I've had this kx65 for a while now and it still runs like crap. I've rebuilt top and bottom end with wiseco. Also had the cylinder replated and resurfaced by powerseal usa. New plug. New everything. When I crank it, it takes forever to get it to finally crank and once it's actually running, it has no power and is super slow and just doesn't run right. I finally got tired of figuring it out and took it to a shop. They set timing, did leak down test, compression test. He said that the crank is 0.008" runout and bound. He said that's my problem. Would that cause it to run like this? Compression is 155 psi.
