I understand the allure.  I have a buddy who was stuffing a modern Yamaha EFI engine into a 550 frame. 

You might also want to add some modest bracing to the frame, since it was not necessarily designed for 60 hp.

Ya know, there was only one spot I'd identify as a weak point which was in the backbone that i've already made plans to add a little meat to, but otherwise it seems ok to me, mostly because even though it's a little more power, there's also a lot less weigh to put stress on it.

I had a few minutes today and I strated screwing with the ugliness of that fork brace. I figure if I remove the receivers for the boots, then smooth all the hard edges out, it'll look way better. I'm also going to polish it to match the forks instead of standing out. I always have a hard time with crap like this. Sure, it's going to look far better, but it won't function any better, so the 5-10 hours into the one piece is purely for looks. That's why the battery box is a rectangle sitting in the frame instead of something pretty. My cnc buddy had to convince me to make a cover for that too.

If you think that fork brace is ugly, try a TKAT brace -- very industrial, over-engineered but effective.  Yours looks almost like a bare metal Tarozzi.

As for bracing, I think you can do it with a few discrete pieces and even a few speed holes for lightening.

Since you're trying to shed grams, I'd ditch the centerstand and upper/lower covers on your shocks.

The shock I've been dying to use so it's only 1 pound total, I will deal. The centerstand has to stay there's no other way to stand the bike lol!

[SOHC4 Cafe Racer Fan]

I was considering running only centerstand on my next project but there are too many hills locally.  I was worried about parking on a hill with only a center stand.

Starting reprofiling the fork brace

[SOHC4 Cafe Racer Fan]

Jag,

Did you "start" with a Tarozzi brace?

[jag767]

Jag,

Yup! Trying to slap the ugly off of it

[RAFster122s]

You don't like squared edges without radii/much edge relief and machining without a lot of post machining finish work?  What kind of edgy machine are you trying to build with fluid stuff everywhere?  Looks like bondo?

You didn't consider using epoxy putty? Are you going to attach a fender like Godffrey does with brace beneath fender and going down an 1" in height on tire with 19"?
Probably already pointed out in this thread if not somevother thread I have been reading or following.

Fortune cookie I kept the fortune from reads,
" Advice is like kissing. It costs nothing is a pleasant thing to do."
Reminds me more of, " Opinions are like aholes, everyone has one."  A longer version of that ends, "... and no one wants to be around them or hear them "speak"."

Believe it or not, another fortune cookie fortune read, " What's more important - your goal or others' opinion of your goal."

I have no wisdom so I should shut up...no one wants my opinion lest they wish to consider me an ahole?

[jag767]

Lol. No front fender, 18 inch rim, and no bondo because i am going to polish it once i get a shape i can live with the goal is to have it blend into the forks like it was always there.

New oil pan

[RAFster122s]

No need for windage tray around pickup for pump? With shallower oil pump you will have to reduce the volume of oil so your crank does not emmerse itself in the oil.  That leads to foaming/frothing and cavitating pumps which can cause oil starvation in the motor as well as possible oil pump failure.
Just making sure you are not risking causing a problem solving another.

The bottom if the case isn't open to the crank, i'll take a photo. The crank is enclosed other than the lead for the oil feed. So in theory the exact same volume of oil will be used and should be fine. The pump itself is unchanged, and the oil level itself is unchange. All I did is change the shape since I won't be needing the cat which normally sits next to it.

Everyone has one and they all stink.

Been busy, but my buddy started cncing my redesigned oil pan

[SOHC4 Cafe Racer Fan]

I'm a sucker for the CNC-porn.

[RAFster122s]

Pretty nice.  So you have that swirl feature in the oil pan...little known performance mod
He may need to mirror that swirl for south of the equator...
 (teasing)

Looks really nice!  Do you plan on having it be sent out for a clear hard anodized coating?

Thanks! I'm not sure that's necessary, and the outside will get painted to match the motor. It'll end up being one of those details that done right no one will know is there.

[jag767]

Have to take a month break on this bike, since I have a customer bike to do. That's the bad news. The good news is the money I make from the customer bike will pay for the rest of this bike  . I cleaned up the little shop and everything

[jas67]

Wow, that's got to have left a hell of a huge pile of metal chips!
Looks great!

[RAFster122s]

Was teasing/joking about the swirl...there would be no impact from it...  too bad that bike porn is covered up with paint.  Nice and clean shop.

 That is quite a favor he us doing for you!  How much would it cost if he was selling them?
You should put it in projects, more people wood see your bike.

Heh I have no clue, but it took 2 hours to design, 2 hours of setup, and 2 hours to run. So not cheap lol. I thought projects was only for 4's....

Progress:

[SKTP]

WOW...this thing is amazing
