Bolt/metal questions...

[pjmcburney]

I recently picked up an RG500 that's seen (much) better days, as one of my new projects.
There's a LOT of work required, the PO's have done a good job at making my job bloody difficult!

It really is a basket-case, just basically a rolling-chassis and an engine (well mainly an engine) in boxes.

My question is, I'm missing the majority of the engine bolts including the one's that hold the various major parts of the case together, what pitfalls will I come across if I use stainless bolts with the aluminium - will I have to use anti-seize or anti-gall in the assembly process?

I intend using socket-head stainless bolts everywhere (except the large engine support bolts) on the bike, as it's a cheaper and better choice aesthetically and corrosion-wise, but it's the ones on/in the motor I'm most worried about.


Any info greatly appreciated
Thanks

I've never heard of an issue with galvanic corrosion between aluminum and stainless. I would not expect it to be any worse than aluminum-steel junctions. You can use anti-seize on the threads if you wish, but I really do not think it is necessary. I did exactly this on my engine, and replaced every fastener with a socket head stainless steel one. No issues, but then I've not tried to tear it down since then.

14 years and running on my GS1000. Never used anti-sieze. No issues. Bolts come right out

The only problem with stainless is if its torqued to itself. So if you have any S/S bolts and nuts together such as on main engine bolts, you should use anti seize on them to prevent them galling.
