The needle valve may be stuck open or there is a bit of grit/varnish flake keeping it from sealing completely.

Take the carb apart and clean it.
A soft pencil eraser works well for cleaning the seat.
Make sure to blow it out real good after.

for reference, the needle is attached to the float. the needle sits into the seat. follow the float to the needle, remove float and the needle will come with it. careful removing the float pin, you dont want to damage the towers that it rides in. on your sled, and if i am incorrect hopefully someone will correct me, there should be a phillips screw with a flat washer securing the seat. you may have to use some smooth jawed needle nose pliers to get the seat out.

be careful not to damage the seat. you dont really have to remove it at this point, but it makes for easier cleaning. check for crud, debris, or anything out of the norm. clean it out, reassemble, and test on the bench. with the carb upside down, this will be equivalent to the bowl being full and you shouldnt be able to blow through the fuel inlet with your mouth. if you can blow through, your needle isnt sealing to the seat.

Hey guys! I was wanting to do some fine tuning on my sled. Like just adjustments as far as I'm concerned cause All my liquids and sparks are new. They have some stock adjustments on the hood. my carb is all adjusted. I was mainly thinking about the suspension and front shocks on the ski's. I'm not the guy for that. Any suggestions on what to do there for better riding?

its kind of a change and see what happens vs a set it and forget it when it comes to tuning the suspension. first and foremost, make notes (i mean write the stuff down) of where things are set at before making any changes. secondly, make one adjustment at a time and then test to find results.

off the top of my head, and i can do some further research, your sled will have limiter straps in the front and possibly in the rear of the skid. your shocks may be adjustable as well. i am referring the the skid, not the ski shocks. again, in the skid, you may have optional mounting holes for the pivot arms. with the limiter straps, you will have optional mounting holes. depending on what you want to achieve will lead you in the right direction. softer ride, firmer ride, more traction, more steering, less steering can all be adjusted within the skid.

on the struts, you can adjust the preload to a certain extent and change the handling as well.

Hey again. I lost my key and I want to get some more riding in before the season is over. Is there a way to start my Yamaha XLV 540 without a key?

try unplugging the wiring connector to the key switch and pulling on the rope.

You can replace those switches.

to bad your kill switch doesnt work, that was your way off. i have no first hand experience with electric start sleds and bypassing the key switch but i have ran several without e-start and saw no issues.

you may be able to have a locksmith cut a new key, you can find a used one, or may still be available new. many models will interchange, dont limit yourself to just the xl-v. i may even have some around that will fit. i can look if your interested.

whats wrong with the kill switch? you could always wire in a safety tether or an aftermarket kill switch.

I found my key. But thanks anyway. To turn it off I just plugged back the ignition wires. I don't know if that is bad for it but it worked... I'm guessing the kill switch works I just don't have the button for it.
