Stainless bolts in Aluminium threads ?

[Benni]

Hello 2wheelerz,

since changing the chinese bolts in my small engine to V4A I am in doubt about the chemical corrosion that might happen.

I mount these bolts with anti-seize paste (not copper grease) to prevent the threads crumbling into white dust.

What are your experiences and opinions about that, other than "get some proper Titanium bolts" ?

You'll be fine with the paste applied.

Triumph build their new bikes with stainless into ally, dry. I've seen some corrosion on year old fastenings but nothing too bad. I will always put paste on when reassembling.

Ti will also have similar chemical corrosion against alum... you will be fine with anti-seize / copper grease or use a waterproof threadlock.

Nothing wrong with copper grease under these circumstances. I have plenty of stainless bolts in alloy with copper grease applied and have never had a problem.

Fastners on bikes that are often prone to seizing can be made much easier to remove simply by just loosening them maybe once a year,regreasing and retourqing them

I will have no problem then, as it is a chinese engine it WILL be neccessary to open it up every two weeks...8-)
