'05 Idle Screw Fix

[05 Limited #554]

Mine does it too. 1800 miles and it's at 800 rpm. I just adjusted it like 20 minutes ago, so I'll keep an eye on it.

Hi guys, I want to share my quick fix, a had the same problem too, fix it twice and drop down to 800 rpm  "crap" well, what I did I tuck off the spring and lock the screw with a lock nut, get some nail polish from your wife and brush a bit at the end of the screw, I did that to my busa and no problem since then. Just my 2 cent.

Catch me if you can!

This sounds like a great fix. Where did you find a nut to match the threads on the screw, a local hardware store? I don't know why they put a spring in anyway. Adjusting the idle should be a rare event.

Take the screw out and go to Ace hardwere store, that's were I got mind at, they have alot of bolts and screws, metric, standard ect. Let me know how it turn out.

same problem here.

turn the screw way up and then adjust it down to 1200. my 05 was doing the same thing until I did that.

Yep, I have an 05 at around 1000 miles, and it has never dropped from it's original 1100 rpm. Did you see them apply the locktite? It keeps pistol screws from backing out at very heavy recoil. Hard to believe it won't hold an adjustment screw.

Wonderful idea !!

Take your .44mag revolver loaded up with 325gr. hard cast LBT's on top of a healthy dose of H110 to the shop and show 'em how well the Loctite works ! Say "see guys, it's like this..."

I'll bet you'll get instant service then, eh?

Glad to hear I was not the only one with the idle mystery gremlin in there bike. I went straight back to the dealer today and asked them, and I quote "what the hell did you do to my new bike". I came here for my initial 600 mile service (@ 1000 miles) to have you PROFESSIONALLY service my new 05 Hayabusa ( PAID cash, not financed) and it states on my service print out that you inspected my engine idle. Upon the ride the followed afterwards it dropped to 800 - 900 rpms. and sounded like it was struggling to keep running. I explained that I did some research and found others to have the same problem. I expressed that they should be on the lookout for this problem with 05's and should make sure the screws are set properly. The service manager was quick to have my bike IMMEDIATELY looked at and had the idle screw set to 1200 rpms. Well, riding will tell me if it changes. Hopefully it doesn't. I will keep you posted. Thanks for the posts to allow me to have a credible argument to a prevelant problem. $0 cost to me.

Ride Safe.

I had the same problem with my 05'.  Removed the screw and noticed it was wearing uneven due to the repeated banging against the throttle body stop.  I filed the end of the screw so it was flat, reinstalled it and the proble went away.

I have an 05, with about 1500 miles on it, and it has stayed at 1100 from day one. Just lucky I guess. If it does start to drift, I'll pull the screw out and look at the end. The real problem may be as you describe. The end wears down, the screw becomes shorter and the idle drops.

Maybe changing to a tough steel screw would help if it continues to wear. But then, what is it pushing against. Might start making a hole for itself in soft metal. I would never put red locktite on an adusting screw. You might end up snapping it off trying to adjust it. Sounds like a typical dealership technique though.

My 05 stalls too, few times when shifting from sixth to forth at about 70mph. I am scarred to press the ignition button at that speed so I usually squeeze the clutch in and coast to a shoulder and then restart. She idles at about 900 rpms, seems like that's too low. I'll see if adjusting it to about 1,100 will solve this problem.

 

[PDBusa]

My was set at 900 when I got her. She'd stall at stop signs until cold. Manual states 1150, that's what I set it at. Hasn't moved in over 1500 miles.

 Oh, and no more stalling.

 

[CLYDE05]

For the record: One more '05 'Busa Limited with the same problem at 1200mi, post first dealer service. I'll try the nail polish trick.

Bro. I had the same with my 05 LE, I read one of the post about stalling out and just adjust the screw and I have not had that issue pop up again in 3000 miles later.

I replaced my idle screw with the type where you can adjust the idle without lifting the tank lol. almost all other bikes have them, its like a screw on one end and then there is a long rubber piece that allows you to relocate the idle adjuster to somewhere you can reach it from outside the bike. My bike was idliny at 900 or so when i first got it and ran just fine.. i adjusted the idle and it kept going back down so i did this mod and 2000 miles later no problems.

Mine required frequest adjustments for the first several thousand miles. Then one time, I adjusted it way higher than the spec and brought it back to spec and it's stayed put for quite a while. I think that spring tension theory is the ticket. Unless the screw is turned far enough to turn the spring as well, the spring wants to "unwind" back to where both ends of it were, taking the screw with it.

I guess it's true for 600 mile service most dealers just charge 160 dollars and just do oil change and give you back the bike.

BUnch of thieves.

I guess I'll do mine myself, I passed college chemistry and mathematics, I can do this. RAWR.

 

[Sloto200]

No problems with my 05 that i bought back in July ...i have 1800+ miles on it now and still idles at 1100 rpms...

 

[mat_rock]

Just to check...

The idle screw, the one where we need not lift the tank, anyone knows what other makes/models that can fit onto the 07 Busa.

Need to know my options.
Thanks.
