Yeah, when it's done right, I think it looks great - it's a nice way to "transform" the look of the rearsets, on a bike where you don't want/need to invest in an aftermarket set.

 

A countersink is one of the tool bits that you really gotta dish out some of that hard earned cash to get a good one, personally I wouldn't even try that without a drill press but that's mostly cause I don't have steady hands. Specially with aluminum, the less it has cutting edges the less it hops and chops, and if you don't know, as odd as it sounds, with aluminum, use a spirit like rubbing alcohol as cutting liquid to ensure smooth cut.

 

Yeah, the bits I got were pretty cheap, so I know I've got to go to a different place, with more of a selection, and spend some good money.
And yes, I would really like to use a drill press, which is a near future purchase, but if I can just come up with a good bit, I think I can make it work... the nice thing is that I have two extra rearsets to practice on, and get the result I want, before moving on to the final job.

That's interesting about the rubbing alcohol - I was using a cutting oil, but I would have never thought of alcohol.

 

One time when I bought a countersink bit I was perusing the options at a local harware shop and Thought that the more the blades the better, came home and made a few hexagonal holes with it until I threw it to the nearby field and went back to get a better one from a tool shop...

The first time I heard about the alcohol on aluminum I thought I was being pranked, I mean how can a solvent work as a lubricant. This one guy at work was drilling alu and was pouring some liquid to the drill bit from a Sinol bottle ( the leading brand here everyone uses in those decorative tabletop fireplaces and for rubbing alcohol) I immediately asked him what he had in that bottle and he replied "sinol".
No, seriously what's in there?
"Sinol".
I was sure he was pulling my leg until one day I went to the tool shop again and happened to ask the seller could there be any truth to it or was the guy yanking me, without batting an eyelid the clerk pointed to a basket near me full of ready made squirt caps to fit the sinol bottles. Apparently it has to do with surfsce tension and the alcohol penetrates better to the drillbit without mushing up all the shavings.

 

Since the race bike's wheels are inside, so the slicks aren't exposed to the extreme low temps, I finally popped off one side of each slick, and got those right-angle race valve stems installed.

Rear:

 

Also, I neglected to post this before, but this is one of my favorite angles of the F2.

 

That is a gorgeous angle! By far my favorite. I like the right angle valve stems too. Definitely a smart investment. Gonna have to order me some lol. Man, all the parts already laying in my kitchen doh!

 

You mean new stuff that hasn't been installed yet? If so, get to work man!!

 

Yeah lots of new stuff. Complete set of gaskets, scored a set of good transmission internals for 35 to fix the second gear issue... And the list goes on lol.. works gonna start soon. Gotta go to Kentucky Tuesday to help my mom move then it's time to start.
