Engine bolt kits

Post by FatFreddy » Thu Apr 18, 2019 10:07 am

As I don't have a garage, ride all year round, and am lazy about cleaning, my bike is showing its age a little. In particular the fasteners, many of which are showing signs of corrosion.
In the main this is a cosmetic problem but it's annoying me a little. I thought I might spray a little WD (?) or oil on em to prevent it getting worse... an oily bolt looks better than a rusty one.
But...
When I was a lad, bolt replacement kits were all the rage. A few of my mates fitted garishly coloured anodised bolts to their superdreams or RD's or whatever.
They don't seem quite as popular these days.
30 seconds on Google offered me a stainless steel set (£90+ quid!) but I was told years ago not to use stainless bolts as they are more brittle than mild steel and more likely to snap if stressed. But replacing em with mild steel would be pointless as soon enough they'd corrode too.
So, any thoughts folks?

Firstly, I'd suggest ACF50 (or similar) rather than WD40 .... WD40 is more a lubricant and water-repellant than a corrosion inhibitor. ACF50 is made for the job
Secondly...... there should be no problem replacing engine case bolts etc with stainless - more than strong/tough enough. However for safety-critical stuff such as caliper bolts, swing-arm and wheel "axles" better to stick with the genuine article (and use a corrosion inhibitor!)

Probably cheaper to buy a garage, but very pretty.

I had a DRZ with many rusty and corroded bolts, I'm too tight to buy a set so I took each one out and measured it then ordered packs of 10 from eBay for about £2 per pack. I did the whole bike and have loads of spares for less than £20

It is easier to defend yourself against a thousand enemies, than it is to defend against one backstabbing friend

Must admit, I would use high tensile steel for engine bolts, just like your 1960's Triumph or Norton used.

Set up a bench grinder with a wire brush wheel, next to the bike. Then just remove each bolt one by one, buzz it through the wheel for a nice bright shine and refit with a squirt of WD / ACF or whatever. I've revived whole bolt sets on bikes very nicely like this.

Or...buy a silver permanent maker pen and colour in the rust in situ!
