Got an 81 XL-500s yesterday for $1700. It rides but stumbles past 3/4 throttle. Hoping doing what you did in this video fixes it so I can really open her up on the road.

There’s a small rubber O-ring where the needle goes in the carb (where the fuel comes in). Be careful it doesn’t come out if you blow compressed air in it.

Can’t get gas to squirt out at the end, any idea what I did wrong or what I should look for? Great video btw, was very helpful.

Checkout the video at 11:00mins. Were the holes in the membrane good? Does the Accelerator pump shaft move when you twist the throttle?

@PSanguankeo Жыл бұрын

I have the exact same carb. Can’t find pilot jet anywhere on it. Does it have one? Thanks for the video!

@WeekendHobbyMechanic Жыл бұрын

Check at 10mins into the video. There’s a small rubber o-ring, spring and then the adjustment screw.

I have a 1982 xl500r and want to swap in a mikuni carb. Any idea what the best size and jetting would be?

Don’t know off hand. I put a 1979 XR500 carb (and intake boot) on my XL500s. 2mm bigger.

@RemiDean-dm4pk 2 ай бұрын

Would this be the same procedure on 1981 xr500? Seems to look like the same carb

Same.

Hey do you think you need that little rubber boot for the accelerator pump rod ?

@WeekendHobbyMechanic 3 жыл бұрын

That rubber boot needs to be in good shape, the pump won’t work if it’s deformed.
