Question about 2007 Yamaha V Star Custom

1 Answer

When I first start my 2007 V-Star 650, I have to choke it. I found that if I pull the choke all the way out, it runs like **** for the first mile or so. So I started pulling it out just a little until it warmed up a bit. That seemed to help a little, but it still runs rough & sputters with reduced power when first hitting the road. After about a mile, it smooths out & runs fine. It's really inconsistent & starting to drive me crazy! Any suggestions?

    Can you use gas treatment to clean the carb in a motorcycle? What about spraying carb cleaner in it? We've already had the carb apart and cleaned the jets

Diagnosing issues like this can be hard,, but, I would replace the spark plug(s) and see if it helps.. just because it looks good, doesn't mean its not fouled..Try this and reply to me...

Yamaha TW 200 starts but won't run.

If the bike has sat for a long period of time without being run - the gas that is sitting in the carb(s) will shellac.. Then the carb(s) would need to be cleaned and "rebuilt"..

My 2006 yamaha v star 650 will run with choke on but will not rev . the engine will not run at all with the choke closed . if you cover the air intake it will rev

You have a vacumm hose loose look for small hose no connecter to anything - should solve it - I had a similar problem with a ZX9r the other day - same would run fine on choke not idle or start without it

Good Luck

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
