Colortune sparkplug in a Bandit 400 engine

[Herr Tod]

It's a 'Farbtune' actually, which comes as a 10 mm plug without the need of an adapter. Just made this little movie after warming up the engine. You're looking at a mirror above the sparkplug, YouTube messed up the quality though otherwise you could see a blue flame all the time, except when opening the throttle, it turns orange for a second then. Had to go easy on the throttle though because it was 10 in the evening I need to lower the needles a bit, but I knew that already.

So, how well did this work?  Was it worth the money?  
Thanks.

It wasn't worth the money, a year ago it was but now I know how to recognise things and adjust the carbs accordingly. However it can also be used to see if there's coolant or oil inside the combustion chamber. Works great, very clearly visible with the eye, the movie is crap lol.
