HOW DO I REMOVE A GAS TANK ON A YAMAHA XVS 650

SOURCE: i have a yamaha dragstar

If it has been sitting for a while I strongly recommend you remove the carburetors and clean them thoroughly, you will need to make sure you remove all the jets, especially the pilot jets because that is the smallest jet in the carb that will plug and it is often the one that will prevent the engine from starting.
Try using some WD40 in the back of the carbs when you try to start it after you clean the carbs. I don't like to recommend starting fluid because it is volatile and can easily catch on fire if the engine backfires.
I'd also recommend replacing the spark plugs as well. Make sure you have good fire. (turn the motor over with the plugs out and grounded on the head to make sure you can see the spark)
I also recommend pouring a small amount of Marvel Mystry oil down each spark plug hole to help "reseal" the rings. Remember that sitting is not your friend and you may have to get the rings back to life by using the special oil.
Just remember you need three basic elements to make an engine run:

1. Air
2. Fuel
3. Spark

Hi there fellow XVS dragstar owner!

I had the same problem before. It is usually caused by the wrong jets installed. have it Replaced with the standard jets that came with it... this will solve the problem on acceleration. Make sure the fuel and air mixture knob is set to 2.5 turns-out from full close. clean the spark plugs.. better, replace it with a new one to ensure clean burning of fuel. also, use unleaded gas. this burns better.

hope this helps

SOURCE: will a gas tank fit from a 1995 yamaha to my 1990 yamaha

no unless you want to modify it to fit which will require a lot of work

SOURCE: I have a yamaha vstar xvs 650. there is a noise in

Try tapping the spokes, if one is loose you'll know it. Check the oil in your driveshaft head.
Picking the Star up to get the wheel off the ground is a chore but you (and a few strong friends) might have to do just that to investigate the noise more fully. With the wheel in the air you can wiggle and listen.
BTW, are you sure it isn't the rear caliper?
