You are right I went back to look at the chart and noticed I was looking at 1 over on it at the xr1200, my bad. Thanks for the correction.
Haha no problem. The XR1200 I'm pretty sure has the same pistons as the other 1200s but it has decked heads similar to the SE heads bumping it to 10:1. I'm pretty sure in the description for the SE heads it says it takes a stock 1200 to 10:1.
if you are looking for abit more go off the line, and not speed, how about a front pulley change ?.
I'm after the same thing, got a pulley 1 tooth smaller waiting to go on when I get around to it. Alot cheaper than cam change. Looked at cams, I would need to change my tuner also to raise rev limit or the cams would be pointless, so big $$$.

With your pulley change are you going to re-calibrate the speedo or just guess how fast you are going? I know you can do it with the SEPST and a dyno.
I agree with you on the price thing. I just have the fuelpak which has no control over ignition timing, so its no good when you add cams/mess with static cylinder compression (even though they will tell you it is). The cams are only $300 but then I would have to pay $450 for the SEPST and then $2-300 for the dyno time. So $1100+ for 5-10HP on the top end..I think I'll pass. But I guess I could gloat with the dyno queens at bike night that I have a Sportster with 90HP haha.
i dont know how it ran before the heads- a friend of mine bought it new and put a ton of money in upgrades then sold it to me with 1800 miles on it for what he was offered in trade. i have raced a stock 48 and pulled away from him fairly easily- coulda been the rider and not the bike tho-
thanks for all the input tho. seems like everyone i talk to (HD techs at different shops) tell me something different, i just wanted the opinion of people that may have already done this
