Time for a change - Perhaps a bit of 'Bobbery'
« on: November 08, 2012, 07:57:29 AM »
Having the old Cafe Racer now for almost 11 years, I am feeling the need for a little change.  The 'Long Live the Kings' thread and the fact that a lot of my riding these days is on speed limited roads, I am thinking of changing my Cafe Racer to a Bobber.

Dropping the clip-ons and rear sets for a set of standard pegs and wider bars.  Possibly with a new single seat should be all thats necessary.  Not a big job, but I will probably use it more in this guise that in its current form, its becoming a bit of a bind in slow town traffic and I am getting older.  Perhaps some exhaust tape and a few other minor changes

Not going to do a full strip yet though as money will be limited.  

Be nice to potter around the country lanes and byways in the summer out of the ways of the race-rep brigade.

Any thoughts?

It's your bike, but please no!  I love your bike the way it is.  I potter around on my bicycle.

Do not worry Ed.

Nothing I will do will be 'undoable' it really amount to just a change of riding position:

1.  Re-instate a set of handlebars instead of the clip-ons - I have a USA set of high bars (RT), but might go for a pair of 'trail bike' bars.

2.  Re-instate a standard set of foot pegs and levers in place of the rear sets.

3. Re-instate the hoop on the rear sub frame, but at a tilted up angle to pick the rear fender so that I have a more rigid point to hang my number plate and rear light.

4.  Replace the seat with a single seat with no hump, the base of which will be home made.

5.  I will have to fiddle with the idiot light/ingnition mount as I will be using the top yoke agin to mount the handle bars.  But I will make a new one.

There will be no matt black and no removal of fenders etc, as I live in England and we have weather.  If it does not work out, I will just put it back to a Cafe Racer

Cheers

I think it sounds great Steve.  Ed is just worried because it shows so well in photos in it's cafe guise. :)

You might want to consider a Vapor instrument cluster, if it's not too "modern" for your tastes.

Certainly cheap enough, and will give you all kinds of information.

Yes my brother has one on his R100GS.

I have this setup.  I will keep it as it is, just make a new plate to hold the Idiot lights and ignition as I will be using the handlebar clamps again.

If I could make a Vapor/Vector install look that good I would put one on my Triumph.  I never seem to be able to keep a speedometer and drive both working at the same time on that bike.

Okay,

Being a man of action, I have started the transformation.

I had a set of LT bars in the spares pile, so I though I would initially use these on the front end to get all my brake line, cables and wiring sorted.  I have also removed the rear-sets and gone back to standard pegs and controls.

It does not look if I have actually done much, but most of the work is hidden under the tank, or it has been a direct replacement scenario.  So it has taken me two weekends to:

1.  Extend all wiring from the controls - 8 inch entensions, soldered and heat shrinked on every wire.  A bit of fault diagnosis because I missed out an earth ;)
2.  Replace front brake pipe with longer BF Goodrich hose and bleed the system.
3.  Reposition the ignition and idiot light cluster.
4.  Move the stantions and reposition the head light and all the tomfoolery with front end semi strip down.
5.  Route new throttle cables and clutch cable (done several times to find optimum route), retune/balance carbs for new cables using my £5.00 carb balancer.
6. Remove rear-sets and search the garage high and low for the old pegs and levers.  Had to order a new gear linkage as my bent piece of wire (kinematic lingage) had been lost in the last 10 years!  Went for an adjustable type off of the larger airheads - but I had to shorten it to get the gear lever in correct position.  Had to make up a new bush for my brake pedal as original was missing.
7.  Test all lights and controls for correct operation - Check ride to adjust position of all and sundry.

So what does go like:

Well, the steering is lazier, as I cannot have the stantions poking up through the top yoke a full half inch to account for the larger 19 inch front wheel as the handle bars are in the way.  I am considering making up some short risers - only 5 or 10 mm, so I can level the bike up again and quicken the steering.  My weight is also further back, which also might have some bearing on the situation.  I do not want to preload the shocks as I will just get a bone jarring ride.

What's next:

I have to look at the rear end - I need to re-instate the hoop on the sub-frame before I can make a new saddle - And I am going to introduce a bit of a 'kick up' on the hoop to pick up a new alloy rear mudguard.  I am currently considering either a single seat or a dual seat.  And I will have to change the rear light to something a little more stylish.

The current handle-bars are temporary, they are too high - I will be going for something between the LT and 'Euro' flat bar - only wider - I'll know it when I see it.

I will be saving all my Cafe-Racer bits, just in case a change of circumstances makes it more viable again.

There you go then, rode her to work this morning in -2 deg Celcius.  Did not ecxeed 30 miles an hour through town and all is well - especially my wrists!

Good man. That should have been me this morning and was last year. I've had to compromise because I'm giving my wife a lift into work at the moment and while I might just get away with + 2 there's no chance with -2.  

I've got a feeling it's going to be a slightly longer lay up than 6 weeks this winter.

I am currently working on the rear end at the moment.  A mate of mine is helping.  We have re-instated the rear hoop on the subframe, although it has been shortened by 2 or 3 inches.  The awkward part of it was that the subframe has an insert inside the outer tube that is obviously there for strengthening, but is not welded - I was trying to insert a strengthening rod, and this insert was just moving around inside the tube.  Got over it eventually though.

We decided we would try and do a hugger type rear mudguard using an alloy mudguard and some stays onto the swing arm rather than onto the subframe.  Mounting the stays on the swing arm is the first point of order.

Will post a picture soonest as we make progress.  Have to make a saddle as well.

Steve

I mounted my rear mudguard stays on the inside of the twinshocks.
you have to manipulate one side but it's easy done & that way the mudguard moves with the wheel

That is what I am going to do.

In the picture you can seen a 'practice' bracket that will go behind the shocks, on both sides, with holes drilled in each 'ear' to pick up a couple of stays, one either side of the shock.

I need to find somethin to use for the stays.

Also the saddle will now sit directly on the top of the subframe.  And only be an inch or so thick.  I will post the look that I am after.

You can see in the picture how the 10 year old red powder coating has faded - orange on the outside and reddish on the inside.  It is all going to have to be taken apart agian as repainted

Mr E, what did you do with forward end of the mudguard, where it comes down to meet the swing arm?

Saddle wise, this is the sort of look.

The bike itself is not far off, but being in the UK I cannot do without Mudguards!
