Black painted engine covers

After the time, I got bored of my brushed finish engine covers. They look not bad after recently polished, but fastly degrade due to dirt and scales, and I felt like they needed less time to return to "spotted gray" finish than me to set them shine again.

I was thinking some time about buying the chrome version of covers. They are not serial mounted by any speedy model, but available due to some T series using them.

I also liked the black finish used in some bobber and T models, and saw one with such black covers, and then someone suggested me an option: paint the original covers with powder paint threatment. The same kind of threatment original engine pieces get in manufacture.

I asked a firm working on that - they mostly paint stuff like doors, window grates and such, but confirmed they had no problem on painting that, and price was very interesting, hugely cheaper than new covers.

This is the final result, adding also chrome alternate decorative badges:

I love the result. I think giving extra contrast making the bike look like "stronger".

The harder part of process is taking out engine covers, mostly for the right side alternator area involving unmounting all the end transmision area and exhaust to release the alternator cable. But simply a matter of time.

After full unmounting the covers you only have to degrease+clean thoroughly, and cover the sensible areas with masking tape, like the border mounting surfaces, and the bolt, rod, stator link and dowel areas:

It is important the masking tape to be heat resistant, as the paint process includes placing the painted piece in a 250 degrees oven. Also there are a few rubber oil seals important to take out and keep (or replace if old).

This is the final result of the clutch cover with the chrome badge placed, still with the mask protection visible. The finish is named textured black:

Including the paint and the different gaskets cost was under €100.

Nice job, textured finish looks spot on, probably better quality than the Triumph black cases as well, seen quite a few of those with corrosion and paint bubbling from the machined faces, probably not in Spain though:cool:

I never heared personally about such fails in crankcase covers. I know about a guy who is fighting now to get warranty because suffering it in the engine carter block (much worse situation i think).

The people who made it have a many years long experience with pieces intended to be 24/7 suffering weather effects like gates and windows and they last, thus i am sure about the endurance of the finish.

I was looking for that as i use the bike daily in every condition - not a sparse weekend strolls show off bike.

I also love the contrast with the silver bolt heads.

Was very lucky as a guy not far bought a used unit with chrome badges, but he prefered the originals (they were over the brushed metal covers, where they do not stand out so contrasted), so I got these cheap :)
