Thanks

Currently I am doing so much work on the bike and on my job. I dont have to much time to post updated. And also I want to keep some things secret until I finish the bike.

I think I am at 80% of the build. So I hope At the and of January to be somewhere.

Just one thing. Special thanks to Yossef(turboguzzi) for finding me a metalshaper near Milano.

The only thing left for thinking is exhaust. I really dont like solutions you can buy. I originally wanted to make something similar to what Autofabrica made but they made it

Just small portion of things done... I cant post more for now

Amazing.

The control parts (clip ons, levers, perches, trees) look beautiful assembled. The fender is elegant. Are the two splines joining the fender to the wheel carbon fiber or metal?

Also, it looks like the aluminum gas tank is finished?

MessnerMoto · « **Reply #277 on:** December 13, 2016, 07:00:36 AM »

Yes I redesigned front fender. Now it is made from top and 2 lower parts. It is easier to print and it is better fit between brakes and forks. Yes it is carbon bars joining 3 parts together

There are two stainless plates glued to lower 2 parts. This stainless plates protect plastic from heat and also give some structural stiffness.

Than, tail and light are finished

brushed al. But I will redo finish

Show us the tank,nor drawings of it...

SOHC4 Cafe Racer Fan · « **Reply #279 on:** December 13, 2016, 08:36:30 AM »

Outstanding! Yes, let's see some photos of the tank and seat. Based on the models you previously made, I bet these parts look spectacular.

I can give you just one shot for now

Shapely and beautiful. I like the embossed leather with your logo, too.

Nice, can I have it ?

I couldn't afford what he would want for it...how about you Frank?

MessnerMoto · « **Reply #284 on:** December 18, 2016, 01:53:54 AM »

I cant afford it

its not funny....

It is official, MessnerMoto is looking for a SugarMomma!!

MessnerMoto · « **Reply #286 on:** December 18, 2016, 02:25:32 AM »

Will see

MessnerMoto · « **Reply #287 on:** December 19, 2016, 02:49:27 AM »

This is a next step.And maybe somebody can help me. Does anybody have exact measurements of exhaust port openings location regarding the frame. I took some measurements(you can see in pictures) and I think they are not good

calj737 · « **Reply #288 on:** December 19, 2016, 03:01:01 AM »

Wouldn't it be easier to measure the ports with an overall width, then center-to-center spacing, and use the steering neck as a centerline and equally spaced based off that axis? That should land each port in its proper position relative to the frame.

MessnerMoto · « **Reply #289 on:** December 19, 2016, 05:07:17 AM »

you are reading my mind

This is what I tied but if you think about it there are angles measurement involved... Ports openings are angled in 2 axes compared to top surface of the head. But maybe I can stick straight 35mm tube in to a port and then measure closer to neck axes...

MessnerMoto · « **Reply #290 on:** December 27, 2016, 04:56:32 AM »

I managed to measure exhaust port positions relative to frame(with good precision I hope)

One question regarding the muffler exit position before I send exhaust tubes for bending. I am still questioning position of mufflers relative to chain and rear tire. I am afraid that vapor and heat will have bad impact on chain and tire. Any opinions ?

calj737 · « **Reply #291 on:** December 27, 2016, 05:15:36 AM »

That shouldn't be an issue given that while riding, wind will take the exhaust gas straight away. Only while sitting and idling will the chain be subjected to heat radiating from the exhaust. I don't expect you're planning on sitting traffic too much

Exactly the issue is while idling... And I am more concerned with water vapor then heat. As we now more then half of product from gas combustion is water vapor

I don't expect you'll have an issue. Proper maintenance of your chain (lubing and tensioning) will alert you to any issues developing. I see lots of exhausts exiting near chains and tires and don't hear reports of premature wear as a result.

Ok... now 3D print a model of it.

this is #$%*ing awesome!

Yeah but modern chain lubes are great. I don't think that will be an issue at all. If you use a standard RK black chain you'll probably have a bit of rust residue anyway just because that's what they do.

Seriously, push that program through a 3D printer and make 1/10th scale models for us?

It goes directly to CNC tube bending. There is no need for mid steps

SOHC4 Cafe Racer Fan · « **Reply #298 on:** December 27, 2016, 08:03:37 AM »

Straight pipes or baffled?

MessnerMoto · « **Reply #299 on:** December 27, 2016, 08:12:00 AM »

I designed pipes so they can be fitted with
1.375" ID
1.375"x2.88"x8.50"L
2.88"x 1.375"x 2.0"L
12" OAL. MS perforated core w/SS wool wrap.
MC-1375-12-SS

coneeng mufflers. They are really expensive. 100$ per muffler. They are straight cores.... I would like baffled version and cheaper
