I've always used tapered stones in a die grinder ...... But I recently got some carbide burrs like GLJ uses so maybe I'll try them...

I'm thinking of trying to make some "D" port inserts from the ends of old XS500 headpipes ...... I've already made inserts from old...

Just be aware that most of us use MikesXS as our very last resort, lol. Their prices and shipping costs are quite high compared to most...

I always run high test in all my bikes. I tried Regular in some of them and they pinged with it, so I went back to the high test. I now...

You said you cleaned the carbs but you may have missed the choke jets. If they're plugged, the chokes won't work and the bike will be...

I don't recall what size the pipe was. I just found one with a slightly smaller diameter than the bushing I.D. That allowed me to pass...

I've always been able to just drive them out with a long piece of pipe and a BFH, no cutting with a hacksaw blade required.

So Gary, with the stuff you listed, I assume you're going to try to make your own screws?

I've found my '83 with it's painted head and jugs runs a bit hotter than my '78 with the "natural" finish.

I see room for lots more shelves. You can never have too many shelves, lol.

I did get "fancy" with mine, lol. The steel plate that the head mounts to has a piece of aluminum riveted to one side to protect the...

Where did you get a small enough 4 bolt sprocket?

I think you're SOL on this one. The front wheel has a narrower hub and smaller disc. The rear wheel uses a smaller diameter axle and the...

Yes, they are pretty "rough" from the factory, kinda like the lunar landscape, lol. After I smooth them out, I rough up the intake...

Only the very early models had needle bearings. Later models switched to what Yamaha called a "labyrinth" seal, which is nothing more...

On that carb you're repairing the post on, I would recommend changing to a Suzuki pivot pin. The Yamaha pin has quite a "step" just...

Yes, I've found stock clutches on pretty much every Jap bike I've owned slip. I "fix" that by installing HD springs.

As far as stock clutches go, I actually prefer the later 6 plate unit. The original 7 plate clutch in my '78 always let out and engaged...

No Pete, you've misunderstood me I think. The one I worked on and "fixed" was a RIGHT side switch, like this one ...

Pete, if the headlight on-off switch has been moved to the right control assembly on that '80 model, enabling it may be very simple. I...

I'd say you're good for a while. Do plan on changing the front guide out eventually though (start "gathering" parts, lol). It's not a...

OK, it looks like the lower rear mount just uses a simple U-bolt around the frame? Thanks for the pics. My dealer used to sell Suzukis...

Well, some pics of the lower rear mount would be good. That's the only one I can't see in any of the pics you've posted so far.

Interesting, no wonder I couldn't find any on eBay, lol.

Yes, very nice. Did you add those mini crash bars or did they come on the bike? I've never seen a set like that. Drill holes in the...

Yes, that would be my best guess. All the ones I've run across are metric, and all the aftermarket mirrors for the 650 are metric as well.

As far as shock spring compressors go, many years ago I made up a couple of fittings for my hydraulic press ...... The one with the...

Yes, I believe that front tire inflation tip came from Dr. John, a guy who used to endurance race Guzzis, or maybe from that Guzziology...

Yes, when I had my MG, I stored it the same way, with the front wheel elevated, because Moto Guzzis more heavily load their front ends...

Geez, all that stuff costs more than I paid for the whole bike, lol.

For a jack, I highly recommend the Blackjack 1000. It was designed for use on a lift but works fine on the ground too. I have one and...

So what's correct, the sticker or the actual markings on the battery? The sticker is the way a '75 650 battery should be. So let's see...

Just be aware that you may have to fool around a bit with the steering bearing adjustment because applying that final torque to the top...

Yamaha continued to install the nubbed arms for a while after '73 but eventually stopped using them (probably when their supply ran low)...

Take a look at gggGary's rotor offset pics in post #3 and you'll see that GeorgeOC's offset measurements are to the inside of the discs...

If you don't break the "seal" (allow the cylinders to lift off the block), then I don't think you need to replace the base gasket. With...

In my opinion, putting the skinnier 34mm forks on would be a giant step backwards, lol.

Yes, '77 was the first year for the 35mm forks, so you'd want a '77 or newer fork. The '77 tubes are very nice because you can remove...

Well, at least the diaphragm is replaceable (no need to buy a slide/diaphragm assembly).

If your '77 is a Canadian model then yes, it would have a L/B wire coming out of the safety relay. There is a '77 Canadian wiring...

You probably just need to tighten the T install. The seal is made by the T being pushed tightly into the holes. The bottoms of the holes...

I don't think that will work because the chain adjusters are right- and left-handed. The left one has a smaller hole on the outside that...

Syncing individual throttle cable equipped carbs is a two step process. First you must set the idle speed because the idle speed...
