It looks as though I'll have to buy a new curly jl3 for my project as the ron moss ex box i was planning on using doesn't seem imminent.
I hate rusty pipes so I'll either buy a mild steel and get it nickel plated or go straight for stainless (not polished). It's the same end cost but a bit less hassle if I don't need to get it plated.
However, I'm sure there's a problem with stainless on 2 strokes or is it my imagination?
