Engine cleaner/restorer.

Hello again! Laughing

The previous owner of my Cg125 had the accident and then stored it away without cleaning the engine. It has now corroded and looks really quite tatty, is there anything I can put on to restore it?

There are also a few really rusty bolts, where would be the best place to find some replacements?

Thanks

Tim.

Hi,
not sure how far you want to take it, but a wire brush & black ht paint is a good start.
or if your stripping it down, bead blasting & polishing?re-plating?
various options.depends how far you want to take it & how much you want to spent.
as for nuts & bolts, dont bother with oem stuff, just take the old ones into your local hardware shop & buy like for like.
or you could do what i did & spend about 50 quid! but for that i got nuts & bolts of almost every size you need, with washers,spring washers,nuts,nyloc nuts etc.
hardly needed to buy a nut or bolt yet. (any that are too long , i just cut to size with boltcutters or dremel)
cheers,
GAZ

Apologies for hijacking, but I have a similar problem.

I was thinking about rubbing down the engine casings with various grades of wet and dry paper then coating the engine with ACF 50 until the spring when I'll re-paint it.

Anyone got any opinions on this?

Also, the down pipes on my exhaust are slightly rusted (only surface, no deep corrosion), is it possible to polish these and again treat with ACF50 - if I use a polish, is it likely to cause a problem when the pipe heats up?

My CG has been sat out in the rain for a few years - actively used and maintained throughout though, but the engine's aesthetics degraded... The non-painted metal part (cylinder/head) got really bad looking, with salty-like deposits all over it.

A few weeks ago I took a wire brush to it and all of the "salt" (I say that as I don't really know what it is, but it looks like salt) literally brushed off like powder. I had to rewash the bike as it had all settled on the front wheel!

It's not easy to shift but it goes with wire wool/wire brush. Looks much better now.

Way to make me feel stupid :lol

But yes, the aluminium oxide comes off easily enough with a wire brush. Very Happy

You could have it wet-blasted (like shot blasting but using water instead of air as a carrier). There's always the risk of getting the media in the engine though.
