    Ah, the old "urgent gardening" ploy... yes, it's paramount to get those flower beds in order for the spring season!

    Hi all! Yes I'm still here. Garage has been 're-arranged', multiple parts have been sourced and bought (£950 and counting, not including the £400 two-into-two with balance box exhaust system I bought earlier. Eek! Don't tell the Mrs!) It does include a £160 front fender that is a direct copy of the Honda original from David Silver, not that ugly 'fit several bikes' thing that I fitted to the 200. I thought I'd splash out . . . . . . .

    Swingarm, centrestand, centre rear fender, electric board, headlamp ears have now all been painted. Pictures not taken yet but will follow soon I hope. I want to get the front forks rebuilt and on the bike so I can re-fit the engine using the rear engine bolts then attach the centrestand and use this to lever the engine up in the air, then temporarily re-fit the front wheel. Then I can drain the engine oil and set to work removing the aluminium oxide plastered all over the engine.

    That's the plan, anyway . . . . . . . . .

    Monsoon season in the UK at the moment, no gardening or biking for me.

    Still, at least I don't have to get the hose for watering the plants, like I had to do a couple of weeks ago.

    As Richard says, Monsoon season over here means no garden duties for me either at the moment. However, escort duty for shopping trips up town is on the cards unless I can disappear into the garage and lock the door . . . . . . . . !

    Vintage leather jacket turned up by post today. That took some explaining too . . . . . . .

    Ultrasonic cleaner turned up yesterday, along with a litre of fork oil and some various springs and things. I think I have most bits now.

    Except tyres, a battery and some Por 15 for the tank. Will the spending ever end I wonder? I need to get bolting stuff back on.

    Next up is an attempt at zinc-plating the chain adjusters . . . . . .

    I've been wire brushing innumerable parts and dropping them in Por15, well, my version of it, 96% phosphoric acid as gardeners use to alter the ph balance of soil, mixed to 14% acid with about 2 litres of water, then giving the parts a quick waft with a nylon wire brush on a drill. Sometimes they just cleaned up exceptionally bright, other times they looked as though I'd plated them! Can't understand this, my rear pins in the cush drive that hold the wheel on are shining like chrome! Sometimes lots of bubbles come off the part in the Por15 substitute so it must be etching the parts slightly. Whatever, parts are half done now.

    Must take some pictures soon as this thread is getting devoid of them. You like pictures . . . . . . . .

    During a moment of madness I loosened all the bolts and screws on my carbs in readiness for separating them so I can remove all the jets and rubber pieces then clean the outside of the bodies before I dunk them one at a time into my new 3L ultrasonic cleaner. I realised before I'd gone too far to take A LOT of macro photos of the linkages etc so just in time I saved myself from failure. For now I'm soaking up Longdistancerider's brilliant post on how to clean the darn things so they work. Hopefully I'll photo it as I go.

    I've been trying out lots of different zinc plating concoctions and after a lot of faffing I finally plated my gearchange lever and linkage. Pure zinc pieces, epsom salt, vinegar and a phone charger and I was plating!

    Before and after

    It's not perfect. I could have spent more time filing and sanding away the rust spots before plating but I took so much metal away I think I'll leave it for now. I may run the bath again for a bit more coating and a smoother, deeper finish but for now it's a hell of a lot better than it was!
    I've sorted more bits to plate and bits to paint but holidays loom on the horizon so yet again I will be forced out of the garage. I WILL get to post more pictures.
    Just not yet . . . . . . . . .

    That looks really good James, could you please post details and photos of your setup?

    Yes, I'd be fascinated to see details of this process as well. I have a set of spokes that would benefit from plating.

    Would it work on rusted chromed parts ?
