Neville,
Nels is honestly a freak in how quickly he can do a tune, it’s ridiculous and I have no idea how he’s able to dial bikes in so quickly. Not just the rocket but bikes in general. I’m sure it has something to do with the sheer number of bikes he’s done.
Thank you for your input. I am indeed literally using the road as a dyno.
For everyone else:
I 100% do not encourage or condone anyone doing it. It’s a terrible idea and a very easy was to trash a motor or have an accident. I’ve been doing it this way since 2004 and STILL say it’s a bad idea. There have been a number of “incidents” that were near wrecks/trashed motors over the years. I only learned to street tune because of necessity, and I still use shop dyno time to validate my work.
