Yeah I've got those on my Yamaha, they work great! But the Honda has solid axles and no spool nubbins on the swingarm.

The obvious first step is to clean all the gunk off the bottom of the swingarm but I'm not sure that will solve it completely. I use the non-spool option to lift the Yamaha to remove the rear wheel or adjust chain slack and have never had that issue.

Oh lol I didn’t put two and two together and thought it was the MT-07, not the 919 :o:

I’ve also seen some that bolt onto the end of the swing arm depending on your chain adjustment.

Edit: here

I *finally* put new tires on the Honda today, and learned a few things:
- the tire changer I bought was 100% worth the money but it also didn't eliminate the need for tire irons, the rear went on fine but the front is just too tight. I still scratched my wheels up a little. I need to get that part figured out before I buy a bike worth keeping shiny
- Remember to balance the wheel before you put it back on the bike, idiot
- The swingarm will slowly slide down my rear stand until it falls off. I got lucky and it came down on the kickstand but it's going to make maintenance extra annoying til I figure out a solution.

You can get tyre changing guards, they are bits of plastic with string attached that go on the rim, you fit the tyre and pull them off with the string. Use lots of lube obv.


A wheel chock and a small platform jack will make your life a lot less fraught without having to put more parts on the bike, with the bonus of now being able to take anyone's tyres off.

I've been putting off tightening the chain on the Bonneville, but today I fought the right-hand muffler off as is needed for that, and then learned I need a 27mm socket for the axle bolt and my biggest is a 24.

Better luck next week, chain.

The $75 Moby sludged up like crazy at the beginning of spring and I just got around to loving with it.

After cleaning the sludge out of the carb, I decided to tackle the tank. I love mopeds but hate rusty tanks on them because I can’t take them off to shake them with abrasive inside.

Pressure washer, 100psi of air, brushes through the gas filler and petcock fitting all working together to knock chunks loose and drain them out the bottom.

Yeah pretty much. We have the Mama Tried Flat Out Friday here in Milwaukee and I love watching the Hooligan class and all those bikes. A friend’s uncle died and his mom sold his sporty to me for like $2,000 so I said gently caress it sure I’ll ride it then make a cool street tracker out of it

Back to the tenere carb.

I tested Vs throttle %. It runs good on idle and up to 1/4. The stuttering and dropping rpm is above 1/4 up to and including 100% throttle.




I removed the carb and checked needle positions. Both are on middle 3rd notch. The marking on the needles and notch is stock position according to the manual.

This is always basically the extent of my contribution to carb chart. Seems like you’re on the right track. I tend to shotgun parts at carbs though because needles and jets are relatively cheap.

It sounds to me like they're not getting enough fuel in the bowls and it's starving for more fuel once it gets beyond the pilot circuit, but I've never worked on one of these two-carbs-share-a-bowl deals. Could be the filter restricting it or the float height isn't correct.

Fair point. But can’t you tell if that’s true just if the stuttering is immediate when you roll on or not? If not, then no because it should have at least sufficient fuel in the bowls to make the initial roll on work?

Said another way, I always thought that the symptom of that kind of issue was that it was working OK and then it stops vs just never working OK.

Yeah not sure, I'm looking at that diagram and trying to understand the nuances of such a setup. I see what appears to be a sync screw, have they been synced?



If you're confident the carbs are baselined (factory settings, factory jet sizes, factory needles, float height correct) I'd look elsewhere.

Adjusted the primary needle one step towards lean, stuttering seems gone.
Going to take a test ride for it to hit operation temp properly, pluss test 100% throttle. Don't want to do extended test of that parked with an oil cooled engine that has no oil rad fan.

Edit: better, but not 100% gone. I can get stuttering above 1/2 throttle but not 100% consistent, plus a little popping on de acceleration.

You could go down one size on the main jet, are your air filters clean though? No restrictions? Sounds like you almost have it anyway. Valves are ok, right? Checked them on the maintenance cycle? They can mask as a/f problems when they start going out of spec I feel, especially ones that tighten instead of loosen and don't fully close. So can a small timing chain jump too.

Air filter looks good, its a foam style one. but the age of it is unknown. it has foam oil, so it's not bone dry. I got a spare I can swap to.

Tightened the bonneville's chain today, and cleaned it while the peashooters were off because the chain's a huge pain in the rear end to clean with the mufflers on. FSM says to do this every 200 miles, hah- I'm doing the full chain clean-and-rinse twice a year at most.

Also noted some rust on the mirror stems already, this thing's only 2.5 years old and it lives under a carport 2 miles from the ocean, at this rate it's going to look like a 70's bonnie in no time.

And the tenere carb saga is over. Runs good on all throttle input.
Final days fiddling was to recheck float level which maybe was 2mm high and put the needle on the secondary carb also 1 notch towards lean. Also checked the carb sync that it engaged the secondary carb at the correct throttle input, it did.

So total tally of what actually needed to be done if I’d known what to do:
Both needles 1 notch towards lean, adjust float.

Well, now I know weird Yamaha dual carbs for thumpers and a little about carbs in general.

Then I’m up to 3 working bikes and I can finally start working on my 1989 Kawasaki gt550 and the sidecar.

And the tenere is still a 80s product. The loving main/only fuse blew as soon as I engaged the start motor to fire it up today for the weekend gravel brapp. I rode 60 miles and started it multiple times to check the carb settings yesterday. gently caress error checking electrics after work on a Friday. I tossed the luggage over on my 93 Honda nx250 and parked the tenere for the weekend.

I don't see the benefits. Ignoring the added complexity (this is difficult) why would they do it this way over a single slightly larger carb? Is it cocaine?
