Hey my names Josh and I'm new on here with not much mechanical expirence. I have a serious problem with getting my 2006 yamaha v star to start after sitting for 8 or more hours. Only way to get it to start is to remove air-filter and spray some starting fluid to get it going. Will start immediately after doing that. Once started it will crank every time on first crank and run perfectly reset of the day. Once I park it for the night and it sits for 8 hours or more. The vicious cycle of trying to start the bike happens again. I live in SC so I have warm weather now. Dosent matter if its 90 or 32 outside same thing.

History

Bike sat for a period of a couple years. Had new tank put on, Carbs taken off and cleaned 3 times. New spark plugs and wires, new battery, new boots going from carbs to motor, new fuel filter and gas lines. I am able to disconnect gas line turn key on and try to start. Gas will pump out of line. I have taken plugs out and tested for spark. Spark is nice and blue. Have no idea what to do next to figure out starting problem.
what's your idle set at
Okay, dumb question here, are you pulling the choke to start it?

Also, put the bike in neutral, turn the key on, and let it sit for about 30 seconds before cranking.

try pulling a plug after a no start to see if it wet or dry, if dry chock choke circuit pluged maybe.they should be wet after a full choke no start. if plugs look good could be electrical, but that's unlikely. is eng light on. if so bad tps switch. also you can ohms test the pick up coil. they can act real funky at times. when they go bad. don't pull the choke more than 3/4 sometimes full is to much.at least on my 650 in warm weather full is to much. causes stumbling. those plugs should be wet after a full choke no start.

Thanks for the replies. Idle is set to moderate I suppose. It seems to run good well after it does crank.

No engine lights are on.

Pulled plugs after no start and they seem to be wet. This is one more thing I noticed is that after it ran the day before and sat over night. I came out that morning to try cranking and the very first time I hit the start button it fires off for about two seconds and then dies. Thats when the hard starting begins. Its like it burning off any fuel thats in the carbs.

I will try turning the key on and letting it sit for 30 seconds before starting next time to see if that helps.

Hello, I was wondering if you ever solved the starting problem? My 2005 VStar 650 Classic is doing the same thing. Sometimes it will go ahead and start if I don't choke it at all. Thanks

where in SC?. I live here too. I worked at a bike dealership for some time, and ill tell ya, Ive done more fuel system cleans than I could count. It doesnt take long for the carbs to get nasty from sitting. ive had people come in and say they cleaned the carbs and swear the problem is something else. The reality is, is that most people dont know how to properly clean the carbs. there are jet passages that are easily missed by a novice. hard starts if its fuel related are almost always idle jets or air jets.

Dunnsk - Hi there, did you ever figured out your issue. I have the same identical problem as described in this thread. I own an 01 VStar 650.

Thanks,
