Kimjon's Harley bobber project


Recommended Posts

Long story short, speedo driver unit for mechanical drive, adapted to fit a late model wheel that doesn't have mechanical driven speedo.


Problem was this gap. The older shovelhead wheels have the bearing recessed in an inch, so that tab connects.

Also they are mounted on the RH side. Mines on the left.

Then drilled a 4.5mm hole into my headlight and put a small but very bright LED light in there, just below the high beam indicator light.

The oil pressure switch is wired up to this LED. so if oil pressure is low it will light up the LED.

The positive lead goes to the light filament (center contact). The ground portion of the light bulb goes to the switch (oil pressure sending unit). The switch is normally closed. Turn ignition on and the "OIL" light comes on. Start engine and the oil pressure "opens" the circuit, making the light go off.

More shit done. This remote oil filter has been a total pain in the arse the entire way through this build. Ive never found a great place to put it, plus each time I do, it ends up in the way of something else later on.

So I think I've found a new home for it:


Brackets getting made




Boom!! In position, nicely hidden behind transmission.

It unscrews with room to clear the belt, frame, transmission and fender. Any oil should fall straight down (into a waiting catch pan) with nothing in its way. So I think this may be the best place I've tried to date?

Then I looked at the oil tank. Brand new item...removed caps...full of rust, metal filings, all sorts of crap and corruption inside the tank.


I did 5x rinse outs with petrol. Used about 10L of it. I figure $20 of gas is cheaper than 5K on replacing fucked motor.


Here's some of the shit that came out.

Harleys have a gravity fed oil system. The filter is on the return line as this is under pressure. The fed line is unfiltered, no oil pressure until the pump.

So if I started with shit in the oil reservoir it would go through the motor first!!

Im a little concerned if the bolt ever fatigued it'll drop onto the tyre. But I think it should grab and rip it out clean...???

The wire (which will be retained inside the fender) will also help hold it in place if it did snap and fall down a little, so maybe I'm over thinking it.

I was going to do spot welds, but that could cause alignment issues, as the  bolts don't quite sit square on the inner fender. Think I'll just send it.
