Small side project. Replace the annoying and letís face it, notoriously unreliable 4 way connector to the fuel tank and put it in a more accessible location so that I donít have to remove the sides to get the tank off

Finished the handlebar upgrade all the switches are wired and working, with the wires running through the bars. Iíve also fitted new levers, master cylinder and brake hoses. The brake switch has been replaced with a pressure switch at the calliper. I have managed to retain all of the original functionality including the self cancelling feature.

A few pictures and a video below.

Those switches look nice and clean. Are they made by MotoGadget?

In Answer to Milq and another question asked by sr20clubbie

The switches are not Motogadget just ones from ebay. I wanted to reduce the size of the cables as I was running it through the handlebars. I also decided to only have switched negative reducing the chances of shorts in the switches and lowering the voltages so I used a 4 way relay board and switch the starter, high/low beam and cutout switch through that. I also fitted a changeover relay for the cutout as the cutout switch is momentary. I wanted to keep the BMW flasher unit as I like the auto cutout function as I'm lazy and have been known to leave my indicators on.

The Choke lever is from a Motoguzzi V11. i used all the existing BMW cables but had to make new cable end on the choke. It all works great.

sr20clubbie I used a set which are common on e-bay. However I had to make alterations to make them fit to the switches. I cut off the mirror fixings and repainted. I also did away with the brake light switch and replaced it with a pressure switch on the front callipers.

I was also not sure whether the brake master cylinder would be man enough but itís better than the oem unit

Hey Skunky, I actually meant what bore size. Most of the aftermarket ones I have seen are 14mm, I think I need a 19-20mm bore size (correct me if Iím wrong) did you get rid of the abs system?

Cheers Paul

I have rental bars on mine which have the smaller bore and I changed the rubber on the bar ends to make them fit. You can get indicators for 22mm bars. My bike did not have ABS fitted. But plenty of guys have removed theirs.

Due to the Pandemic I seem to have a lot more time on my hands lately, So after completing the Handlebar Switches I started looking at what else I can improve.

When I finished the bike in 2017 the mechanic at the MOT centre did not like the rear strip light because when the brake lights are on the integral indicators do not show up. So to make him happy (and keep me safer because he was right) I fitted a pair of mini indicators either side of the rear tail unit. Problem solved.

So why does it still piss me off!. Even after recently fitting bar end indicators I scoured flea bay until I found a light strip where the supplier claims the indicator sections are still visible when the brake light is on and ordered it.

Although slightly thicker meaning I had to make a subtle adjustment to the rear tail piece it actually works. I have taken photos of the old and new lights strips but because of the glare it doesn't look that different in the photos. So heres two pictures that look almost the same  :laughing4-giggles:

As an extension to the handlebar project. I decided to make switch ikon but the print sheet is so big I thought I would make my own tank badges to suit the Skunk theme.

Wondering if you can draw the diagram of how you connect the switches, could you please take a picture how you connect the brake switches, thanks. The bike looks nice with all modern accessories. 112350
