Re: First run today!
Congratulations, Toothy. You're on your way to lots more fun.
Not sure what "poppy" means but as long as the engine is secured to the frame well and runs good you should be okay. Can you explain "poppy"?
25:1 is alright but you'll have many tell you to drop your oil content down to about 32:1. If the engine was used then it is a good bet it has already seen some run time and can be considered broken in. A good idle is also good news. That probably means no air (vacuum) leaks to worry about.
Have fun and ride safe.
