I am new to this forum so here it goes. I have been a two stoke guy my whole life but came across a deal last summer on a 04 kx 250f that I couldnt pass up. According to the seller the top end was rebuilt and stage two hot cams were installed. So I didnt really get to ride the bike very much last summer and wanted to check the valves to make sure they are in spec before the riding season this year. The bike did run but the carb needed cleaned so I just finished doing that. Ok so to my question that hopefully someone can help me with, when I removed the I guess valve cover it looked to me like the timing marks were off on the exhaust side of the engine. I watch a few youtube videos and they said the dots should be at 12 and 3 on the intake side and 12 and 9 on the exhaust side but they looked off to me like a tooth off on the exhaust side. I thought the side dots are suppost to align with the case. Would it still run if it was a tooth off. Can anyone verfiy that they are off? Also would I have to correct that before checking valve clearances? Thanks for everyones help. I have attached a photos of it.
