Throttle spring

[SQUIDO]

Can anyone tell me how to lift the tank??i dont have service manual to show me

how.Want to do this mod.

thanks all

Yeah, just unscrew a bunch of screws and pull it off!!!

Okay, let me see if I can walk through this.

>Unscrew the two screws (allen head) at the front of the gas tank down below the handlebars.

>With the seat off, you can see a long bolt at the back of the tank. The tank will hinge up on that, but to do the spring mod, you will have to take that off.

>Take the silver trim off the tank. I'm not sure if it's required or not, but you run a big risk of damaging it if you don't take it off. Be VERY careful. You can see two allen head screws - one on each side, and two black "push fasteners" with what looks like phillips screws in them. Just turn those screws about 1/4 turn till the head pops out (the screw, you idiot - get your mind out of the gutter). Then you just pull those fasteners out. Here is where it gets tricky. At the front of the gas tank, the silver trim just "pops" out. But do this very carefully just at the very front . When you have the fasteners out, and the front "popped" out, you then have to carefully pull that trim piece straight back towards the back of the bike to get it off.

Put a big towel just behind the tank, and move the tank back about six inches on top of the towel. Now you need to lift the front of the tank up high enough to disconnect the two wiring harnesses that go into the bottom of the tank. At this point, I did not have to disconnect the fuel lines. I just moved the tank back far enough to get to the throttle bodies. Just be careful with the tank that you don't scratch anything, and watch you don't damage the fuel lines.

From there I just lifted the back half of the heat shield enough to work under it - I did not remove it. This worked fine for me, but be careful with it.

Hope this covered everything. I'm sure if I missed anything someone else will jump in.

I would add that I first attempted to just lift the heat shield as described above but ended up pulling the fuel lines, removing the tank completely, removing the T-bar, and taking the heat shield all the way off. I felt I was bending it too much by just lifting the back. This took an extra 5 min. but it made it much easier to see the spring.

I too would be amazed if the spring did anything other than jump right back on the hook after unwinding one turn. It happens FAST and you'll think nothing happened until you twist the grip. :yahoo:

Hey thanks guys will try this mod

I think that is really good advice, and probably what I would do next time. Thanks!

I don't want to sound like a dummy, but is one spring removed on #3 throttle body or are the center springs on each throttle body removed? Got the bike apart and not sure at this point. Thanks for any info. PM. <>< :blink:

Just the one. And it's not removed, it's just released from the hook and it spins around and re-attaches automagically (and too fast to see, btw). This just makes it looser.

Let the spring go and not making contact with the tab and have the same situation described eariler. Spring went around but now there is no contact on the tab and the throttle does not return, ie. not enough spring tension so have to try the wire noose trick I guess. Any midgets with small hands available? PM. <><

D'oh! Sorry about that :blink: Are you sure it hadn't already been released once or twice? Mine was so tight it snapped right back on and is still snug on the tab.

I assume you have checked to make sure your grip isn't binding on something. I find it hard to believe the throttle won't return. I did the spring magic on mine. The spring is totally off the tab when the throttle is closed, but there is still plenty of return action. But I do have a Vista Cruise, and I had to re-adjust it, and the grip had to have no contact at all against the edge of the Vista Cruise.

Positive bmwhd, let it go once and the hook is about a quarter inch from the tab. Just got back from the hardware store and got some soft steel wire to try and loop around the shaft on the throttle body and hook the spring end to try and wind it back up. Not easy with this arthritic bod. Wish me luck. PM. <>< :angry2:

Geez This thread is gettin old

P.M. sounds like your spring has be released before, but even if it was missing I don't belive you'd be having the problem that is appearing now. Sounds to me as though your other springs are weak\unwound or something is hanging up somewhere- though I can't suggest where to start regarding repairs.

:jester:

jjsC6, I've been working the throttle and there was slight binding against the housing and I have got return now. Don't have a Vista Cruise but it was touching the housing. There was alot of spring pressure before and maybe just have to get use to it. The spring hook is like I said almost a quarter inch off the tab but there still are two other springs still in use though. I think I will play around some more and probablly run it like it is. Thanks, PM. <><

 

[painman]

Well, after playing around with the throttle the spring now returns to the tab and didn't have to rewind the spring. Strange but now is working fine. Guess the spring just hung up or just had to work in. Working great and now know how to get to the engine to do the TBS next time. The only thing left is just go for a ride. Later and thanks for the help, PM. <><

Thanks folks....I just road the FJR 2000 miles in 3 days......my wrist was killing me....I wish I would have pulled over and let loose that spring.....I just did and what a difference......

Man, I need to do this. 400 miles into my new '06, and my wrist is killing me. It must be the throttle because left wrist is fine.

Sounds like to me we have a lot of limp wristed guys on this site.

 

[DN325Ci]

I just did this mod on my 06, and it was super simple as advertised. But are there some torque values to put this thing back together? I searched but couldn't find the recommended values. I left it apart at the moment. Do you guys know:

T-Bar bolt torque

Long gas tank bolt torque

Two shorty allen bolts at the front of the gas tank torque

Two shorty allen bolts at each side holding the silver gas tank trim on torque

Thanks,

Don

LOL... was just thinking the same thing! (Author's note: I released my spring a long time ago... )

I've been married long enough that I just prefer to save my right wrist muscles for more important things.

What happens if you unwind the spring more than once.

What happens if you unwind the spring more than once.

The minute this happens, your bike's electronics send an subsonic signal to the Yammy corporate helicopters (black) which are constantly circling for just such an occasion, allowing them to triangulate your location, and void any/all warranties left on your bike... :blink:
