Dax,
That doesn't tell us much because your warranty period is only 30 days. I'm wondering how many, not just your engines, fail later on down the road. I doubt most first time engine buyers get much riding on their engines during the 30 day period.

That's a good amount of money for a Honda piston and ring. Its a good thing that Hondas are very reliable. I've owned 3 Honda motorcycles in my life and they were extremely reliable except for an 84 700S nitehawk that had a starter clutch fail requiring me to split the engine case :-(.

Anyway, it was a boygofast engine. My Dax bushing engine had no problem going full throttle down the same hill. I've got numerous small 2 stroke engines that are being engines that spin up to 30,000 rpm continuosly with never a bearing failure. I don't think the stock bearings are up to snuff. Chinese metallurgy still has a long way to go...remember it wasn't too long ago that the engines had pot steel engine mount clamps that sheard when you torqued them down.
