Katana engine

[thexman2008]

Hi all,

I was wondering if there is a differance between the engine from a GSX 1100 with the rectangle headlight and from the Katana 1100?

is there a site where you can check what engine it is based on the engine number?

Regards .... Tom

The engines are pretty much the same. The Katana had a smaller slighter flywheel than the 1100 ET and it took the rev counter feed from the coils where the 1100ET used a mechanical drive from the cams. Some differences in the rocker cover too on the earliest ET engines. You can take out the worm drive on  the rocker cover and plug it. The Engines are otherwise identical. Both were GS110X from memory.

When you say con rods, do you mean small end ? i.e 18mm gudgeon pin or 20mm gudgeon pin. If there is another difference its one I havent happened across and I believe the pin size was a variation between 1075cc engines and 1135cc engines

[KATANAMANGLER]

The 1000cc Kat was produced for racing and had the lighter stronger con rods. The 1100kat and the 1100ET shared the same con rods.

1135 and 1075 engines have different primary drive gearing too.

Same dimensions as the 1074/75 cc GSX engines, but a different forging number on the rod itself - allegedly a beefier rod.

There's apparently the 492, the 492 with oil splash dimples and the 493 (which is the "Katana" rod i believe).

There's also this thread:

492s hang together just fine for most purposes, they make great bottle openers too.

493 is "the rod"

Thought the Kat , ES engine made 10 more hp ?

Yes the Kat 1100 basically became the std spec for the later EZ, ES, ESD, etc.......

@homerSo what’s the three ‘pips’ and the 2 for?

There is a supplement in the back of both 750 and 1100 workshop manuals covering all the changes from the standard GSX.

Everything from anti-dive, engine, bodywork and cable routing and service specifications.

Here are a few pages.

I am not a expert but major deferance is flywheel, flywheel cover, carburator jetting, cooling fins on the head and crank where the flywheel fits
