I read Ricksters 1000th indepth post on this topic for a GEN II. Does anyone know if the GEN I is similar/ same concept? I really need to reduce the tension on the throttle. I bought my bike Saturday and hand is cramping something fierce.

Thanks,

Dan

same on my 05, lifted it, it unwound one revolution and caught again. Made a noticeable difference.

 
I did the TSR on my 06 yesterday and it is like a new bike. I've got a 750 mile ride this weekend and wanted to do anything I could to make it long distance happy. I've got grip puppies, a Breakaway throttle lockand a new CeeBailey windshield on the way. I thinbk I'm ready to roll!

I guess sometimes you just have dig in with out knowing all the facts. I just did my TSR. It took about 25 minutes total. Most of that was me taking my time and trying not to screw something up. Much better now. I can hold the throttle by just resting my palm on the grip. Still has good return. If you find Ricksters 1000th post about the TSR, a 05 is very similar, except the gas tank removal. Basically:

remove the 2 bolts securing the top of the tank

remove the front seat

there are two black side skirts on the bottom rear of the tank:

remove the allen screw, one one each side of the tank

remove the plastic rivit, one one each side of the tank

gently pull the side skirt to pop the last rubber retainer

I removed the long bolt at the rear of the tank and slid (picked up and set down gentley) the tank back about three inches (I had a half tank of gas and didn't want to spill it by raising the tank to high) this raised the front of the tank enough to see the throttle spring. you will need some blue locktite

reach in with a screw driver and move the spring hook off of the catch, sure enough, it will realease one revolution and recatch.

I also found all the adjustments and cap locations for the TBS, now I need to just find out where to get one of those fancy measuring devices.

 
I was getting wicked wrist pains, released the center spring and it made a big difference. Changed my grip, so I'm not always leaning on my wrist and it helped a bit more - not much. For highway (only) I added a throttle rocker and it has helped massively, but comes off if I'm not just commuting.

Can one of the mechanically minded out there tell me if the '07 is basically built the same way so that I can get the middle spring released as described above?

Hi ,

Yes its the same and the throttle spring mod is very simple to do,do a search and you will find it shown in photographic form, step by step.

 
Count me in as one of the spring-release converted for the '05 - that one mod made a huge difference to me - wrist pain gone, mid-back-shoulder "pinch" gone....me happy... :D

Thank you to everyone who has contributed to this thread. I was really concerned I was the only one with early onset arthritis. So, I am getting ready to do this fix, and have the following question - since I am already going to have the thing opened up is there any reason not to unwind each spring (3?) one revolution instead of just the middle spring? While I understand that just doing the middle one seems to bring relief, three might be better than one unless there is some technical reason not to do so. Thanking you in advance for your reply. This is an '07 AE.

 
I ended up releasing the wrong spring (my bad :( ), then ending up with slop and a non-returning throttle. I eventually cut out the center spring and put in an after-market, straight spring. I had to drill a hole in the little bracket that holds the throttle cables to thread one end of the universal spring thru'. It's very linear and smooth, now. And it's still not as tight/stiff as the OEM set up.

Certainly beat the hell out of pulling the entire throttle body and re-wrapping the coiled springs.

Captain, you do not want to undo all 3 springs on the throttle bodies. Believe me you need the other 2 springs to actuate the shaft that contols the units. One spring undone will be sufficient to relieve the excess spring tension so you have to have the other 2 springs to operate the shaft to the return position. I have heard of someone I believe who did 2 springs but never heard of the outcome. Hope this helped. PM. <>< ;)

 
I used Rickster's instructions (which were a great help) to relieve the tension on my 07's ridiculously stiff throttle. After reducing the tension it is very much like the throttle on my 05, which I don't find to be bad at all.

I never ride without a using a throttle rocker. It gives me better fine control of the throttle and allows me to relax my grip, which reduces fatigue and strain on my right wrist and hand.

 
One more time, let me thank everyone who has contributed to this post - especially Rickster and Painman. I hope any non-mechanics get this far in the post to read this, 'cause this is written especially for you. I did the thottle spring release this AM, and am a much happier camper. As you can see in the ID block I have an '07 AE. What you can't see is that I am 63 years old, and never road a motorcycle until I was 60. In fact, my first bike was my 60th birthday present to myself. While I am not w/o a brain, I have generally stayed away from taking large mechanical things apart to fix them, like cars and motorcycles. Not because I didn't want to necessarily, it just wasn't part of my "growing up" experience. At the young age of 63 I realize I missed out on a lot - especially the art of motorcycle mechanics. Anyway, all this is simply my way of saying that if I could do this - anyone can. I do, however, wish to add a few notes based on my experience with this mod.

1) First and foremost - I downloaded Ricksters 1K post w/pics, and saved it as a PDF file on my computer. I also printed out the instructions. My original intent was to have the computer in the garage with me so I could see the excellent pics Rick provides in color, but this ended up to not be necessary.

2) The basic tool kit that comes with the bike has a 4mm hex driver, which works for the first step in the process, but not a 6mm which you need for the gas tank screws.

3) Also, please note that you will need a torque wrench when you put everything back together. Best to get one before starting. I had to purchase a metric hex head set for by socket drive set, torque wrench, "loktight", and hemostats (which I ended up not using) - see below. You will also need a metric driver set (mine was a 3/8" driver but 1/2" would also work fine).

4) Follow Ricksters steps just as he has them laid out.

5) I found that I needed two lengths of wood to hold up the gas tank. One relatively short one to get it started, but enough to enable me to get to the electic release points. And then a longer one that enabled me to work fairly freely under the tank to get the rest of the stuff out. Like Rick, I also used a bungee to help hold up the tank. This proved especially helpful as I was putting things back together.

6) For me the hardest thing was just finding the spring and tang. While Rick's pics are exact it's not the same as looking at the real thing. Once I located it (by moving the throttle a bit) my first reaction was, "OK, now how do I get to it?" Oh, yes, I highly recommend having a flashlight at this point.

7) For me, I just couldn't see how I was going to get my hemostat in there, but I was also at a disadvantage in that the hemostats that I got at the hardware store were too big for the job. If I did this again I might try getting them at a medical supply store. But, in the end I didn't need them.

8) I had some needle-nose pliars, and so maneuvered flash light and pliars to get to the spring. BTW, I found that each time I stepped away from the bike to get something else, I had to reaquire the location of the spring.

9) I couldn't really see what the pliars were doing once I got them in the vacinity because it was just too tight down there, so I went by feel. It felt like I had the spring, I moved the pliars, and heard a "sspprrrinnggg" sound. But it didn't feel like the pliars had let go of anything. Now my question was, "Did the spring unwind because I pushed the pliars against it, and thus pushed it off the tang or did the spring simply just pop off the pliars without going anywhere?"

10) I did not want to presume that the spring had unwound because I really didn't want to put everything back together, and then find out that I had to go back in there. Not that it was difficult - just a pita. So I grabbed a screwdriver. This tool worked ok for someone else on this post, and now that I had a much better idea of where the spring and tang were I figured this would go easily. I was bit nervous about the potential of unwinding the spring 2 turns instead of one, but not overly so having read all the other inputs to this process from other folks. Got the screwdriver head in the right spot, and "sspprrrinnngg" - the exact same sound. Now I was just about positive that I had unwound it twice.

11) So the next trick was to put everything back together and go for ride. The only issue going back was the plastic rivet holding the back of the heat shield down. This was a pain to get back in, and it never satisfactorily did so. I satisfied myself that the T-bar was going in and the gas tank would come down - all of which should hold the heat shield in place w/o any problems.

12) Everything went smoothly on the "rebuild".

To end - if you have gotten this far in the post, and the throttle spring is an issue for you - do this now. Don't wait. It took me a bit more that 30 minutes - probably 45 from start to finish - but remember what I said on my intro above. I took my time to get the right length of wood, re-reading Rick's post (I had a hard copy), etc. I was just relieved that it didn't take me 2 hours, and I didn't muck something up so badly that I couldn't even get it back on the road. The ride proved the point of all of this. What a relief! I still want to do the G2 throttle mod, and for ergos I will raise the handle bars. But, these are not as critical now, they can come later.

No, I haven't become a crazed, self-rightous mechanic, but I certainly feel good about taking this on. Again, thank you one and all for all the information, support, etc. What a great group to be a part of! BTW 110 did not hurt at all.

 
I never thought the spring tension was anything but perfect on my 05. Seems like I'm the only one on the forum to think so. After reading all the spring release threads for the last two years and how happy the owners now were, after this thread, I just had to try it.

I had the tank up anyway to do some wiring, so what the heck.

My biggest concern was the it would unwind completely and lose too much tension. That turned out to not be a problem, I was surprised how weak the spring actually is. I simply reached in with a fairly long flat blade screwdriver and lifted the spring hook off its seat. It spun one revolution and caught on its tang. Couldn't be easier.

I'm wondering if its not too easy now, but I think it's just a matter of getting used to the lighter throttle.

Glad you got it done Captain B. I've heard of some that even removed the middle spring with very similar good effect. If you do the G2 throttle sleve combined with the spring mod you'll be smooth as glass in the twisties. And isn't that where all the fun is at? Good on ya and ride safe. PM. <>< :D

I think the throttle on my 05 is fine just as it is. The tension on my 07, however, was horrible.
