Katana crankshaft / rods

[no class]

Heard somewhere that the Kat 1100 cranks/rods differ from the gs 1100 ..... can someone shed some light on this ?

[Gixer1460]

The Kat rods are marked '493' and generally regarded as stronger than regular GSX rods - don't know the difference but racers try to use the 493 rods where they can.

I have a few stator  and covers from gs1100 80' - 81' and upon inspection it appears the Kat has a smaller stator ???

Yes some Kats have a smaller stator....I thought it was just the 1000.

Yes, the Kat has smaller stator diameter than other GS1100s. I'm not sure if the Kat has both small and big taper versions as well. At least small taper has been used but I don't know if it was changed to big taper on 83' model like on other GSs.

curious to see if the stock crank was partially welded from the factory as some of the articles I have found on the net dictate ......

[Arttu]

They started weld cranks on late 82'. So all black engines should have welded cranks and silver ones non-welded.

Here's an old pic to illustrate the beefier Katana rods.
