1260cc in an 1100 block.

[Guest]

Can bore out my 1100 block to 1260 and use the 1260 cylinders with out a overheating problem. Or do I need to put different sleaves into my 1100 block to make it work right. I plan on using this set up on the street so I would like to not have overheating problems.

The 1100 & 1150 blocks are only able to go 3mm over bore. The 1100 block can be an 1166 & the 1150 can be a 1230. To go bigger than that will require sleeves. I build 1400 street motors & have no problem with cooling but there ARE things you HAVE to do. Call me at 714-356-7845 if you have questions or want to build something! I build & race big GS engines & know how to make them live. Ray.

re-sleave or BB only.
if you really want a 1260 i may have a couple used(finished kits) available for 18mm pin stuff.
you have to split and bore your upper case for bigger liners also.

You can sleeve your 1100 block for 1260 and not have over heating issues. That used to be a very popular mod and we still offer it. We had a customer with this kit and 370 cams, ride the bike from California to New Orleans and back.
