1075 barells

[Screwriverracing]

Hi,

what barells are interchangeable with a gsx 1100 katana, barells are marked 1075,

will Efe barells fit?

Cheers SRR

You can fit 1135 EFE block if you open the top crankcase mouths a little

But remember 1135 pistons are 20mm pin.....the 998 and 1075 use 18mm pins

Thought so, crank cases have already been opened up, de-tuning it and want to put lower comp pistons in to put it back on the road, anyone have a block and pistons for sale ?

Thanks.

SRR

although if you are fitting an 1170 big bore kit to a 1075 motor, using an efe block will cut the cost of boring as youre only needing a couple of passes of the bar to open them from 1135 to 1170, just remember to use 18mm small end pistons.
