[@brianwells5258]

Yes this is what I was telling you about Mark... Gonna try it on my MJN carbs as it will Immediately tell me if they are running rich and I can adjust accordingly ! 👍 Old School....,and I love it.....,suits me just fine !

Great demonstration of the colortune kit. I can remember these kits from way back 😀. Your ZRX is certainly running beautifully. Thanks, Brian 😊 👍

[@brianwells5258]

Many thanks Edmund.....,yep I remember old tuning shops using them too ! "Old school" is right up my street...!

[@krismorgan]

Excellent,thanks for that.

[@marktipton412]

Sounds great. I've never seen or heard of Colortune before. I like it. Kind of reminds me of a oil furnace.

[@kevinstreet5709]

Thanks again mate

[@brianwells5258]

You bet

[@ohwowawesomegreat]

Keep these coming this is great!

[@bertrandrussell2549]

great videos👍. do You use this to set only pilot screw ( idle mixture) or also to set needle hight (middle rev range) and main jet size ( high rev range) as well?

[@brianwells5258]

Thanks.,I mainly use it to set "burn" via the pilot screws (mixture screws) Here is another video from another creator using it on an old 1978 GS 750.. kzbin.info/www/bejne/Z4rcYX1_mttmmJIsi=ORcDODh-6ddYwVFA It's an invaluable tool for me ..👍 BG.

That is pretty cool. So how well does it actually work? I am see the philosophy 👍

Never had them in the US, strange we like this kind of thing
