High idle after using some injector cleaner

[fazil]

Hello friends, after a long time,

Last week i put some Liqui Moly injector cleaner to my 2005 Fz6 and gone for a pretty long ride like 150km.
Then after coming back home, i realised that idle was a little bit higher than normal. Like 1500Rpm instead of 1300.

I tried to adjust it from idle screw and turned it all the way out, but no respond. Still the same.
May be while making the thtotle body sync. i used all the tolerance of the air screws. I'm not sure about it.
I don't have a sync tool at hand. May be i can try to turn off all the air screws like 1 turn all together to make the idle screw functional again.
What do you think?

Try turning the "base screw" out one full turn, then sync..

Dunno how successful you'll be W/O a sync tool..

Thanks Scott. I did it today.
Now the idle is around 1250 Rpm again after some air screw adjustments.
No syncronization anymore but sounds better.
I made my own tool last year but the height of the hoses were not enough. It looks like they should be at least 1.5- 2 meters to work properly.
May be i can try that again soon..,

By the way, i have a spare throttle body laying around.
May be also i can try to put it on.
Meanwhile i can clean the injectors one by one may be...

Do you use injector cleaner etc?

Greetings....

Well, if it's idling again, I don't see a reason to swap TB's

I'd concentrate more on getting / making a sync tool. You need to get those
adjusted properly.:



As for injection cleaner, I've never had mine out but do use Yamaha's Ring Free additive:

https://www.amazon.com/Yamaha-Yamalube-ACC-RNGFR-PL-12-Ring-Additive/dp/B002GU4SN2?th=1

I run this in EVERY gas powered machine I own as well as my customers (small engine repair)
machines.. It does actually work and well worth it in preventive maintenance.

Now my bike is run 365 days a year, I have the idle set for 1,000 RPMs (smoother idle IMO).

I OFTEN see improvement in say 2 stroke weed eaters, highest RPM's I can get-
initially fixed. Let it sit over night, I can tune (with a tach), noticeably more RPMs out of the
engine.

Do you use that injector cleaner regularly or once in a year or so? Do you feel difference in idle Rpm after using it?
I haven't used it for a long time and it affected idle. May be some stuck holes are cleaner now, who knows...
1000Rpm is very nice if it's smooth. I can try to adjust mine to 1000 also next time.
But first i should make a valve adjustment may be. I've never done it.
Bike is like 45k km's and 20 years old.

Here's an old video I made for showing charging purposes, but you can see and hear the idle.
18,000 miles with ^^ video. Currently at 38,000 miles and just as smooth running

Ring Free is ALWAYS in the bike (and everything else I own).
You can do a shock treatment with it. Much cheaper than sending them out /
down time, etc, if it works. Again, preventative maintenance.

It took me much digging but for shock treatment, it takes 2 OZ per gallon,
not 1 oz per 10 gallons

I'll do the same about idle after i see this video.
By the way, did you ever check valve clearances or change cam chain or tensioner so far?
I have a spare cam chain and tensioner waiting to be installed also.

 

[TownsendsFJR1300]

I checked and adjusted the clearances and found one exhaust valve .001" too tight.
Not much at all out of spec but I was there and figured get it to spec. That was at
26,600 miles(almost exactly). Still has the original chain and tensioner to date (no noises)

 

[TownsendsFJR1300]

If you have a new chain and tensioner on hand, I would put it in while there.

Better there than collecting dust!

Cleanest bike i've ever seen...

 

[fazil]

You're right.
I'll do.
Also i'll check valves.
