Mate, I've just done this. Have a look on the site for a good set up. I'll see if I can get some info and piccies for you tomorrow.
Thank you
See pictures below for my set up. You can get the Feked item or the Magneto Guys unit, but I got the Feked unit off Ebay for £24. For the Feked unit, I used a couple of 3/8" to 1/4" reducers on either side of the valve. I then rerouted the original oil pipe through the engine plates and screwed the pipe on ( the 90 degree bend on the pipe is very helpful with this and you don't have to cut the pipe at all).
On the oil tank side, I used a 90 degree elbow with female fittings. As you'd have guessed, this screws onto the oil tank and the other side of the valve (opposite side to the oil pipe, of course).
Adapters and elbow were about £10 off Ebay.
In the pictures, it may seem a bit busy as I located my spin-on filter in the space where the ski slope would go - it all seems to work fine though.
When finished, I'd recommend bleeding the oil through the pipes at the crankcase end initially, just to ensure there is no air lock. The feed works on gravity (and maybe a bit of suction through the pump when running), but the flow is notoriously slow (as someone put it, 'like a bit of honey running off a spoon') - and very slow when cold with thicker oil.
You can seal your threads with PTFE, but be careful you don't get any in the pipes. I didn't use much tape at all (oil tank only) as the rest seems oil tight.
CAUTION - the pictures on the Feked website show the position of the lever in odd positions. I have found that the white, plastic plunger has to be DEPRESSED to engage the earth and not allow the bike to start, when the oil lever is ON, the plunger should NOT be depressed (see pictures). CHECK sparks at plugs during set up to see when maggie is earthed or not when lever is in both off and on positions. I got this wrong initially due to the error on Feked's site. When I asked them about it, they said they'd just taken a picture of the unit and had not noted the correct position of the lever!!
