I've got a two part question. First off i have bolts and other bits that have rust on them. Is it worth it to try and clean it off and coat them with a film fluid or just go get new bolts?

Second, i've noticed that newer bikes have a tendancy to rust and corrode more severly than older bikes. My 94 cbr900 had 79k when i sold it and not a spec of rust anywhere. The following bike, 01 929 which was only two yrs old with 8k looked as if it had seen an ontario winter. My current 02 gix750 isn't as bad except for some bolts and bits.

A mechanic told me that the older bikes received some sort of coating from the factory to prevent rust and because of weight concerns they stopped applying this coating. Is there any validity to this statement?

Depends on the bike I guess. They probably figure that today's sportbikes won't last long enough before being written off to require a coating.... :D

Cleaning off rust is usually a short term deal since it'll require constant waxing or oiling from there on to keep it clean. MOst fasteners are plated with a flash of zinc to keep them shiney. When that comes off then the underlying steel rusts quick if not constantly cared for.

"Dress" screws for special purposes are often painted or more heavily plated. Because of that they should last longer.

Try cleaning it up and coating it with a light grease or some of the plastic and rubber restorer muck. THe second one doesn't stay oilly but it seems to work well for quite a while.

But if you ride in the rain a lot then new parts or paint the old ones.
been a while since i've seen aluminum and the like rust. besides the bolts, what is rusting? the exhaust headers? it will happen regardless. heated steel tends to do that.
Yeah, the outside pipes of the header have some pretty rusted out bolts up at the flange, banjo bolts and things like that. A buddy has a 02 gix 600 and his bike is spotless. I haven't ridden mine in the rain(previous owner did a handful of times)so i'll prob take the stocks ones, clean em and put em back.
I just like my bike to have a clean look.
Keeping the moisture off during storage is huge. Wax, grease, light oil is a must if you don't have a heated space.
Clean them up and see how it goes. Pacific fasteners in Burnaby would have pretty much anything you could need as far as S.Steal. Remember Aluminum and steel in contact can cause corrosion.

i tried to explain that to someone else on this board a week or so ago and they didn't seem to believe me!! kept on about salt.
not corrosion....electrolysis............
Yeah, alloy and steel in contact is more of an electrochemical deal but it still spells MESS when it's all said and done.

A few years back when steel bicycle frames and alloy seat posts were far more common it was a MUST to grease up the seat post and inside of the seat tube before inserting the post just to avoid this. And even then I needed to re do it about once a year to ensure the grease didn't wash away in the winter rains and start up the "battery" again.

But aluminium does "rust" but it's seen as a whitish bloom of aluminium oxide.
corrosion..electrolysis...either way you say it it's white and shitty!!
not corrosion....electrolysis............
All right... Galvanic Corrosion: Occasionally, Trail-et’s unique design of using several primary materials to form a composite material product is criticized for being subject to a defect called "electrolysis". What is being referred to is the electrochemical action that takes place when two dissimilar metals are placed in contact with each other and an electrolyte (a solution like seawater) is introduced. The correct term for this phenomenon is not electrolysis, but galvanic corrosion.
cool. so i was right!!
I stand corrected.........again............
That's too bad aftermarket bolts are so bloody expensive cause they look great. Something like 58$us for 4 caliper bolts. I know they're titanium but that's still a bit steep.

In some circles some contaminates in H20 would be considered "salts" such as calcium and magnesium. As long as it can conduct electricity it will cause damage to dissimilar metals

As far as the Titanium bolts go they are not worth the cash for everyday use. The word 'Titanium' is such a catch word right now. You see it every where from basket ball back stops to razors. I use the odd bit but I work with the stuff everyday and at no cost to me.
i wouldn't be too concerned about the corrosion. you change brake pads and tires and stuff so when they are off just give a little polish or cleaning and a light coat of white lithium greese and its all good.
