1166, 1197, or 1260 for my gs1100e?

[pano]

I am getting closer to boring out my project bike 1100e block. I had some discussions this weekend at moosehead. I was originally going to go 1166/68 which changed to 1197. Now I am considering 1260, all 10.5:1 compression.

I want it streetable and plan to run gsxr36mm flatslide carbs, stock 1150 cams, high vol oil pump gears, oil cooler, and topend oiler. It will have a ported 1150 head as well. The head came of a well tuned 1229 (1150) with 38mm rs fatslides. It won't be a track bike except perhaps on a rare occasion with the GSR gang.

I guess i am concerned with throttle response and overheating. I have been assured that with mild cams and the gsxr carbs tuned on the rich side I will have good mid range and no overheating issues unless I get stuck in bad traffic. Your thoughts.

I ran a stock block 1198 in the early 80's but it was a dragbike only.
I have a 1166 kit in my wifes (-: street bike with an 1150 head that I street ported and have had 36mm GSXR carbs and now 36mm Mikuni flatslides and it runs good and no heating problems but I don't get stuck in traffic very often because I am mostly outrunning the traffic (-:. With the 1198 or 1260 you will have to use an 1150 block. I am completing my 1327 Turbo bike that I have an APE big block on and I am going to run it on the street but I don't know how warm it will run just yet, may have to ride it in the winter only.
