CB77 badges not from Thailand.

Post by chrisnoel » Tue Oct 08, 2013 8:04 am

Well, have gone two rounds now with the plastic e-bay badges not from Thailand and I can't screw them on without breaking them. Second go round I put a bead of silicone on the badges and screwed in as lightly as possible. Five min later I noticed the bulls eye crack pattern around one screw again. Suppose this is better than the first go round as I broke all four screw holes just from making them snug. These things are for display purposes only in my opinion. He claims that his color of gold is more accurate than the Thai badges but if they break when you sneeze on them what good are they? Any one know if they Thai badges hold up better?

Make sure the holes lineup, if not file the holes. Use small rubber orings as washers between badge and tank. Lightly tighten screews. Never use loctite.

lock tight.

The holes did line up but I didn't think about using O-rings. Also, since I left the screws so loose, I did use a bit of lock tight. I'm thinking if I had used O-rings I would have had to tighten the screws at least as tight as the first go round and they would have all been wrecked again. Too much effort to make something so worthless keep from breaking. The ones I have installed for now will work until something bumps into them. Then I'll pick up the bits and look for something else.

I had the same problems with Ray's badges on several bikes. they look great until they crack. I found by filling the hollow in the back of the badge with epoxy (like the originals) they will hold up well and not crack.
Good luck

Loctite on plactic bagdes

Post by Tim Miller » Wed Oct 09, 2013 10:13 am

Loctite causes acrylic and other plactics to crack. It's some kinda chemical reaction. Don't ask how I know. )-;

The metal (later standardized Honda) badges that came on our Dream had countersunk holes with oval head screws. The plastic reproduction badge set we got from Tim McDowell at Classichondarestoration.com (pricey but AWESOME!) have counterbored holes and came with the proper chrome plated pan-head screws. I imagine if one were to use a countersunk oval head screw in a plastic, counterbored badge, many cracks would quickly ensue.

I've cracked a few of Ray's badges too... Use the O rings and that really helps. On all of my bikes I also put a dab of silicone in the screw holes so the screws don's back out while you're riding... Works good!
