Tank Coating, part deux

My tank is being painted, thanx dad.
We had a big can of red, so that's what color the tank is going to be. Decided to remove the old emblem mountings as they were pretty mangled, probably will look better with a classic set of honda wing stickers and some silver stripes running along the length, just like the old RC tanks.

I'm liking the way this looks, might just put it back on my SS50Z moped, to make it look more like the way it used to, long ago:
Same tank by the way, one or two crashes earlier...

122cc motor cylinderhead

Done a little bit of work for my S90 in between all the other projects.
The plan is to build another engine, bored and stroked to 122cc by using ATC110 parts, cylinder, crankshaft and head. Only the ATC110 head has separate valve seats which are pretty thin, which means there is not enough material in them to install a bigger inlet valve.
A while ago I recieved a head from someone, probably C90, that had a full cast in combustion chamber, much easier to put a larger valve in there, but this head didn't fit the ATC110 cilinder.
I had to machine the space for the top of the cilinder, and also the studbolt hole where the oil comes up, as the ATC110 has a large rubber collar there and the C90 head didn't have a space for it.

ATC head on the left, C90 on the right.

the valve I plan on using compared to the original S90 inlet valve

when made to fit the head, this motor will breathe a little easier.

little changes

Some little changes have been made to my SS50, just a crappy pic in the dark, but it's wintertime, it gets dark soon and I didn't have my exhaust mounted in time to make pictures in the light.
Custom painted tank emblems, exhaust that came off my motorcycle, different seat, CB50 shocks and a slightly different taillight (short lens type)
