Hi guys my father has a 2006 suzuki Eiger 400 that was always garaged and mint with 600 miles. So it’s always ran well until the other day I opened it up in a field and it backfired out the exhaust and stalled out in 5th gear. I’ve sense drained the gas, replaced the suzuki petcock, soaked the carb and cleaned it 5 times and it’s spotless, adjusted valves 2 times, checked the flywheel magnets and they’re perfect, and I’ve also tried a Chinese carb and a new OEM $600 carb and it revd up better with the Chinese carb but wouldn’t idle and the OEM carb acted just like the Orginal. It’ll fire up but just keeps backfiring out the exhaust and the plugs white so it’s lean as can be. Idk where to start next, maybe a leak down test or vacuum test?
