Bike is 03' started at 790. Went to 904. I like the 994 kit and don't have a cost thing. I guess I would just look at what I was going to do it for. All out speed power ,torque? Mine is fast enough now on the straight line and more than I can lay it over so far with out getting nuts on this style bike. Now, Thruxton? I will buy one this year and have him go as big he is doing at the time. 1140cc on a Thruxton sounds like something I need! Definitely going for the two horse stall.
