I have a 2016 Cheetah with a 31 Kawi (carb) on it. I dropped it off at the dealer for some warranty work, and to have the backfiring checked out. I just assumed the valves needed to be adjusted - quick fix and back home with it a couple days later. When I called today, he said he was talking to Kawi reps about a couple of possible causes and solutions. I'm in no hurry to get it back as the season (for me anyway) is over - I just can't put my trailer away until I get it home and cleaned up. So I'm not dealer bashing by any means. I like my dealer and the guys who work on my machine - I told him no rush at all. Any idea what else would cause the backfiring? It usually happens after I complete an account. The faster the engine is running when I shut down, the louder the "bang." If I am idling as slow as it'll go, it sounds like when the dog farts on the coach. When I started it in the shed last winter, it sounded like Uncle Buck's car (not sure if anyone will get that reference lol but it otherwise ran perfectly all summer. I did use a lot of gas, but most on here seem to agree it's a guzzler, so I didn't think anything of that. Just curious to see if anyone has some insight. Thanks for any input!
