Hi, I am restoring /tidying up my old 400 Four.
Bike is low mileage and engine runs very well.
I want to paint engine but do want to strip it down,
Engine is out of frame and sealed so was thinking
of either getting it soda blasted or vapour blasted.
Has any one painted their engine with out taking it apart
and got good results. View comments greatly appreciated.

I will be interested in any info on this to

Me too :D

Hi Guys,
I did my engine without taking apart all I took off to paint individually was the breather cover on top of the engine and the sprocket cover,
I Gunked my engine to get the worst of the grime off which worked very well

After that I gave it a good clean to remove the gunk residue then got to work with my Dremmel I ordered various dremmel bits but found the small wire brushes the best to get in between the fins in all it took me over a week just to prepare the engine for painting,
I made sure the engine was spotless before painting for paint I used Simonez paint spray which doesn't need primer or baking I masked off the finned part splines etc then did the silver first I gave it 4 coats with at least a day in between, this is how it turned out,

I saw a similar thread on the US site. In most cases I believe the paint has to be cured by heat. I discovered this to my cost when I did my 400Four (although I had the engine apart to paint it) and one of the carbs leaked on the top crankcase). Anyway, the American chap made an oven to cure his entire engine out of a large, baking-foil-lined box which he heated to about 90C or so with a hot air gun. He had some sort of thermometer in the top plus a removable flap to let heat out so that he could regulate the temperature. It looked a good idea and one I am toying with while the more meticulous part of me is urging a total engine strip and inspection. Hope this helps,
Paul.

Worth looking at Stove Enamelling, I had my F2 satin black engine done, it's thin so no overheat problem fuel and oil resistant better than any other engine paint I have seen(http://img.tapatalk.com/d/13/12/05/sequby6e.jpg)
