Hey thanks for the reply!
I was in the B group at the trackday but when we lined up after lunch i was running late to get to the grid and ended up lining up at the end of the group with the slower guys. The whole morning i was in the front group. Anyway, we get to the last turn coming onto the straight and the guy is front was almost crusing...i tried to avoid him in time but couldn't. The front locked up on the brakes so i let off the brakes immediately but then i was already going into the right side of him. He had his passenger pegs still on the bike and that's why clipped my left leg and i went into him.
Basically it was my fault. i didn't realize there would be such a huge difference in speed between the back and the front of the B group. I should have just pulled into hot pit and pulled back out when there was clear track. I also think my throttle was getting a little stuck and needed lube so that could have been part of it.
Anway, i learned a lot from it and will not repeat the same mistake.
