1982 GS1100EZ Welded Crank Question

[cromwell1234]

JPAUL tell us how you got the number, please???

I've seen 4 or 5 big left end 82 cranks when I worked at the dealership in the mid 80s & I KNOW at least 3 of those motors had NEVER been apart. As for the serial #s after 140000, I'm not sure. I know for SURE though that some of the LATE 82s had 83 cranks & rotors in them! Ray.

hmmmmmm,
ray would you sware to this under oath?
just kidding..

Actually, Yes I would! Ray.

If it is a winter project, send it to have it welded. I would NOT send anything to Falicon but John Pearson is good as well as Stan Gardner who does all of my crank work. I would send it to whichever is closer to you. While it's apart, have the clutch basket rebuilt & welded & put GS750 oil pump gears in it. Instead of going 1166, find an 1150 cylinder block & make a 1229. An 1100 cylinder 3 mil over is an 1166 where an 1150 cylinder the same 3 mil overbore is a 1229! It's a pretty good difference in power & the same amount of work either way. To me the cost difference in the 1150 block is WELL worth it! Ray.

Whats wrong with falicon?

I checked my motor and it's stamped "153643", so if JPaul is right , this number is above 140000, therfore it should be a welded crankshaft, can anyone firm this up--that would be great!!

I would open her up and look to see if it's welded just to be sure.

Buy a stator cover gasket & get a rotor puller for a BIG left end crank. If the puller is TOO big, you have an unwelded 82 crank. Ray.

 

[Suzuki mad]

Looking at the Suzuki workshop manual they changed the Rotor on the SZ 1100 onwards. The newer rotor is on 118mm across against 130mm and the puller is smaller on the smaller rotor.

09930-34930 puller part number.

I know as I've got one for my 1983 ESD. The one that the dealers let me borrow was too big and when the crank came out it was welded which was a bit of a suprise to me.

Mine, however, is a black engine starting GS110X-16-----

Suzuki mad

Thats a tough call on specific dates. Dig through the search "twisted crank".

Its a start....

I had a long talk not too awfully long ago with Jeff Saunders (from Z1) RE: date of manufacture discrepencies. From what I gathered from the convo, in the US, DOM vs model year of sale dates werent really regulated untill later in the 80s (84ish i seem to recall him thinking) Some models debuted as an 82 model, say, in MID 81, July-Sept area, whereas nowdays, those would have been 81 models still, and new model year bikes would not have been sold untill Novemberish of 81. Some dealerships would have sold them as 81s, and they would have been titled as 81s, but some would have sold them as 82s. This is why there is alot of confusion on certain models vs parts and parts fiches. Its also likely the reason that 82ish parts would show up on a model supposedly sold as an 81 in the dealership.

Model year designations are not regulated even today as far as I know. They aren't in the auto industry anyway. For example, I've seen certain manufacturers release a 2004 model vehicle even though the production date was 3/03.

The typical start up time for new model manufacturing is July or August of the year prior to the designation; so a 8/82 mfg vehicle would be a 1983 model year. Of course, this depends on the manufacture - there are no rules on when they must start or stop.

 

[cromwell1234]

Opened checked and rechecked the crank "IS WELDED", don't care when, who or how but thanks to who ever did it--one less thing to worry about when i'm trying to keep up with the newer bikes-----

 

[blowerbike]

i will go out on a limb here..imagine that eh?
80-82 gs1100e 16v. small taper cranks...
eveybody with me?
small taper cranks takes the large rotor puller.
83 gs1100e/es and all 1150/big taper cranks ...
still with me?
large taper cranks takes the small rotor puller.
anybody who may have said otherwise just forgot im sure.

OK lets work our way through these things one at a time, first Suzuki manufactures the following model year from July of the previous year; i.e. 7/81 on is 82 model or "Z" model designation if you like.
Welded cranks is a mis-nomer, ONLY the crank pins either side of the primary drive gear were welded (thus it can only be seen with the clutch hub removed), this was the point at which it was found the cranks "twisted"or de-indexed, this happened at or about engine number GS110X-140000 (the actual number is on the microfiche, the real fiche not the cut down versions shown on various websites) this was also the point that the taper was changed from 1 in 7 to 1 in 5 where the stator rotor is fitted, so yes the "big" crank end is a give away, BTW the journal size for the starter clutch was also changed from 31mm to 35 and an oilway was deleted as this was the point that cranks were snapping at ;also at the same time the clutch hub spacers and clutch plate arrangement was changed.

Hate to throw cold water on this therory and cause cromwell more worry but the number on my twisted crank engine is 151154.

Mine is 146884. Twisted.
