Tested & True: GY6 Performance [The Dyno]

November 2019 Forum Retirement
Due to lack of extra personal time (and too much spam), I'm retiring the forum and setting it to a read-only state. No new registrations or posts will be accepted as of 11/09/19. However, all information will stay up and searchable. If you spend a few minutes searching, you'll find the answers you're looking for. We may re-open the forum next spring.

Can you tell good performance advice (from snake oil advertising) when you see it? There are many GY6 performance myths invented by sellers, meant to part you from your hard earned money. It may sound good, but is it tested?

Ask your engine upgrade questions here. We'll provide tested answers.

We're building our own GY6 DYNO (dynamometer) with full CNC control! Subscribe to the dyno build thread to stay updated!
