Paul - thanks very much - I've just turned 70 - must be it - thanks for taking the time to explain.
Regards - Ray.

No, I don't think the key would stick out far enough to go through that slot in the washer. It's a pretty big slot too, much bigger than the key. I don't know what it's for, maybe visual inspection to make sure the key is engaged into the gear slot OK?

Also works well when the clutch housing is all assembled and you still need to put that key in.

Who's got a clean pic of rotor wire assembly for a '75? Can't find anything on threads.

 

[Jim]

Not sure what you're asking for?

 

[Shipper]

Just a simple pic of the assembled wiring on the stotor. Didn't pay attention on breakdown and looking for how the brush brackets assemble to the holder. It looks like the copper wire bends around the bracket, no?

[Jim]

Yes, it bends around. And there's a notch in the holder for the wire to tuck under.

 

[Shipper]

Terrific. Thanks guys.

 

[Shipper]

While we're at it, is it particularly abnormal for a slightly rough track on the rotor?

 

[jpdevol]

Might be a couple of the brush holder screws protruding through the stator housing too far..

Yup... looks like a screws bein' misplaced damage.

 

[Shipper]

Its not particularly prominent. Should be good, no?

 

[Jim]

Yeah... it's outside where the brush runs. It'll still work fine. Did you make sure the screws are back where they're supposed to be?

 

[Shipper]

Did, Thanks Jim. Its looking like the PO was in here more than anticipated. Makes it soooo much more interesting.

Moving right along. Took my cylinders to get blasted clean today. As I bought this bike with everything above the bottom end in pieces, (cylinders missing and since replaced) who can tell me the standard numbers for cylinder/pistons on a stock 1975650xs. The cylinders I have read 010.

 

[jpdevol]

75.010mm on the cylinders when new.

 

[Shipper]

So am I good for standard pistons with the 010 cylinders purchased? I assume it states cylinder bore size 75.010 with the 75 not shown.

 

[jpdevol]

You need to measure (or have measured) the liners as they exist now and account for any wear patterns or scoring to determine if std. bore pistons will be in-spec. The std bore pistons will have some variance as well.

Thanks jp. Would you recommend honing the cylinders first for an accurate measurement?
