My friend bought a 2016 250EXC with 8 hours on. It has an issue where it dies if you give it throttle at idle, or bogs down and dies at low revs. You have to adjust the idle right up so the bike will throttle / accelerate properly. I know these have fine mesh filters, which he says are checked and clean but he's done some research and it appears there are many people experiencing the same issue, (not just on 250's either) and that theres a way to adjust the TPS. Is adjusting the TPS how the A/F ratio is adjusted when you get a bike tuned? Anyone had a similar issue or have advice i can pass on?
