Just returned to the zed fold after 10 years in the wilderness.
Last bike (Z1B) had natural engine finish, this bike Z900-A4 has silver painted finish. Is the correct or should in be natural alloy.
Also bike has not been used properly for a couple of years and smokes like a trooper. Having read about other peoples smoking engines, could a good run sort mine out do you think?

I'd remove the sump and clean the oil strainer gauze or even fit a new one,then remove the plugs and spray some Duck Oil into the bores which hopefully will free up the rings a little??
Obviously check that the engine breather is clear,then fit a new oil filter and some fresh oil,plugs,etc and get out for a good long run on it and see what happens.

Maxico, the Z1B and the Z900 A4 had a similar finish. If the Z900 has a distinctly better finish it could have been aqua-blasted which is similar to the "Smelthust" finish which is carried out in UK. I don't think anyone would spray it silver and expect it to have any long life, Unless its a NEW process?

Someone has sprayed it Silver. Some of it is chipped, some has bubbled up a bit, and you can scrape it off with a blade.
Am I correct in thinking it should not be on the barrels and engine casings and that I should get it cleaned off?
