I have a set of these, not used em yet... if they work on 2Ts then im game, but the oil might mean the flame isnt the same colour?

I doubt the oil would make all that much difference.

By the way - it won't avoid a plug chop.
All it will do is get your idle/light throttle in the right area.
Theres no way you could use this for full throttle runs.

Could you do it on a rolling road? Or does it just not work that way?

Its always been about the low speed running, I used this to sync and tune my Triumph Spitfire carbs in the 90s, happy daze LOL!

Maybe, but I would be VERY surprised if the glass held up to the temps, or whether the plug would continue to work properly under that load.
