Gas Float Problem

You find yourself filling your motorcycle gas tank full and yet the fuel gauge indicate an empty tank? Why not check the fuel float bowl for the reason that the float switch is always dip into the gas corroding the contact. You already check the wiring and find no problem, check the terminal and connector but still in good condition, and you thought of checking the fuel gauge for problem but still in vain, it is time to check the FUEL FLOAT inside your gas tank for intermittent and or contact problem.

Due to the fact that the gas nowadays contain alcohol content, to which causes some problems on fuel lines especially rubber that gets harden and fuel float sensor that gets corroded.

6 Volts Motorcycle Regulator

This circuit was modified by a friend (Tom ) for his 6 volt honda vintage bike CT90 that was needing a voltage regulator. He derived this from my previous post of 12 volt single phase motorcycle voltage regulator FULL WAVE. With only minimal changes with the values created the hard to find regulator for 6 volt charging system.

CIRCUIT CHANGES and description

Use:6 volt Regulator Rectifier for 1976 Honda CT90 (permanent magnet alternator)
Base circuit:"full wave regulator" single phase  12 volts regulator
Circuit mods:Results were collected with the following modifications to accommodate a 6 volt systems:

R2 & R4 values = 470 ohms
C1 = 22uF 50v
SCR's = S6025L 25amp 600 volt Heat sinks a must even with short testing
Bridge rectifier = purchased 35 amp 600 volt AC, 1000 volt DC

Zener diodes as shown below
R3 values as shown below

Regulation output as shown:No load & Headlight on

With zener 1N4733 (5.1v)various RPM's

R3 2.7K ohms 6.6v stable    5.9v +/- .25v load.
R3 3.3K ohms 6.9v stable    6.3v +/- .25v load
R3 3.6K ohms 7.1v stable    6.4 +/- .25v load

With zener 1N4734 (5.6v)various RPM's

R3 2.7K ohms7.3v stable   6.6v +/- .25v load*
R3 3.3K ohms7.6v stable   6.9v +/- .25v load
R3 3.6K ohms7.8v stable   7.1v +/- .25v load

Thanks to Sir Tom, cheers mate.

Aluminum Color Remover

More often when we buy motorcycle aftermarket spare parts, we come up with such like aluminum or anodized aluminum with colors, and very few are original aluminum. Anodized aluminum actually is made to just increase natural corrosion resistance from other chemical, but then when the dye color fades due to wear, looks degrade heavily. So why not remove the color and surface the real aluminum color out of it. Let us take for example the picture on left is dye with BLUE color. There are now areas with faded color, We want it to look nicer so we will take out that blue color to
