You need an infusion kit, some 25mm aluminium strip 1.5mm thick and about 5" long, a nose plier and a drill bit with a 10mm bit. Apart from that, the oil dispenser. I'm planning to use an oil can later, right now, I'm feeding it through a syringe.

How to:
  • Roll one end of the strip such that the tube of the infusion kit passes through it (get rid of the needle).
  • Bend as shown in the pic below and use the nuts and bolt at the end of the swingarm cap to fasten it after drilling the 10mm hole at the appropriate place.
  • Using the left side footrest extrusion, secure the flow control mechanism. On Indian CBRs this can be wedged between that and the saree guard, else use cyanocrylate adhesive and tie wraps.
  • Take the tubing diagonally upwards into the fairing such that it come out somewhere near the tank. Please note, it should feed properly with gravity!
  • Connect oil source/alternately push in about 5-10ml oil with a syringe after every fuel stop as you get underway

A few things to bear in mind.

  • The syringe can be a large capacity one, but if possible try get one with a plastic plunger as rubber plungers and spent oil are not the best of friends.  Inject the lube just before starting off.
  • Adjust the flow control such that the oil takes at least 20min to empty, too fast and you'll have one messy rear wheel.
  • Secure the other end of the pipe without kinking it or blocking it after injecting the lube, unless you dont mind it dribbling all over your bike as it drops down somewhere onto the crankcase instead of the chain, remember, gravity is doing the job, let it act in the right direction.
  • You can use any oil as you will be lubing the chain very frequently (every 300km or so). Spent engine oil/90W oil all these will work as the lubing is being repeated very frequently, courtesy the tiny tank.
  • To keep things from getting messy, inject a little AIR into the tubing after you inject the oil, so that you are dealing with an empty tube (at the top when you are securing it, not one filled to the top with oil.

I think you can see the saree guard mod as well, which makes for an improvised luggage rack, designed to carry heavy stuff like your tools etc, which otherwise are a royal PITA as they are heavy and have the potential to tear through bags and damage paintwork.

The bending is done on a press, and the bends are reinforced with welds subsequently as the tube gets squashed  and is therefore a weak point

Well "Safiqr" This particular Mod (Chain Oil Lubeing) is basically for the Heavy Duty Tourer (eg. DOC), wherein the necessity to keep the Chain Well Oiled and properly functioning through a Majority of Indian Road Conditions, is a major priority to lessen on road hassles. For the Regular City Usage, a Spray is Sufficient. But during Longer Runs, the Chain goes hot, and drinks oil like a Suckling Baby. and thus the requirement of an Artificial Mammary Gland to hold the necessary Supplements (in this case Lube Oil) ;)

Also in addition to the above, explained so lucidly like CV, the syringe setup makes chain oiling a 1 minute affair, which, otherwise on the CBR (no centre stand) will take at least 5 minutes. The syringe is also a lot less space occupying than the oil can. A dry chain can get easily damaged on long, fast runs as the oil dries out. Even with a long range tank, once a dispenser is fitted, the oiling can be done on the fly, no stopping required, so it's very convenient and there's no need to bother about having to stop the bike, fish the big can out, spray bit by bit in the hot sun while moving the bike forward so as to oil the entire chain.

As you can see, this complex time wasting process (spraying bit by bit while moving the bike forward) is avoided.
