Throttle Problems

HELP!
My 05 V Star 650 Silverado has a very bad stuck throttle after she gets hot. At every stop sign or stop light after downshifting she stays in high RPM. I thought it was my shifting habits since I am a newbie, but while shifting on a good day it still revs. The throttle control recoils correctly but still no change. Any help would be a big help.
Thanks

Is this the same bike you were having problems with in the Yamaha thread?

Check your choke....
If it isn't opened after you start the bike and warm it up a moment....It could cause the motor to run fast at stops.
Otherwise, you might check your idle adjustments.....
Although neither of those would explain why it appears to re-set it self when you shut it off and re-start it
I haven't seen the guy I was going to ask about it...
Take it to a reputable Yamaha dealer....(I know, that's a oxymoron....But if I said it any other way, your confidence level might drop too far to consider do it)
They should be able to nail down an answer...for a fee

Doesn't that bike use a push / pull cable system?? You may very well have a broken cable or even a kinked cable. If it were the choke staying on after the bike warmed up, it would more than likely cause the bike to stumble and die at a stop, not rev up. And you would be trailing a lot of black smoke.

Yeah this is the same bike,
Choke is in, no black smoke, no kinks, and are there any reputable Yamaha dealers?

OK...lets play 20 questions then...
How many miles did the bike have when you got it?
How long did the bike sit before you bought it?
How much gas was in it when you first looked at it?

There is the possibility that your carbs are gummed up from old gas sitting in them......and it doesn't really have to be that terribly old either...It depends on the conditions the bike endured between the last ride and you buying it....Up here in the Arctic north...gas can become pretty unstable over the course of a few months of colder than witches tits weathers.....or from not having the tank topped of...which creates moisture and eventually rust....
Try draining the tank and carbs...
Shut off the gas petcock valve and run the engine until the carbs starve the motor...then remove the fuel line to drain the tank or remove the tank and drain and flush it out to remove any rust or gum....
Next go to an auto parts store...Advanced or Auto Zone is good, and get some Sea Foam...you'll find it with the carb and injector cleaners....
Re-install fuel tank and or fuel line pour in a WHOLE can of Sea Foam...fill with new fresh gas...(I prefer Mid-Range 89 octane but your bike should run fine with Regular 87 octane) open the fuel petcock valve and let the carbs fill.
Let it sit for a few minutes...maybe 10-15, then take it out for a test ride....It might take a few miles to clean the fuel system out of any remaining crud...but if the problem was caused by gum, varnish or other fuel system contaminates...the Sea Foam should clear that up...
Check your private messages...I am send you the addy for a site that might be of interest and hopefully some help to you...
Good Luck

All it would take is one broken strand on the inside cable to cause this problem OR..... Have you lubricated the cable ???

PLEASE, Do Not use WD..... The only thing that stuff is good for is starting fluid....
