I almost crushed a guys melon Friday 5/23/08. Wear a helmet. Wear a helmet. This guy should have had his brains all over my bike but i guess the angle was just right i threw him a couple yards from his quad instead of crushing his body. The guy thought it would be a good idea to use a dune flag but not a helmet?? . There was no way i could have seen that flag the dune was like this: / \ ... As i came over the peak i was air born and couldnt do anything about it. This guy was on my landing strip and if he had not been drinking he could have gassed it and got out of the way. I hit him in his face, smacked his safety sun glasses off, and knocked his shoe off and sent him flying off his quad. I guess that was better than crushing the guy. I luckily just rolled in some sand and got up, ribs still hurt. My bike also hit his bars breaking them along with my radiator and front brake disc. SO! I need a Left Radiator for a 06 yz450f and i dont have a lot to spend. I can find one for $270 online but i wanted to ask you guys if anyone could hook me up if they already had one that you could sell me. Or if anyone knows a cheaper place to get one, thanks! Also the 07 wavy brake disc is cheaper than a 06 brake disc. Anyone know if that would fit my 06 bike? Thanks again!
