I apologize, Im sure this has been asked and answered before but approximately what is the build date on the 82 GS1100EZs that they started welding the cranks ? Im not having much luck finding it in the search outside of the latter half of 1982
 
in my career i have never seen a factory welded crank in a silver engine.
i wouldn't put faith in certain engine number range.
the way i have seen it for over 20 years is...
silver engine=non welded small taper.
black engine= welded large taper.
bottom line is pull the clutch cover and have a look..

Ray claims there were some unmolested welded crank silver motors. He would have to say how many he has seen. Not many for sure.

hmmm...
so the stator cover is easier to pull than the clutch cover?
is that your point?
:-\\\

yes ray has seen these but i refuse to go by engine batch numbers...
smoke and mirror's folks...
black is good..
silver is bad..

GREAT! So my '82 is welded. And all it took was a can of high temperature engine enamel. :)

Seriously, I'm stock except for pods, pipes and jetting, and have been to redline numerous times. Is there much likelihood that after 25,000 miles my crank will twist (if that's the proper term)?

Of course I understand that if I go big bore, hot cams etc., I increase the risk.
 
I would start worrying about the clutch basket grenading. More than the little end of the crank can twist off or the crank twisting. If you chop the throttle at high rpm's it can twist. But the stock clutch baskets are famous for coming apart.
Big end cranks " 83 and up" are welded in a couple of spots but not good enough. If you build your motor it will need to be welded up properly.

That is ridiculous, black doesn't mean a welded crank, :(


it means faster.........:rolleyes:
 
I worked at a Suzuki dealership & have seen at least 10-12 82s that had welded small end cranks. I've also seen 3 82 motors that had never been split that had large left end cranks in them. As far as what #s got them I have no idea as I never recorded #s that long ago. I also saw several 82 Katana 1000s with 81 heads on them with 20 bolt valve covers instead of the 24 bolt. If you are building ANY kind of HP, get the crank done correctly & have a good clutch hub built. Those 2 are MINIMUM for building an engine that will live!

Mine twisted in 82 with about 3k miles on it. Rebuilt under warranty by a very small NC Suzuki shop. What do you think they used as a replacement crank ?

i doubt that but i'm not sure.
is it welded?
maybe they sent it to falicon..i don't know?


added:
if you have 2 bearings that the SC gear ride on then it is 100% a small taper crank.
