Question about 1979 Yamaha XS 650 F

1 Answer

It's a '79 model. I've stared at it and gulped. I've had it since '82 and had carb problems ever since; I've rebuilt it once in '05-'06. It started leaking 1)out of the bowl and 2)into the cylinder and crankcase after it fell over off its sidestand in early '07. I'm fed up with taking it apart.

    I had a similar problem on my 93 GSXR 750 which was carbureted. When you rebuilt the carb did you check the float adjustment if it was correct or too high?

    Thanks for replying. That idiotic FixYa site makes you think you owe money for asking a question, so I'd given up on getting an answer. The bike ran fine for about 1 1/2 years between rebuilding and when it fell over. So I would say that the needle was properly adjusted. But since these carbs are Mikuni BS38 CV's, and that you've probably not seen them before, or at least not installed on THIS (since you have a Suzuki) bike my original complete question that asked if anyone knew how to reseat the float without taking the carbs out is probably moot.

Echo HC-150 rebuilt the carb, and now the primer bulb sticks and engine won't start


Try to pressure test the carb to see if you have an internal leak. If it won't hold pressure then it is junk and needs to be replaced. If it holds then double check that you didn't accidently put the gaskets and diaphragm in wrong. If it holds and still doesn't work right replace the carb anyway. They are relatively inexpensive

I recently got a 74 sportster 1000 reverse controlls. sat in a garage for 20 years bike not ridin bike is complete. Im mechanically inclined but not very good with bikes. So my terms an wording is probly...


Dustin:
Your terminology is off a bit but I'm trying to figure out what you say you have done. To start, the coil off the 82 model is the wrong coil for your bike. Your bike has a points type ignition and requires a coil with a primary resistance of 5-6 ohms where the 82 model coil is for an electronic ignition with a primary resistance of 2-4 ohms. If you know how to check the resistance of the primary windings on the coil, check and see what you've got.

But, if you had the bike running and after you put everything back together, you evidently shorted out the points. Use a test light and check for power to the coil. If you have power to the coil, check the black wire coming from the right side of the coil down to the timing cavity. Take the plate back off the timing cavity and see if anything is grounded that shouldn't be. Use the starter to spin the engine over and make sure the points are opening and closing.

Good Luck

Engine revs to full throttle when starting 1100 Yamaha maxim


More likely too much air - runaway revs is indicative of too lean, not too rich. Regardless, it is your carbs causing the problem - strip them down and look - for peace of mind on an 82 bike, I would throw a rebuild kit at them.
