5twins replied to the thread ‘77 BS38 running way too lean.The size is 10 x 22 x 2mm thick. You can get them from Suzuki but the price is rather high ...

5twins replied to the thread ‘77 BS38 running way too lean.I'd also like to mention that many of us change the rubber/metal washers on the outside 4 studs to copper or brass. Those studs flow oil...

5twins replied to the thread The reconstruction begins 1977 (Surprise).Yes, I was going to mention that. Granted, we can improve lots of little things on this bike but some, not so much, lol.

5twins replied to the thread The reconstruction begins 1977 (Surprise).I think they all have that "wobble", probably from being run for years without grease. Both of mine do it, one more than the other, but...

5twins replied to the thread ‘77 BS38 running way too lean.I'm pretty sure the torque spec is for lubed fasteners. The newer manuals don't mention it but the '75 and older ones specifically do...

5twins replied to the thread ‘77 BS38 running way too lean.Looking good, but you really need something on the forks, either a fender or fork brace of some sort. That single disc really puts a lot...

5twins replied to the thread Engine Oil.50wt. may be a bit heavy for your lawn mower and snowblower? The snowblower especially, since it's run in quite cold weather. I see an...
-
5twins replied to the thread Exhaust Options.On the 1.5" pipes, that's the O.D., so the I.D. is probably about 1 3/8".
-
5twins replied to the thread Exhaust Options.The 1.5" headpipe is supposed to be the ideal size for this motor, not too big and not too small. The O.E.M. 1.25" pipes are rather...

5twins replied to the thread tapered handlebar rubber mount bushes in the UK..I'm not sure about where you can get new ones but if the old ones are still intact, many times you can just shim them tight again by...

-
5twins replied to the thread ‘77 BS38 running way too lean.Sounds like the throttle cable is messed up, hanging up somewhere.
-
5twins replied to the thread Exhaust Options.I prefer a 2-into-2 system. 2-1 systems can be difficult to tune for because most are made to just fit the bike in question. Header...
-
5twins replied to the thread 1981 XS650 Cafe Project tips.If those are standard intake manifolds, they won't hold up long without the metal shrouds on them, they need them for support. If...

5twins replied to the thread Feeling insane please help. Wildly Asymmetric mix screws..Yes, if the float level is off, the mix screw will have little to no effect.
-
5twins replied to the thread Clutch worm gear.I use the heaviest grease I've got, which happens to be Sta-Lube Premium Red ...... The grooves in one part mate up with the ribs in...

-
5twins replied to the thread Feeling insane please help. Wildly Asymmetric mix screws..If your floats have the tube "shim" in the pivot then they sound like they're originals. Many of the aftermarket ones don't have that...

5twins replied to the thread Introductions.Yes, this is a wonderful bike to learn on. It's pretty easy to work on and most things are right where you'd expect them to be. It's...

5twins replied to the thread Addressing the front disc brake after years of sitting.Another variation on assembling the caliper "butterfly" fashion is to place a small square of aluminum sheet over the crossover hole...
-
5twins replied to the thread Feeling insane please help. Wildly Asymmetric mix screws..Have you ever removed the mix screws and checked/replaced the little o-rings on them? If not then you probably should. The o-ring goes...

-
5twins replied to the thread Feeling insane please help. Wildly Asymmetric mix screws..Well, it might be. I find carb adjustments seem to be easier and work better when the bike is sitting level on the centerstand. The mix...

5twins replied to the thread 1978 BS38 breaks up at 2500. Video included..I think I'd remove it completely and try to expand the inner end a little to get a tight fit again by driving a small, gently tapered...

5twins replied to the thread ‘77 BS38 running way too lean.Yes, the BS38s use the very common and widely available N102.221 "small round" mains ......

5twins replied to the thread Question wiring stator to solid state reg/rec.Here's a labeled pic, courtesy of Jim I think ......
-
-
5twins replied to the thread Question wiring stator to solid state reg/rec.Just make sure the screws aren't too long. If they stick out the back of the stator much they can hit the rotor and really mess it up.
-
5twins replied to the thread Question wiring stator to solid state reg/rec.OK, what I meant by him needing to ground both black wires, the one from the inner brush and the one from the reg/rec (in post #23), is...
-
5twins replied to the thread Question wiring stator to solid state reg/rec.Yes, it appears that MikesXS drawing is wrong, or more correctly, incomplete, because it doesn't show the brown wire. The regulator...
-
5twins replied to the thread Question wiring stator to solid state reg/rec.The brown wire from the reg/rec gets connected to a switched power wire in the harness, something that's only powered when the key is...
-
5twins replied to the thread retaining the nipples in BS38 carburetors.I'd put some sealant (Yamabond) on them then tap them back in real good.
-
5twins replied to the thread Question wiring stator to solid state reg/rec.Since the combined reg/rec you got is made for the '70-'79 alternator and brushes, you really don't even need the nylon screw mod, you...
-
5twins replied to the thread Addressing the front disc brake after years of sitting.Use a large C-clamp to compress the pistons back into the caliper a little bit. This will break them free. Then blow them out with...
-
5twins replied to the thread Addressing the front disc brake after years of sitting.The Yamaha brakes are pretty robust, so you may not need to replace any seals or other parts, but you definitely want to take it all...
-
5twins replied to the thread Second XS650, 1977 Standard.Just let me clarify something here - the spot where you set the points gap, where the points are open the most, won't line up with the...
-
5twins replied to the thread ‘77 BS38 running way too lean.OK, you definitely have '76-'77 carbs there. Yes, it's tough to read the size of the needle jet unless you pull it out because it's...

5twins replied to the thread need XS2 carb advise.It's a grease made specifically for use on rubber. It's vegetable oil-based, not petroleum. It's not readily available in the States...
-
5twins replied to the thread ‘77 BS38 running way too lean.One more thing - the float level spec for the '76-'77 carb set is 25mm. If you're set at 24mm, that's a richer setting.
-
5twins replied to the thread ‘77 BS38 running way too lean.Yes, downsize the mains as well. 140's are way too big. And did you ever take pics to show us? And have you checked the needles and...
-
5twins replied to the thread need XS2 carb advise.I guess it's not unheard of for the shaft to wear the hole in the carb body, and it mostly happens on the one near where the cable...

-
5twins replied to the thread Second XS650, 1977 Standard.It's possible your advance unit is assembled incorrectly, and that would throw the timing off 180°. See the end of the locating pin slot...

-
5twins replied to the thread ‘77 BS38 running way too lean.I've heard the JBM manifolds are strong enough to run without the metal shrouds. But, do save them in case you ever do find nice...
-
5twins replied to the thread need XS2 carb advise.Are the carbs synced and is the idle speed turned up enough on the right carb? If it's set too low, that carb will be effectively shut...
-
5twins replied to the thread Second XS650, 1977 Standard.Unfortunately, that's kinda typical, lol. You're in for a treat dealing with the dual points system, it can be a bear to get set...
