Fuel tank cap and flange

[SBMike]

I’m not sure what it’s called but the flange that actually screws into to tank. And then the cap screws into that flange. What do you put on the threads of that flange, if anything before you screw it into the tank?

I looked in the manual but I didn’t see that covered anywhere.

Gas cap and paint saver comes as one unit. If you have any paint damage around the hole, post a picture, I can take care of that for you.

Paint saver

H?ey was wondering just had tank painted so to reinstall paint saver do I need the special tool or just screw it in? Any other points appreciated!

There isn’t anything wrong with mine that I know of. The guy that Powdercoated my frame and oil tank talked me into powder coating everything. ( which was a mistake and a subject for a whole different tread). He put powder down into the tank threads because he thought it would “seal the tank saver threads”. But the tank saver wouldn’t screw in. So I had him remove the powder coating and I’m having a different guy do the paint job traditionally. But the tank saver has to be put back in the tank eventually. Does it get some kind of thread sealer? Exopy? Rtv? It seems it would something to hold it in so it doesn’t unscrew with the cap.

What did he do, powder coat over the paint? I didn't know that was a thing.

 

[SBMike]

No he took it down to bare metal. He was just suppose to powder cost the frame, swingarm and oil tank. And all the tins were going to an airbrush guy that was going to paint everything first then airbrush. But the Powdercoat guy convinced me and the airbrush guy to powder coat first, then airbrush and clear. Which might have been a good plan if the guy knew how to powder coat. It was a mess. Bumps, and pin holes everywhere. I was looking at the airbrush guy as he was trying to figure out a way to tell the powder coat guy that the finish was junk. They did tests to make sure the clear was going to stick to the powder coat. Now I’m caught in this mess and hoping my bike is done by spring.

I feel for you. Keep us posted. Eric will gets you fixed up with a new gas cap and paint saver. You can put a little ultra black silicone on the rubber gasket on the paint saver when you install it

So is it jb weld on the tank saver threads?

I've heard that they used jb weld at the BDM factory when they put the paint savers in.

 

[SBMike]

Thanks, I was wondering if there was something different that people came up with. Maybe something as effective but not as hard to remove in the future.

Just my personal opinion on the paintsaver: ditch the stock as they are absolute garbage and allow fumes to condensate on the underside of the gas cap which will then drip onto your paint. Also the rubber seal on the stock paintsavers is not correct for the application on our tanks. There are plenty of better choices offered by the aftermarket. Sorry I don't have pictures of the difference when I changed mine out, but I have seen far too many examples of bubbled paint due to the shitty stock paintsavers.

I have the stock paint saver on my k9. The paint had bubbled up around it. Mr. Wright (on this forum) made a paint saver ring that goes under the stock ring. I scraped the bubbled paint off, sealed the original paint with jb weld, applied a fuel resistant adhesive (permatex brand from advance auto) around the top of the gas bung hole, placed the new ring over the bung hole, and screwed the original paint saver back in the tank. Here is a picture of my finished tank saver.

P.S. I did not use the original gasket under the paint saver. The permetex set up as the needed gasket material.

I agree to ditch the paint saver (ironic name) as they cause more trouble than they solve.

Many aftermarket solutions.

 

[SBMike]

Does anyone have a picture of a K9 tank looking down into the gas hole without a tank saver in it? At the bottom of the bung is there an offset hole? Maybe offset towards the front?

 

[Mr. Wright]

Yes, and one of them looks like it has a pipe in it. That pipe runs down to one of the plug, on the bottom rear of the tank. It was designed to be a vent tube, but it is not used on these bikes.

Thank you sir.
