I was heading home. Prob a min away from home. I was on the back dark roads with round abouts and no lights. As I was coming out of a round about I was opening my throtle to straighten up from a leaning to the right to leaning to the left to leave the round about. When I started to lean to the left my head light picked up somthing on the road. It was a piece of wood(abt 20cm x 4cm x 10cm). It was directly in my path. I felt I was in a position that I couldnt do anything in the fear of coming off or running off the rd. I decieded to run over it since I couldnt avoid it. Only the front went over it and the handle bar flicked but the front end was still straight and I just rode off. After that I kinda slowed down down and think what happends if I get a flat tyre. I got home ok then I checked the front tyre. It was fine. Nothing out of the usual. I then said ill check it 2mrw and c if its ok. I was wondering if there's anything I could have done to avoid something while u were starting a lean? I had only abt 4m of warning going at 50ks. I was abt to turn my high beam on but kinda for got and thought Ill turn it on after and thats when I jus hit somthing. I went bak to hav a look at what I ran over. It was a peice of wood that they used to construct houses with. There wernt any nails in it so I think my tyre is ok. In this case if I get a leak is there a way to fix the tyre or do I need to get a new one? The tyre only been running for abt 4500km.
