So I'm maybe 100 miles in on my new build and the engine starts knocking. I ran 16:1 for the first gallon, then the second gallon was 20:1. I ran it pretty easy hoping for a proper break in and long engine life. I took the top end apart first and noticed that one of the head bolts had pulled loose and stripped itself slightly. Would this make the cylinder uneven enough to cause scoring? The gear puller didn't come in my kit so I had to order one. I got it yesterday and took the bottom apart. Everything looked fine, the bearings didn't roll very smoothly. I ordered new SKS bearings, surely that's gotta be an upgrade right? I sent pics to bikeberry and they told me this didn't look that bad, so does that mean I'm supposed to reuse this, all gouged up like it is? He wouldn't warranty it and wanted to wait until I got the bottom end apart to see if there were problems in there? I asked hans at bikeberry to meet me in the middle and send me a replacement cylinder and head, I had already ordered a piston kit and a 15mm wide wrist pin bushing, seal kit, new carb, and SKS bearings. I haven't heard back but I do realize its Saturday, maybe they aren't open today. Seems fair to me tho. What do you guys think? Can I reuse this cylinder?
