Gunson Colortune / 14mm Adapter

Post by Dr. Frankenstein » Sat Aug 26, 2017 6:17 am

Does anybody have a Gunson Colortune, and does it work?

The concept looks pretty cool, and everything online is inconclusive, but after much research I pulled the trigger anyway.

I bought the 12mm one, which should fit my CA's, but I don't know if I need a 'long-reach' 12mm one for the CA's I have; any ideas?

Does anybody know the difference between a 14mm and 14mm 'taper' adapter?

I'm also hunting a 12mm into 14mm adapter for the aforementioned Colortune, if anybody has one they don't want or need.

Did you buy it from an Antique Shop?

Seriously I'm amazed that they are still around, I had one well around forty-five years ago, bought it to use on my van, couldn't afford a car back then.

From what I recall, the results ( indications?) were pretty inconclusive and don't remember what I did with it! Never tried it on a bike, can't even remember if I was riding one at that time. Let us now how you get on with it, perhaps I should look round and find another 12mm one as I still have a Cb77 and CL77 in the garage!

Member 'spargett' (Scott) has used one with a fair degree of success. Suggest you PM him...

Thanks guys, I will...

No, DJM, they're still making them. I ordered a 12mm for my CA's, but of course my other bikes take a 14mm spark plug, which they either don't make anymore or are hard to find; and I just picked up an inline-four '78 KZ650, so I'm thinking I'm going to need one.

They look pretty cool, and seem (according to research) take a lot of the guess work out of where to put the A/F screw, so I thought I'd try it.
