This may be kind of a stupid question, but what are the signs of a soft seize? Does the engine just bog down? Is there a certain noise to listen for? I'd like to be able to recognize it if it happens so I can shut the bike down before I do too much damage.
yeah it can bog down or completely cut off,most soft seizes will kill the motor. Do you think you are soft seizing or you just looking ahead but if you do try to let motor cool for a minute before trying to restart it

A few times I did have the engine bog down and die after climbing a long hill. It happened only when I was using really cheap crappy oil. I'm using synthetic oil now and I haven't had that happen. In fact, I just did a 30 mile round trip at or near WOT the whole way including some big hills and the bike didn't even sputter or bog once. I don't know a lot about the quality differences in 2 stroke oil. Can low quality oil cause a soft seize, even if it's mixed properly?
Any two stroke oil is good. Synthetic is just a waste of money. 50 engine hours after installing my Stage 6 race kit (Zuma), the motor ran like new still (running Valvoline weed wacker oil).
To answer the author's question, I soft siezed my old Zuma twice. Both times it seemed like it was running really good for 20 minutes+, then it bogged for a mile or two, then didn't quite sieze (piston stuck in cylinder), but definately let me know to stop trying to go and shut it off. If you think you're at risk, get a bigger main jet.

Oil does matter. The oil for weed wackers us thicker than oil designed for oil injection scooters. Really. I use synthetic or synth blend. Cheap oil not only doesn't lubricate as well it leaves more deposits. So if you like pulling your head to decoke it by all means use the cheap stuff...
