I'm about to remove the "Yamaha" lettering from an XS650 primary cover. I'm building a jig to hold the cover in place for my vertical mill can remove the very shallow writing. I'm then going to use a belt-sander to restore some roundness to the cover, as the mill will have just left a flat spot.

Here are two photos - the first one is of my old XS650/750 racebike (machined for external plumbing) with ugly-ass text in place and the second, swiped from Bob Bertaut's website, shows a cover with the text removed. I didn't do the 2nd cover; it's just there for demonstration purposes. Many people simply fill the female letters in with JB Weld and paint over with glossy black paint, but then you can't have a shiny aluminum cover.




Here's a question for other XS650 owners, or owners of any Japanese bike with company name similarly engraved into engine covers. Does anyone do this commercially? If not, what would such a service be worth to people on this forum?

I've got equipment, a little spare time, and a desperate need for cash. I'm a (damn near) starving third-year law student and could use a humble source of income that I can then invest back into a chopper project.

Any insight, advice, or cash donations graciously accepted!

How long does it take you? I am sure that there are quite a few out there that would take you up on this for the right $...

When I had the XS, I would have been interested in that if the price wasn't too terribly high. I never got that far on the bike though before I sold it.

Standard rate here in Utah for machine work is $70 an hour. I think if you could keep it around $70 you should have no problem defacing the covers :)

Hey Sporticus,

Im almost positive that I've read that this is REALLY easy to do, that the metal is pretty soft and since the letters really areant that deep, they go away pretty easily. In other words, looks bigger than it is. Curious to see how true this is though.
Good Luck!!

You can fill the letters with alum filler rod and a TIG torch.

I suck at welding aluminum and have filled holes in fork legs from cutting tabs off and such. It was pretty easy to build up a lump of filler than shape with a file and sander.

Might be a lot quicker and easier than machining them off and re-contouring.

A few years back I was restoring a 74 TX650 and was hanging around the 650 forums. Since Yamaha was a new subject for me, I started hanging around the old XS650 list and corresponded regulary with many of the members. One of the was Bob Bertaut and I started watching his site on a regular basis. Since I had an ever growing pile of excess 650 parts, I tried removing the YAMAHA from one of the "parts" covers following the posted directions. Actually, it worked great! I can't weld aluminum for shit, so for me it was easier to sand and recontour the cover then it was to weld and try to dress up the resulting mess. LOL!

No TIG and marginal skills with MIG. I'd be afraid that there would be color differences and the fill would be too obvious. Is this a legitimate concern?

Like Apehanger Hank, I too saw Bob Bertaut's documented "Yamaha" exorcism. I was active on the Micapeak XS list when I was racing my XS powered sidehack and 750 cc solo bike. I recall Bob saying that there was plenty of material that could be removed without affecting the integrity of the cover. I've seen a lot filled with putty and painted black. I like to make things difficult for myself.

I should have the time tomorrow to fixture the cover and mill away.

I have removed the "yamaha" on quite a few xs650 sidecovers...I have removed just the bare minimum to get the lettering removed and cleaned up the scratch marks...It does get the side covers pretty thin...

As stated above, you can get blank polished covers already from MikesXS. Then it would be just one step to engrave them. I'd rather start with a blank than have to screw around with filling a stocker to start with.

I personally like the look of the Yamaha removed...Looks cleaner...If it wasn't so damn ugly i would leave it on...I love to piss off the RUB's with my $400 piece of jap shit...anyone dumb enough to think an XS650 is a triumph isn't anyone I want to associate with anyway...

I ground mine off with a 4 1/2" grinder and polished it up. Piece of cake.

Probably not worthwhile to offer as a service here, being that most would do it themselves, but you'd probably do OK on Ebay.

But I'd suggest buying up 3 or 4 of them, grinding and polishing them, then offering them on Ebay with or without a core charge for their old covers.

One thing I did learn when welding fins on the other cover of mine, the aluminum must have some sort of coating. It welded like shit- lots of bubbles. That made me decide on grinding rather than weld/ filling it.

My 2 cents.

Here ya go, Cabbie. They're pretty amateur looking with the pits, and probably not worth the trouble of doing. Live and learn...

You know...as cool as they look (and we all know I get distracted by shiny things) I'd almost rather see "Yamaha" left in there....hell make it BIGGER and wear a t-shirt that says something like "Fuck yeah its a Yamaha."

I dunno...I know its just me but when its kind of like wearing what was referred to as "birth control glasses".
Kind of a "Hell yeah, I wear glasses. It doesn't bother me so it shouldn't bother you!" kind of attitude.
"Yamaha" "Honda" "Kawasaki" hell even "Yamasonda" or whatever it just makes it that much cooler.

I know, I know...its just me.

*again this is more proof of why I shouldn't type without enough coffee.

Rob, the fins look good man! Havent seen that on an XS before. Nother question for ya, what/ how did you do your "oil" tank/ elec box? Looks good. I need to hide my wiring and have quite a few ideas, but Im not sure yet. Seen em done a bunch of ways, just curious.

Thanks!
