I have about 3 gallons through my Reedy so far and I don't have any bearing leaks or anything like that. I've noticed that this engine does have a small window for an optimal tune and runs a bit hotter than some other engines. I was running P3 and P4 plugs, but I'm going to try a 97T this weekend. I'm also planning on changing the bearings and rod in another gallon as a precaution.
I also have tried a few different pipes and like the RE11 the best so far. It really brought the top end of the engine alive as opposed to the 2035 and 2053. I'm getting about 8 minutes 30 seconds out of a tank. I'm still not 100% in love with this engine, but for the money, it has been good so far.
