4V or 8V TSCC?

[KGB]

I'm a little confused here

The factory sticker says GS1000S--1982 Katana, not a Wes Cooley
It has the square end caps and TSCC on the engine covers.
Is this a 2V or 16 total valve motor?

2V as in 1 intake and 1 exhaust

My 1980 GS1000 motor has round end caps and is a 2V motor?

Katanas got the S designation rather than the E. The Z means it's an '82.

Square end caps and TSCC, it is a 16 valve engine. (Screw adjusters, not bucket and shim)

I wasn't sure if a 1000 came with the TSCC or just the 1100 family.

Earl,
That's what I thought.

Billy, Thanks also.














or maybe I need to read these when I'm sober...........

The 82 Katana is the only 4 valve GS1000 to my knowledge. The engine is actually a 1100 4 valve, factory sleeved down to 1000 for AMA rules at the time (unless I'm mistaken).

The cam end cover are always a dead giveaway.

You are correct.

It was a 1000 to make it AMA legal for Superbike

Joe Nardy has taught me a few things, just needed to pay attention to the Old dude

Basically a 8 valve engine have spark plugs that protrude out and 16 valve ones sit upright.
