Hey guys I have a question for y’all. I didn’t change my tps settings before I had my YFZ 450r dyno tuned. Now it’s having a hard time cold starting. It won’t even start unless I give it throttle. If I change my tps to .689 is it going to change the way the bike performs?

Changing your TPS voltage will change the fuel curve slightly but cold starting issues are more likely valve lash issues over idle TPS issues.
