Which Spares To Take, R850r

I have two R850R, one is a 95, the other a 2000.both work fine....my plan is to prepare one using the best parts, I figure to use the 95 as it will be older ie cheaper for the carnet etc..the second bike I will strip and keep as spares to be sent whenever I need them.....my question is which parts would you carry that are small and would get you out of trouble...
eg..cdi, fuel pump, hall effect switch...
some of you will no doubt say leave the bike in one piece and only take bits off when you need them but I would have a prob as would have to get someone to go round and do this but my way it would be in a box packed and ready to go. Those that say take the newer bike..on these its easy to swap the headstock, ie frame number..the newer bike becomes the old in a couple of hours......

pair spark plugs, throttle cables, fuses, bit of wire, bit of insulation tape, box of nuts/bolts/washers, tyre plugging kit, inner tube, misc. bulbs.

Some parts are 'consumables' .. depending on the length of your trip. And some of it depends on where you are going ..

I'll assume it is a long trip .. and you'll be waring out
alternator belt/s ..
spark plugs
air, oil and fuel filters

These are not things you'd want to carry .. but schedual for replacement at convient places ...

the things you want to carry with you are items that are known to fail frequently and without warning ... and small ..

Before the hall effect switches .. a fuel filter or two (not small, alows for bad fuel). An alternator belt (unless the one on the bike is newish). I'd not take a CDI box nor coil - too infrequent a failure. Nor bearings.

Up to you. If you do carry spares - the worst bit should be the one running on the bike - the better one will then get you at least back to where you started if the worst one fails ...

Take the Hall sensor and the clutch actuator arm . The Hall sensor will not be something you can easily get hold of in the back and beyond and will leave you stranded . they can fail without warning. The clutch actuator arm is the bit at the gearbox end of the clutch cable . They can snap and without this you have no clutch - they are small and lightweight and if I had a spare I'd carry one having been stranded once already because of this failing.

I'd add at least one of the awful half size relays BMW use in the FI pump power system. Bosch ones are best as they have the right resistance but any will do. The alternative is to rewire for the full size jobs you can buy anywhere. I learned this one the hard way!

I guess you know it's pretty pointless to carry anything you don't know how to use?

Aside from routine service items.

For third-world I'm carrying:
  • Alternator belt
  • 2 Spoke sets rear and front cross-spoke wheel (if you've got spoked wheels (which are much better than the alloys) )
  • Injector heads (if they get worn, stop working (electroncs!) or just get clogged with bad fuel)
  • Spare fuel filter (existing filter is already routed outside the tank - much easier replacement)
  • TPS unit (not that necessery, but I nearly broke it once)
  • Hall sensor unit
  • Spare "emergency" cable set with end adapters (NOT complete cables with necks, but only the thin inner cables for temporary use, they don't take the huge space and don't have any fitting issues with stiff necks etc)
  • Spare clutch cable (which is already strapped on the existing clutch cable with quick straps - if it breaks, just connect the ends of the new cable and you're ready to go, easy as that.)
  • Main final drive crown wheel bearing with some spacing shims
  • Final drive main seal
  • 2 spark plugs
  • Motronic 2.2 fault code tester (15EURos from eBay, takes very little room)
  • Rema Tip-Top tubless tire puncture repair kit
  • A manometer and a compact bone-powered bicycle pump (not some ugly electric compressor taking 1/5 of your pannier!) to keep your tire pressures OK between dirt and tar and your muscle strenght good.
  • 1 litre of oil for the engine for regulary filling up the oil consumption, 1 litre of transmission GL5 spec oil for the FD and gearbox you may find hard time finding it in the third world for the GL5 spec. Good to strap the oil bottles outside the panniers. Although the actual service interval is 20K, transmission oil you may need prematurely when crossing deep rivers etc and some water passes through the FD vent making it a "coffe with milk" emulsion.
  • And the two a must classics: a small bottle of WD-40 oil for the stuff that doesn't move but is supposed to...
  • ...+ Duct tape for the stuff that moves but is not supposed to
  • A small bottle of RUM to keep your spirit high when the reality pushes you down the train (not to be combined with riding your bike and in muslim countries, please!)

For western world: just take your credit card
