Question about 2004 Yamaha V-Max

1 Answer

Vmax engine will not idle without the choke on.

My vmax has been sitting for about 7 months. I had StaBil in the gas. I installed a new battery. The engine starts with choke but when I take the choke off it dies. I drained the old gas, put new gas in and put a new fuel filter on. Still the same.

    I have the same issue with my 2003 VMax. It sat in a garage about 5 months without Sta-bil in the gas. Now it starts fine, and idles okay, but when I put it into gear and start going it stalls out. I had to leave the choke on to keep it from stalling while riding it. I hear Sta-bil needs to be in the gas when it is going to sit for over a month. Also you need to run it for awhile with the Sta-bil in the gas to make sure all the lines have the mixture in them or they will clog...... Have not taken it to get serviced yet and see how much that will cost me...... :(

    2004 Vmax, sat for 5 months, changed oil, plugs, 93 octane refill and drain, fuel stabilizer added, but bike will only start with choke on, fuel pump relay checked OK, carbs disassembled with no build up in jets or lines. Service depart 1 shop wants $580 to go through 4 carbs, another shop will do it for 300. I doesn;t seem that hard, but the shop manual is useless. There is a valve on every carb vertical position with a cap covering it $30 each, that seems to be my last resort,

    Any help

Sounds like your carb. may be gummed up. Did you start the bike and let the carb. get stabilized fuel into it when you parked it?

I have a Craftsman Snow Thrower model # 247.881731. At the end of last year I drained the gas as recommended in the manual, this year I filled it with fresh gas and it now has a problem starting. I pu

Draining the gas from the tank doesn't drain the float bowl in the carburetor. It still had last year's gas in it. Gas will start to turn to varnish if left sitting 6 to 12 months. You'll probably have to remove the carburetor, disassemble it and clean it out with Gumout carb cleaner or some similar product.
When you get it running and the snow's over and done with, put some Stabil in the gas tank to prevent the gas from converting to varnish and then start it up and run it until that stabilized gas is through the carburetor and into the engine. You can leave it with the treated gas in the tank.

Runs on choke,why?

The engine is running on choke because the jets are probably clogged in the carburetors.Some of the newer carburators have very little in the way of adjustment and it is usually cheaper to replace the whole carbthan to try and fix it. Tip : Always use premium gas with no ethanol in any small engine. Ethanol blend gas has ruined more small engines than I can remember. Especially ones that sit for an extended period of time ( like a snow blower). I also recommend add Stabil or Seafoam or any good quality fuel stabilizer to the fuel tank of all small engines. Hope this helps.

Start up after sitting long time

After sitting a long time
1. drain all gas as alchol in gas absorbs water BAD!!!
2 mix new gas + oil correctly and fill tank
3 spray starting fluid in carb.
4 put full choke
5 set throttle
6 pull till engine pops
7 place choke to half choke and pull a few times to start
8 repeat steps 3 to 8 until running

Other problems are bad gas lines
problem with spark

Bottom line the engine should at least burn off the starting fluid
if it continues to stop the carb is going to be cleaned

01 Yamaha V Star won't start without choke. It had been sitting for months so I drained the old gas, refilled with fresh gas and fuel enzyme, and installed a new battery. Please help-just purchased! thanks

choke opens up the jets just a little more to squirt more fuel into the chamber during warm up, meaning YOU NEED TO USE THE CHOKE TO START YOUR BIKE!!!

This sounds like the throttle spindle sticking, or the cable sticking, if you remove the top cover and air filter, then push the throttle spindlefully back to the stop screw with your finger, then try again, the spindle may be a little gummed up.

Will not start, put new gas in it, stabile in gas, new sparkplug, dry gas in gas. Gas left in it over the summer months, so I sprayed some carb cleaner in carb. It just turns over. Drained gas from bulb,...

It is very common for the jets to varnish up (even with StaBil) and carb cleaner can't get into those areas. You can take the carb off and soak it in carb cleaner.
One method that I try before I take it apart is to spray a ONE second blast of starting fluid into the carb throat. Attempt to start the engine. If everything but gas is ok, the engine will start. Do it only one more time, this time with the choke on full and usually this is enough to get the engine running.
Be careful and don't do this more than twice. Starting fluid is very dangerous to use and will ruin your engine if you use more than a one second blast more than two or three times.
Have a fire extinguisher handy if you motor backfires and the carb throws a flame.
