Alright, I'm sure you guys are getting sick of my "broken blaster", "jetting", and all my other posts but I'm getting sick of it breaking lol. So today, went riding, just breaking it in, going easy on the back, mostly half throttle, varying RPMS, bike was running good and at one point I got on it a little harder and it just shut off and came to a sliding stop. I kicked it again and it started right up so I just babyed it back to the car so I could disassemble the head and see what was going on. I had just re-jetted it with a 270 main, moved the needle to the middle and adjusted the a/f screw for the idle. When I was taking it apart I found that the breather tube on my crankcase had melted closed on the exhaust so I cut that off. When I got the head off I took pictures of what I found, vertical lines in the cylinder but you can't feel them, at all. The cylinder wall is nice and smooth, it was just bored .060 over and has a wiseco prolite piston. Are these lines normal? Should I worry about it? I have rejetted it again to 330 and moved the needle up 1 more click so it should be super rich. The bike has a pipe, silencer, intake is just a 3" piece of hose with a k&n on the end, not even under the seat so its probably getting lots of air. Plugs are a nice dark brown so I'm really lost as to what it could be. I have included pictures, any help will be greatly appreciated. THanks guys.
