Swiss Toni Posted September 13, 2017 Share Posted September 13, 2017 Std. Kat 1000cc barrels. How big can I go capacity wise ? Or, is it possible to remove liners, fit 1127 ones, and re-bore to fit Gen1 Hyabusa pistons? Quote Link to comment
Cheeky4648 Posted September 13, 2017 Share Posted September 13, 2017 (edited) Think the 1000 block may window out with 1127 liners. I do know you can do the busa piston gsxr liner swap into an efe block as I did one a while back. You could put 1150 efe liners in the 1000 block they won't window out.

Swiss Toni Posted September 13, 2017 Author Share Posted September 13, 2017 That's interesting. I may know where a set of 1150 barrels are hiding. Quote Link to comment
Cheeky4648 Posted September 14, 2017 Share Posted September 14, 2017 (edited) If you do the 1370 busa pistons in stock block do all your deck height checks and then machine the block before you put the 1127 liners in ( think it's 75thou or 1.9mm from memory) keeps the top lip nice and thick also liner stays as long as possible. I got a cometic fiber head gasket from them much better than copper for the road. Edited September 14, 2017 by Cheeky4648 1 Quote Link to comment

The 18mm 2nd gen slugs need somewhere around 3mm off the block. Quote Link to comment
Cheeky4648 Posted September 14, 2017 Share Posted September 14, 2017 Guessing Toni is using mk1 busa 20 mm pin as said in his post with 1150 rods. Havnt messed with the gen 2 stuff. All info is good when looking for cheaper ways to big bore 1 Quote Link to comment
Swiss Toni Posted September 14, 2017 Author Share Posted September 14, 2017 (edited) Got nothing yet, pistonwise, Cheeky. Just testing the water before I jump in buying stuff. I'd be using the stock 1100 ET rods, not the 1150's, although I might have to go with the Gen2 Busa pistons, to suit the 18mm ET rods. Forgot about that! There's a guy in last months PSB with a nice ET that's been bored to 1260! On here, by any chance? Edited September 14, 2017 by Swiss Toni Speeling! 1 Quote Link to comment
Cheeky4648 Posted September 14, 2017 Share Posted September 14, 2017 (edited) If you are keeping the 1100 rods then gen 2 busa it is. You can do a 1260 in a stock 1150 block but it leaves the liner reeeeely thin plus trying to get a set of 1260 pistons with 18mm pins may be hard to do, mtc list them but thin liner on road bike 77mm 1230 pistons are available and will bore into an 1150 block no prob. Edited September 14, 2017 by Cheeky4648 Damn phone!! 1 Quote Link to comment
