz it wont post otherwise

 

[OliverB]

Extrusions present but not drilled and plugged on my "80 front alloy wheel.

 

[drewpy]

the bikes in the uk are all drilled , as I have never seen any other!

someone will prove me wrong now

Old thread.. But I have newer forks that I'm planning on running a dual disc in front... I don't see the cap you're referring to that I can mount rotor number two on...

Help?

Thank you!!

The cap is that big star like plastic piece covering the center of the wheel right behind the speedo. If you use a screw driver it should pop off and you should see the mounting holes.

Still confused..

What I'm saying is I don't see how this pops off.... I mean.. I HOPE it does!

Thank you all again for the help!
