I do get crazy I can't get the bike to run lean

Easy (?) on a roadrace bike where you can pin it open for many seconds on backstraight. But only if you pull the clutch at the end and push the bike back. Ride it back and you have invalidated the reading. And everybody does that.

I agree if someone isn't going to do it right then a plug chop is useless. I know to not ride mine back and I know most anyone serious about jetting knows this as well. I literally carry a plug and wrench to change it out after I stop. Yes, along side a dirt road I actually change the plug. When I get back to my truck I cut the plugs open right there on my tailgate, make adjustments, throw in another new plug, and do it all again.

Now, about having room to do it, I don't know how things are in NZ but in Arizona I can run a bike pinned wide open for miles, all over the state, so room is not an issue for me.
