Any chance it switched to 2 stroke?

I don't think so didn't change any settings

How many RPM's do you believe you're turning when it reads 3800? Where are you picking up your RPM reading from?

6800 that was peak rpm for others on same gearing... I know what gear to be on to be close just don't like not having rpm
