SOURCE: Vstar 650 classic. only will idle.

hello and welcome
this is a very very commom problem after the cycle has gone over a storage period of anything over a month or so. what has happened is the deteriorated fuel has plugged the idle jet, and possibley other jetting. this is verified by pulling out the choke allows it to run. because this makes of for the loss of fuel the jets are not produceing. so to fix this you will need to remove the carbs and take out the jets and clean them thoroughly with a carb cleaner and possibly a very small gauge wire to break up builup. especially in the pilot jet. unfortunately fuel added carb cleaners dont seem to work for this kind of problem and to fix right they should be disassembled and cleaned thoroughly. thank you.

SOURCE: Won't idle without choke

The pilot jet controls the air/gas fuel mix at idle . If the jet gets plugged up not enough gas gets to the emgine at idle. You will need to remove the carbs and float bowls and clean them, paying special attention to the pilot valve. Count the number of turns to remove the pilot screw and replace the same number of turns then turn counter clockwise 1/2 turn.

A “very helpful” rating for this answer? Thanks!

I would say you have a blocked or damaged jet. I would strip down the carburettor and replace any badly worn jets and clean thoroughly. When refitting the tick over mixture screw , screw it home and back out about 2 1/2 turns. That will be somewhere near it.
Hope that helps.

I need to pull the carbs off my 1995 yamaha fzr600


You need to remove the seat,tank, air filter box and anything else to get to the clamps to remove them. Then clean them and reinstall them have them synchronized.if you are unsure take it to a shop.at the end of the riding season put alot of fuel stabilizer in it and run it over the winter when possible.

My bike hasnt been ridden for a few months, and you need to give it full choke to start and keep it going, it wont idle when the choke is depressed, It is A Vstar 650 Classic


was fuel left in the carburetors when you parked it your metering jets might be slightly clogged with varnish i dont recomend opening them yourself take it to a professional and next time you park it for an extended period of time close the fuel valve and leave the bike running until the carbs run out of gas "the bike will stop running when this happens"

Last time I STARTED MY VSTAR 1100 I CHOKED IT FOR 10 SECONDS ON HIGH THEN MOVED TO MEDIUM CHOKE FOR 4 THEN TOOK OFF AT NO CHOKE. 2 WEEKS LATER. I started up bike Choke on high bike barely wanted to idle...


Sounds like your flooding it out with the choke out. Try the next time you go to start the bike when it's cold with the choke out and when it starts push the choke all the way in and keep it running with the throtle. If it runs better after doing this then your flooding it on start up. Use 1/2 choke to start cold and see what it does. Good Luck

Starting?


pull the choke out fully, start the engine, push choke into halfway if it will still run, let it warm for a min or 2. ride it, it may need choke still for about a mile. but thats trial and error, try pushing it in, you will find out right away if the bike still wants it.
i have an owners manual on this bike if you need a copy e-mail me [email protected]
