Has anyone put a 1050cc kit on their XB9S yet? and done any head work?

I have installed the 1050 kit, heads ported and polished as well as milled, Buell race ecm, Micron exhaust, race air filter. Was wondering if anyone had an idea of what power this set up was making and if you have had any fueling problems?

1050kit, redshift 585 cams, roller rockers, darkhorse crank, Micron exhaust. The baseline run was with the above hardware, but stock ECM with Techlusion module. After is with the Race ECM and Hoban Bros. mapping work.

Nice gains across the board, but the big bump in torque at 5000 rpm has me stoked, that's where it felt seriously flat before at the track. I get to ride it for the first time at Grattan next weekend. Should be fun.

Very nice. Question: Why not run it to the 7500 rpm red line? Looks like it would have hit near 90 RWHP.

I wondered about that too. They probably have a pull that goes out to 7500, we just grabbed on at random for this plot. It wouldn't have made a huge difference though, this one goes up to 7250 and we still have the soft limit calibrated at 7350. That extra 100 rpm would have given me about 1.5 hp at constant torque. I may play around with moving the soft limit out of the way at the track. Its hard to tell if the bike has run out of spit, or I'm into the soft limit on the straight. It makes it hard to tell if I have the gearing right. But you're right, 7500rpm should just push me over 90 rwhp.

Looks to me like the run shown above stopped right at 7200 rpm.
