Idle isn't adjustable

According to the Yammy service manual, the idle speed of our trusted steeds is not adjustable.

Idle speed can be adjusted, but not necessarily should it be.

Actually, it is adjustable.... mine was adjusted a week ago at the time when I had the valves adjusted, throttle bodies synched and coolant flushed.

Did they really?

Maybe the idle speed changed after the other work you had done, but did they really adjust it? Since the Yamaha service manual says it's not adjustable, how did they do it?

It is

It is adjustable....really....seriously....for real....really, it is....absolutely positive....really. : )

Adjusted were my bike's idle, the throttle, itself, and the throttle bodies (to synch them). But, I agree that the service manual is somewhat vague and isn't at all inclusive of everything that needs to be done. It also takes the long and cumbersome route in accomplishing some of the work & adjustments it lists.

If you'll note in Section 7, Page 7, it shows you the location of the ISC unit (Idle Speed Control unit). Then, in Section 7, Page 11, it even says: "before adjusting the Throttle Position Sensor, THE ENGINE IDLING SPEED should be properly adjusted. If this is ever something you do, remember that our bike needs somewhere between 950-1050 RPM in order to properly lubricate the engine, its (wet) clutch, and to efficiently move the coolant thru the radiator.

Stay well.

Redhawk.

First, if your dealer's mechanic/tech isn't familiar with this, there is NO way I would allow him to do the valve adjustments and throttle body synchs on my bike. Otherwise, they'll end up doing a partial job, leaving a lot to be desired. The idle is to a degree with the synch screws that are used for the purpose of synchronizing the throttle bodies. Afterwards, if the idle still needs adjusting, which is normally should not, there is a special tamper-proof type of screw that is designed specifically for that purpose, one that requires a special tool for accessing it and one a Yammy dealer should have and be familiar with. All of this is spelled out in the mechanic's/technician's manual.

I'm still not quite sure why you're insistent about changing it and it makes almost no sense why this is such an issue with you. If you lower the engine's RPMs at idle, you'll very likely not be happy with the results since it can create more potential problems than you wish to encounter. If it were a carb'd bike, that would be an entirely different issue. But, not with our 1300 with it's FI and specific engine design.

There is nothing more to share here. Rather than continuing to question me about the answers provided, call your dealer. Otherwise, send me an email in order for us not to beat this subject to death here in the forum.

Take care.

HOW is idle adjusted, HOW?

You still haven't answered the question -- HOW IS IDLE SPEED ADJUSTED??

Don't want to be a pain here, but pages 3-6, 3-8, and 7-10 of the Yammy service manual have sections that say the engine idle speed should be adjusted before adjusting other things. And yes, pages 7-6 and 7-7 show the LOCATION of the idle speed control unit. But how do you adjust it? Can you direct me please to the manual page number that tells your Yamaha technician how to adjust idle?

The question is:

Have Vstar 1300 owners stuck their fingers into this project? Probably not. There comes a time when a technician is mighty handy. And there are times when even the finest technician will do this and that and correct the problem without even knowing what the exact problem was. There is a difference between fixing something and fooling around with something. ~ Butch

Idle

Fuel Injected engines all generally idle high, compared to ka-plunk, ka-plunk, ka-plunk of carb'd bikes. Some mistakenly adjust them to be a little too low. You should check your bike to be certain it's idling between 950 and 1,050 RPM. Anything less is not recommended for our motor. It needs those RPMs to properly lubricate the engine/clutch, as well as allow the coolant to do its job.

Be well.

Thx Morg,This is my first FI

Thx Morg,This is my first FI bike and I didnt know that.

1st FI bike

Well, you definitely chose the right one. : )

Be well.
