SOURCE: 1989 virago wont get rpms up after start

is it just out of winter storeage? could be gum in the carbs, get some fuel system cleaner additive and put it in the gas. run it on idle and get it hot, leave to stand overnight and try again. you are not getting enough gas and when you open it up you are giving more air but not getting enough gas. try changing fuel filter too.

Sounds like it may be drawing air around the intake somewhere. Let it idle and spray around carefully with wd-40 until it speeds up. This will reveal the leak.

SOURCE: Virago Red Glowing Pipes

you can add fuel stabalizer to prevent carbs from gumming, get the fuel down low in the tank add stabilzer and add fuel so it mixes now run the bike for a few mins to get the carbs lubricated and you good. the noise could be the valve train from cold oil etc hard to say. as for your red pipes
Most likely cause is that you are running lean (not enough fuel/too much air). This could be caused by the wrong size jets, but if you have not changed them, I would look elsewhere. A clogged fuel filter could be to blame. That would be the first place to look. Next I would look for a leak around the joint from the carb to the engine the rubber joint there get brittle over the years and are not air tight anymore . Spray starting fluid...or WD-40 around the joints and listen for a change in engine RPM. This would indicate a leak, You might just have to rebuild the carbs.. good luck

I'll tell you why. It is cold natured. I have a 89' Virago, and it doesn't like going anywhere till' it is warmed up. I usually just set the choke up a bit for about 5 minutes, and then hop on and go.

1994 virago 1100. Starter spins but wont turnover motor.

Hi, Manuelverdin the starter drive/Bendix/clutch is a mechanical gear driven component that engages the clutch pack ring gear to turn over the engine. It has an internal mechanism that allows the gear to turn in one direction and once the engine starts allows the drive gear to free spin. If gear free spins in both directions then the drive gear has failed, it is not serviceable and needs to be replaced.

I have a 1988 honda shadow 1100,Ijust bought a new battery and it is charged up,go to start it it wont start until i hook cables from my car and then it starts right up..It does crank over without car...

Hmm, this can be starter brushes. Engine needs lot of electric power for starter and plugs. If starter is bad, it takes all power and nothing left for plugs and you can"t start the bike.

I just bought a 1988 yamaha virago 750 and it was stored outside covered for over 4 yrs.Cleaned carbs and gas tank,put new plugs in,new fuel lines and checked fuel filter is ok. I have spark,compression...

good start on cleaning things BUT, you should replace pump. the pump will have the same gum **** the tank did. you can unhook lines and turn over to see how much fuel you get

If you are certrain there is power going into the coils and there is NO spark (remove a plug, ground it, with the ignition on, press the start button - observe there is NO spark at the plug) replace the coils.

Have no power on acceleration, backfires 4.0L Jeep

could it be your throttle sensor? If it is a carbureted engine, check the accelerator pump inside the carb.

I have a 1985 xv700 virago. one of my plugs are misfiring. I had issues with my original one. yamaha dealer told me i needed a new cdi box. He sold me a used cdi igniter box from a non running 1985 Yamaha...

follow the plug wire back to the coil and see if there are any breaks, if not might switch coil with the other one and see if the other plug now misfires, if so replace the coil, most cdi problems are not intermittent, typically they either work, or they dont.
