Thanks for the kind words, Rod. I'm not going for originality as the bike is already a real Trigger's Broom (I am thinking of naming it "Trigger" ), and it's never going to be a show winner. I must confess to choosing zinc mostly for cost reasons. A quid a bolt isn't a lot, but added up over the whole bike, that's the fork refresh paid for, or a good chunk towards the engine rebuild costs.Hi Postie.
I considered zinc plate over stainless for my rebuild but was swayed to the latter due to the corrosion free properties of stainless.
Pitting can occur with stainless, but this would require severe environments which might include the presence of corrosive chemicals such as chloride.
The problem with zinc plating is that corrosion will take place once the zinc coating is damaged.
Such damage can easily take place simply by the pressures brought upon the respective surfaces of fasteners when tightening takes place.
On the other hand, zinc plating is ideal for those who require fully original restorations in which original fasteners are valued in a rebuild.
There isn't a single part I've taken off it that isn't going to have to be reconditioned or replaced, so I'm trying to keep the budget sensible where I have the option to. In this case, given the bike is only going to be ridden for pleasure (nice days, basically), and will be cleaned carefully after use, I thought I'd take the chance on zinc.
Having run modern(ish) Jap bikes previously, I had a good lesson paying attention to fasteners, which really do not cope with British weather and road salt at all. My old Kawasaki ZZR600 used to corrode fasteners almost in front of my eyes, particularly around the forks and front brakes. Regular washing, and wiping a rag soaked in 3 in 1 over the bolt heads every so often seemed to keep the worst of it at bay, although that was ridden all year round and used for commuting occasionally, so it had a pretty hard life. I'll have time to tinker and fettle the old girl once she's running, so I'm happy to add fastener care to the list.
