howdy, since no one else has answered, i'll give you an opinion concerning what you said in your last post. the problem that allyooop referred to wouldn't be the valve sticking but when all the metal parts have expanded from the heat, the valves will not completely close which results in reduced compression and eventually will cause damage to the valves, stems, and seats. ---and cause the engine to be hard to start and run poorly when hot. lotsa miles and smiles to ya ken That makes sense. Will adjusting the valve gap fix this problem? It's starting to happen more often now during my rides. |

Thanks guys for the replies. What alleyoop said does make sense. Since I don't always get this problem consistently. It is really random and only once in a while. My gy6 engine is brand new. Had it for about a month now. I been following the break in procedure for the first 50-100 mi of alternating the throttle and not wotting it all the time. What's the stock valve setting for both intake and exhaust? So a really tight valve that sticks can cause the backfire problem with immediate engine dying upon start? Because it is stuck in an open position, causing a loss in compression. Then once it cools down for a bit the valve will unstick? And by loosening the valve a little bit, I won't have this problem anymore. Is my logic and understand correct? Thanks again!

This has happened to me on two separate occasions probably a month apart. I was wotting it down a flat street when all of a sudden I start losing power and when I came to a complete stop the engine just dies. Any attempts of trying to start it back up doesn't work. The starter does turn the engine freely, just no combustion I checked he fuel pump and can see file flowing to the carb freely. Gas tank is still half full. Carb was cleaned only a few days ago. No debris in float boat or clogging the jets. Vacuum lines are fine and not clogged or loose. No leaks either, as evident in me being able to ride after letting the bike rest a few minutes. After chilling for about 5 min, I can start the bike up again with no problems and I can still ride as if everything is fine. Nothing else changed. I have no idea what the problem is. There are other days where I am wotting all over my city for around 1 hr and have no problems whatsoever. This is a rare occurence but it has happened twice so far. Is it a faulty CDI? Am I overheating? Though I rode it much harder the day beofre without problems. I have no clue. Thanks for any help!
