Digital Motorbike ammeter – Installation on an F800 ST

With all my charging problems I have wanted to install an ammeter to see if the battery is actually charging, as you can only tell so much from the voltmeter.

I spotted a small cheap ammeter with a shunt, the was capable of 200 amps measurement.

It was also very thin and fitted in the center panel perfectly. I have now officially filled that free space!

The last picture shows my charging system generating 1 amp of charging current at idle.

BMW F800 ST Projector headlight installation

I have recent part exchanged my FZS600 for a 2007 BMW F800 ST. The BMW is a lovely bike, but has had a fair few things go wrong with it already, so stay subscribed for lots of posts on how to fix various things on it!

This is a post on how to install projector headlights. I am a big fan of Xenon headlights, but hate blinding people with xenon bulbs with halogen optics. To get around this, the best way to install projector optics inside the halogen housing.

I have done this for my Honda Varadero, my FZS600 and now my F800 ST. The details will be pretty sparse, as I covered most of the required steps here and here.

First was to buy the projectors. I always source mine from from ebay china sellers, but some people like to pay extra for well regarded optics, in which case, I can reccomend the morimoto projectors.

Next is to split the housing, insert the projector insert and sort the wiring. This is all covered in the older posts.

I also swapped out the sidelight bulb with an led bulb. I wired my HID ballasts through the original sockets, to keep bulb warnings from showing. I also used a high/low projector with a solenoid inside, giving me 2 bulbs worth of brightness at high beam.
