Engine needs painting

[yoyo]

While my 2016 bike was under warranty I needed to have the engine painted, the paint looked really thin and easily came off when an air line was used to dry the bike.

The dealer painted the engine and it looked ok but 2yrs later it now looks like the pic attached (1 with flash and it 1 without) I know it's well out of warranty and it's down to me but does anyone know the paint code by any chance?

Has anyone sprayed the engine in place before? Not sure whether to brush it on or spray it.

I also thought I'd been one for using plenty of ACF50 but looking at some of those fasteners I don't think I've done enough!

Perhaps talk to some engine re-builder shops? They normally hot tank clean engines prior to painting. Probably disassembled first, but they may have suggestions.

Look up "the really random" channel on YouTube. He's a Scottish lad who restores motorbikes and tools etc. He's good at painting stuff but he generally strips things down first, but it may give you some useful pointers.

It's environmental. Your spokes prolly look like crap too.

Some parts just aren't supposed to be clean and pretty.

Given the marine climate around you & the winter weather, I would just wash it down thoroughly let the cases dry & they spray with ACF50.

Then, come spring get something like this ............. https://www.frost.co.uk/high-temp-satin-black-barrel-paint-aerosol/?gclid=Cj0KCQiAkKnyBRDwARIsALtxe7gMYS8xkH_dibqrmiwpP2l5egN0fMf52OUSia11miTA4JyPKjtA9iYaAvT6EALw_wcB
Degrease & steam clean the affected area, scraping away any residual corrosion. Then mask up where appropriate & spray carefully the cases in line with the instructions on the can. The art of a good finish is always in the prep.

Sadly, given the background, I suspect you will be revisiting the issue again in a few years, but it can be kept at bay with ACF50. BTW, do watch the corrosion on that coolant pipe too.

thats what i did with mine, the coolant pipe i cleaned and every year with a brush i paint it with black high temp paint engine doesn,t look bad i have seen some shockin ones 3-4 yrs newer than mine to

With the salt in the air and on the roads there's no real way to win this battle. Clean as much as you can mechanically with a something like Scotchbrite, use a dilute phosphate cleaner like Alumiprep (you can make your own with hardware store supplies), then just overpaint as best possible with a gloss enamel or epoxy.

Plan to do more every year.

Thanks for the help all. I'm a RoSPA tutor and have an assessment on Sunday plus the BikeSafe season is due to start, I think I'll leave it for now and will have another look at it in the summer.

I am with the leave it alone crowd.

Getting something to last will be a major PITA. The only hope you have of making something last would be to blast to bare metal which is really hard to do with the parts assembled. If you do eventually paint, you will want to get to a bare, active surface. You can get there chemically but blast to a 10 micron profile will yield the best results. Since it is a marine environment, coat with a 2 component epoxy to 25-75 microns. You can leave that as is or top coat with a 2 component urethane to a total thickness of 75-125 microns. As an FYI, if you top coat, you will meet the top end performance for ISO 12944 C5M. It does not get better

I think you understand why I am with the "leave it alone" crowd. I would rather ride
