Scratching my helmet

The two hex screws inside the storage compartment has sharp edges that persistently scratching my helemt. I have ti put some foam tape to fix it.

Airhorn trigger

More ergonomic than the stock thumb button. Left index finger can be used to fire yhe jorn. Thumb was left to have a tight grip of the handlebar  during emergency brake.

Compare stock 20W bulb and 10W (3W measured) LED

 
The stock looks more amber and diffuse and the LED (No lens ) looks more centred and cool.

Add horn switch to DCT

DCT  version free your left hand. During emergency stop, your left thumb will be busy in gearing down, switching on hazard light etc. I found it is attrachtive to add a horn switch to left index finger, so that the left thumb can keep maintain a tight grip on the handle bar. This is room inside the switch hub and you need a knife to get away enough plastic to place a tiny microswitch.

Yellow 7.5w signal led

Benchtest current drawn 180mA only, that is 2.3w only. Claim to be 7.5w (1.5w x 5 led ). Right is led. Left is stock bulb.

Brake light LED

Replace 20w bulb with a 3w (claim 10w T6) white led. Benchtest with 13v and current drawn is 200mA. Brightness is same as as stock without a yellow tinge. The right signal lamp is yellow led (looks like having a transparent cover), wheras left is stock.

LED Flasher Relay

NC700 use Mitsuba FR33-025 as signal flasher relay. It has 4 pins connect the 2 hazard/turning indicator switch and the left/ right bulbs. Changing low load/watt led will give the realy a wrong signal that the bulb filament is burnt and results in faster flashing rate. The easiest but an unwise way is to put a serial 10W resistor to comsume excess power. This defeats the benefit of using LED. So you have to use a dedicated flasher relay or mod the stock relay. The relay has a load sensing circuit that kicks in alternate circuit results in a faster flashing rate if the loading current decreased. So one have to trick the sensing circuit inside the relay, by increasing the resistance in the shunting wire/ resistor . This cause more current to flow through the current sensing circuit.

This can be achieved by
1) Dremel the thick shunt wire inside the relay, or replace the bare wire with a higher resistance 3W 0.1 Ohm resistor or 3A diode.
2)  Cut the sensing circuit, but this requires more knowledge of the circuit



Sample stock relay

Sample Mod with resistor to trick the sensing circuit.

Clear signal led mod

Looks more fashion..

Reduce the rear shock preload

Stock setting was a bit hard for single  rider of 60kg. Adjust the top nut anti clockwise by 2~3circle make a huge difference. Now no more ass kicking over bumps.
U need special wrench , or a long screw driver and a light hammer.


Givi Monokey FZ1111 & M5 plate

Easy 15minutes installation. Hex key 5,6mm. Wrench 10,14mm. My Givi set has missing  four M8 hex nut in the bag. So check it carefully.
