Front Sprocket nut dimentions

[Guest]

Hello fellow GSer
85 GS 400E
Following a series of unfortunate events I lost my front sprocket nut (new sprockets and chain but the nut must have rattled off)
I ordered a new one right away (0914020009 - Canadasmotorcycle express shipping) but I really need to be able to ride on Wednesday (a beautiful girl is involved).

My question to you is: Can I temporarily substitute a hardware store nut untill my new OEM part arrives? If so does anyone have the specs, I measured 18mm outside diameter of the countershaft but just wanted to be sure, also not sure of thread pitch

Any help if greatly appreciated!

I don't have the specs, but the odds of your finding a nut with the right diameter and thread pitch in a hardware store are pretty much nil.

If there's a motorcycle salvage yard in your area you might check with them. It's possible that a GS500 part will fit, those would be more common.

To be honest, if that girl is all that special then she'll understand the delay while the new part comes in. Wait for the part.

Thanks for the insight Rich, and cowboyup you're definitely right. I found an M20 nut fine thread works fine, ill try it out but I don't trust it much, the stock nut is on its way

It won't be recessed in back to make room for the splines. Watch out.
