KATANA 1000 crankshaft - welded?

[petetherod2002]

Can anyone let me know if Suzuki welded the crankshaft on the Katana 1000.
Thanks Pete

no they didn't. not on a standard road engine

Many were welded by PO's after a spun crank to ensure it didn't happen again. Welcome to the fourm!

As above
not welded as stock but its a common thing to find

i believe the 1000 crank was lighter than the 1100 in stock form though, they certainly spin up a lot faster

I was thinking the rotor was lighter, not the crank.

Not sure on the 1000 models but yes, Suzuki had a welded crankshaft for some 1100S models, there was one in stock at Suzuki Australia in Sydney NSW in 1995 and is not an aftermarket item. I have tried to find the part number for this in my scattered files, not really files just piles of papers and receipts that live in boxes and drawers and various places in the shed. Cheers.

This is correct. The 1000 had a smaller diameter rotor to lighten up the crank rotating weight. The stator was a smaller diameter also. Ray.

Welded crank

Well thanks guys - I now know I shall have to pull the Kat apart to get it done, racing the beast in a Classic Production Class in the UK next year, but also keeping it in road legal trim.

Here's another one for you - been told that if you use a GSX750 exhaust cam in the Kat 1000 it gives much better performance - anyone else heard of this?

Great forum - Pete
