I also use a special dedicated screwdriver for prying the seals out. It's a big old square shank flat blade with the tip rounded off...

Yes, as you've discovered, you need to protect the top of the fork lower while prying the seal out. You can make up a simple protector...

Black fenders, fork legs, and carbs indicate you have an '82 model.

You can also use the original anti-kink and protection springs. They won't fit on that auto line.

Except you want/need the larger 1/4" stuff ..... https://yamahaxs650.com/product/black-rubber-fuel-line-1-4-x-25/ This is wonderful...

Yes, the extension has the "wobble" feature, not the socket ...... You can get a set from HF ...

Yes, you absolutely want to pull the jugs. If you don't, there's no way to center the new guide when you mount it. There's "play" in the...

Yes, I would recommend looking for one that's closer to stock.

Sounds like you may have a bad coil. Many times when a coil goes bad, it acts up when hot but works fine when cold. A nice cheap...

Yes, it's accepted practice to use 3 and 6 on any year 650. My '78 speced .004" for the intakes but when I tried it, they ticked like...

You may also want to get a different spring, one that's shorter. That way, you can move the lower spring anchor point up closer to the...

I would start with the old standby - 6" from the top, and use the stock 10wt. fork oil. I would also do the "Minton Mods" to the damper...

Yes, I also don't like that Shinko 712 front tire. It doesn't feel right through about the 30 to 40 mph range. I recently got a Duro to...

Well, color me both surprised and impressed, lol. The XS Performance pods seem to work fine with no break-up or stumbling through the...

I would finish your Mods by adding UNI pods and then trying 130 and 132.5 mains. Both sets of '76-'77 carbs I've used were set up this...

I've been running the Walmart brand 20W-50 for many years and have no problems. It's cheap and one of the Walmart employees told me...

Yes, I adapted the "check/adjust while the engine idles" method from the SR500. The factory shop manual for that bike gives the static...

The UNI air filter you want for the BS34's is the UP4229 or UP4229ST (dual layer). These are 4" long and all foam (no end cap). The...

Yes, I've repaired several older stands myself. They all need to be braced or they will eventually break. I wouldn't have cut up a good...

The TX750 and 500 sprockets fit the 650 rear wheel, same bolt pattern and center hole. I'm getting away from running stock rear wheels...

48-52 teeth is pretty low I'd say, maybe too low, lol. You can readily get sprockets in the low 40's (from a TX750 or 500). Maybe start...

Yes, I guess it could be the headlight safety relay. With the bike running, test the voltage on the blue/black wire coming out of the...

Yes, I would recommend an original Yamaha seal (or an ARS brand seal) but I can't recommend that aftermarket pushrod. The one I got wore...

Yes, great deal, and the bike looks to be in very good shape. But these all need a good going through, they're 40+ years old after all...

Yes, a used one from eBay. I look for a set of three from a Goldwing 6. You can usually get them for around $30 ...... I try to find...

For a coil, you can use a Honda MP08, quite cheap and very reliable.

What's a jump box?

OK, I assume you have BS38 carbs? The UNI filter for them is the UP4200 or UP4200ST (dual layer). Here's one mounted on my '78 ...

Yes, the caliper mounts on the '76 and older 34mm 650 forks differ from the '77 and later ones because those older forks use the early...

The stock head gasket is .048" thick (about .043" compressed). The Athena head gasket is thicker, about .060" thick, so would reduce...

Yes, slightly smaller than the original (14mm in your case) is better. I watch eBay for used ones from other Yamaha models. The benefit...

To avoid the possible interference issue with the dust covers, I simply eliminated them and installed fork gaiters instead ...... I...
