PAINT PROBLEMS
« Reply #45 on: February 12, 2020, 11:44:42 am »
First time using single step paint.
This is Starfire Acrylic Enamel Auto Paint - Merlot Metallic.
mixed 4-1 reducer.  Looks shiny from a distance but not "wet" looking. Up close looks very rough.
I've read that your not supposed to wet sand Acrylic paint  but it looks terrible. like this.
Anyone with experience with single step acrylic enamel? What must I do to get a glossy finish?

On a slightly better note.
I picked up my seat today. I am very pleased. Much better that what I had glued together.  He added more padding and smoothed out what the previous owner had done.

lot better second try. Used a slower reducer and less air pressure.  But I am done with single step paint. It's much more problemetic than base/clear. And with clear coat its easier to fix your mistakes.

Not so cold today so I got a chance to work in the garage. Finished painting, Welded up an extension and added a small seat. Will never use the extra seat but it makes it look more balanced.

The tune is all messed up since I added the mesh screen in the carb throat. I need to go on another tuning ride when the weather warms  up.

What's with the mesh screen in the carbs?
Thank God for good men willing to do extreme violence.

Well I detected a leak a week ago. Not a big one, just a drop every 10 seconds or so.

It turns out the fuel coming from the injectors was not atomized like you would think. It actually looks like a group of squirt guns aiming at the throttle plate. Well at idle the throttle plate is nearly closed so those streams of liquid were splashing back and collecting in the seam of the air-box boot and eventually dripping.  The screen mesh breaks the streams into a mist that does not splash back and stays inside the throttle body.
You cans see the difference in the video I posted. In the first part of the video you can see the output of the injectors in a stream of liquid. In the next part of the video  you can see the difference the screen mesh makes to the the fuel spray. The last part of the video is in slow motion and you can see the screen breaks the fuel into a mist.

The screens change the volumetric efficiency of the cylinder slightly. So I have to make minor adjustment to the VE table to make up for the change in air flow.
