This is effectively a glass spark plug. Colour tune has been about for years and is a very simple, yet effective tool.
You replace the standard spark plug with colour tune and then start the engine. You can actually see the colour of the burn inside the combustion chamber. If the flame is very yellow then the fuel mixture is running rich. It's no substitute for a proper dyno run, but it is fabulous for diagnosis.
Sadly this super useful tool has been out of stock with the manufacturers for a long time, but when they return, we will buy some stock immediately

Great tool, so easy to use and a perfect crimp every time. Should have bought this tool years ago. Well worth the money
Always brilliant, just when you think all is lost "Bikers Tool Box" saves the day. Thanks.
exactly what I wanted No more stripped out screw heads Will be using them shortly
Bloody good piece of kit, expensive because I had it shipped to france, but worth it, plus I got another sticker and some sweeties 😃 would recommend
Although at the budget end of the range, a great vacuum brake bleed tool. Easy to use with lots of adaptors to suit all types of bleed nipples and plenty of tubing. Huge thanks to Ralph for sorting everything with this order.
Superb product. And really helpful advice from Bikers Toolbox.
I needed a couple of things confirmed. They had the answers immediately!
Definitely use them again
To begin with I struggled a bit to get a perfect closure of the pins, but I haven't got the best pliers, just a cheap one. It took me some time to figure out which way to align the pins in the plier, when I figured it out it all worked fine.
fantastic, much better than all the others I have tried.
A good quality bit of kit delivered quickly. Just what I needed.
I was struggling to get the brake Piston out of the housing. Bearing in mind it was 21 years old and sized solid, I thought it wasn't going to move let alone come out. his tool after trying all of my normal tools which which failed, I ordered these. It was still a struggle, but I got there in the end. An impossible task without them
Always good to deal with bikers toolbox. I modified this fuse holder to upgrade to blade fuses on my 1977 honda 4.
