GS750B engine options

[GS750]

I am currently about to restore my GS750B engine as it is starting to get a little low in compression, and I was considering my options in regards to the finished product and the look it will have.

I have been scouring the net and magazines for pictures of the original bikes so that I can see the way the engine was finished off (paint etc)

I really would like to see how the engine looked originally so that I can make a decision as to whether or not I will keep it original or going for a different look, so my question is can anyone please send me some links or pics of the original engine finish?

Also does having a black engine really reduce the engine temperature by much?

I am sorta between a few styles, I like the really clean look of a silver engine, but I have also sort of been thinking of doing something along the lines of:

satin black engine,

wrinkle finished barrels and head (with file finished cooling fin ends),

polished engine parts like:
clutch cover,
points cover,
stator cover,
drive sproket cover,
clutch release cover,

and also maybe chroming the starter motor cover.

Well in theory it should... but I haven't seen any actual figures quoted anywhere, so in the end it may only be a marginal improvement, for all we know.

The downside of a painted engine is that unless you have your head, cylinder block and cases clean of ALL traces of oil etc., your paint will start to peel off in patches before too long, and just end up looking plain crappy.

A 'wrinkle' finish might look fine for a short while, but it will catch the dust and road grime like nothing else, and be hard to keep clean.

As to what your engine should look like for your bike, have you been to www.suzukicycles.org and scoured the relevant pages for your bike there?

Here are some great pics of a '78 C model. http://www.ronh.org/suz750e_78.htm Other than the tank and tail color, I don't believe anything changed between the B and C models. Although the engine looks like bare aluminum, it is actually painted - silver on the barrels, head and valve cover, and clearcoat on the crankcase side covers.

Personally I prefer them just like they came from the factory...

The crankcase halfs and valve cover are painted silver, but the head and cylinder barrel are raw aluminum as near as I can tell (bead blasting would replicate the finish pretty closely). Crankcase side covers are polished and clear coated.
