I take my XB12 Lightning long to the track at Barbgallow raceway every month (Perth, Western Australia) its stock apart from being an 09 with a set of tuned headers, open airbox mod and a Drummer muffler....I've got the Pilot Power 2CT's fitted.
The circuit is reasonably short with some fast corners, i beat all of the Jap stuff in the corners, and some Ducati's, the Jap 600's can beat me on the straights, and the thou's just fly past...bottom line is most of them don't pull out of the corners as hard as me, can't go as fast in the corners, as for the straight line stuff? well 1250 barrels, stage 3 race head and cams from NRHS will come soon and these will help, progressive springs will be fitted to the front at the 10,000 mile service. Maybe I might hold them off for a bit....but at the end of the day everyone comes to look at my bike at the track days, everyone says it looks amazing, it sounds great, it has almost 90 pounds feet of torque at the back wheel, and it gives me a huge grin, I don't care if I get beat in the straights, I can compete and win in the corners, all of those Jap guys and most of the Ducatis would love my Buell....it makes me smile, and it looks beautiful, its unique, its rare and it is fast in the right hands, but it is at the ned of the day the evolution of a 1957, 2 valve, pushrod V twin motor, and like everything it has its limitations, but on balance I would not have any other bike, all I need to do is work on my corner speed, the other bikes all need a serious facelift and will alwasy look the same....
