Holy Smokes! New Throttle Cables.

Just finished stripping my '03 LT down and installed the new style throttle cables. Geez, what a difference! Feels like a light bike now. No kidding.

I put 17,000 miles on this machine since I bought it in April 2007, stiff throttle is all I knew. It was okay, the throttle boss and cruise control helped, but after developing persistent pain in my right hand I decided to go for the upgrade. I spent a few hours researching here and ordered the suckers. Two cables and the repair kit cost under $150.

I stripped the bike down, changed them out, and changed the filters, fluids and plugs while she was nekkid. Found it was real easy when installing the throttle ends first then working my way to the handle bar end of the deal. And I didn't have to remove the fuel rail or air box to git 'er done.

I thought cutting the "Brown Wire" was a big difference, but this is just sick! Glad I installed that back rest a couple of months ago.

This is a must do pre-2005 owners, a must do!

Did the same on my '01. Huge difference, and unlike what the manual says, I didn't have to remove the fuel rail either.

My wife is into beading, and has some long hemostats (fer those of you in the hills, thems' like long nosed pliers fer docters) - snaked the cabled right in.

My Mrs used to like how the bike rolled on the power "Nice and slow" - not once I had changed the cables!!!

Cables?

I'm surprised to hear cables make such a difference. I bought my '03 last November in NC and rode her back to Texas(1400 mi). If I hadn't had cruise control, my wrist would have been in bad shape. Tough twist grip on this thing! I followed advice from a thread I found here and wrapped the grips in a gel-filled tennis racket handle wrap. Made a BIG difference. The grips are smaller in diameter than any I am used to. Causes the old arthritus to kick in. The addititional size helps in leverage, I think.

I did the same thing...Wilson handlegrips . I figured it was good enough for now. Is there no way to lube the throttle cables or is it just easier to replace them?

Replace them - you won't regret it.
Remember you need to cut a small hole in the lower handlebat fairing to route them right (or buy the 05 fairing bit)

OR Save yourself $150

Following the advice of another BMWLT member I disconnected 1 of the 3 return springs at the throttle body intake. This has the same effect and the original cable has got to last longer. Also apply a lot of lubricant to the 90 degree turn under the grip just before the inner cable enters the outer. Check to make sure the throttle closes all the way before replacing the tupperware. It works.

Hmmmmm
Not too sure about disconnected return springs. The problem is with stiff cables, so I would have thought they would eventually get stuck - not nice

I know it's a lot of work, but you guys are missing out on some real fun if you don't install the upgraded cables. If I were BMW I would do it on everyone of them for free - gain customers for life.

I swear, the thing zips like a Hayabusa now! Don't cheat yourself... change 'em.

I beat that horse to death so I'll shut up. But the difference is just NUTS! Shut up Ed.

Here are the BMW part numbers for the stuff you need. FYI, there was another set of cables that came out in 2003 to address the issue (it used the existing throttle grip cable guides). You DO NOT want these. Get the P/N's below for the 2005 style cables and kit. You MUST buy all three parts, prices are approximate. I ordered mine through Gulf Coast BMW in Houston.

Throttle Close Cable: #32737694490 ($45)
Throttle Open Cable: #32737694491 ($59)
Repair Kit: #32727691990 ($26) (You MUST buy this repair kit because it allows new style cables to connect to throttle grip)

Lots of good instructions on the forum, just seach "throttle cable replacement" and you can research for hours. You'll find instructions, tips, pics and bulletins.

And here's a tip from me: The new cables exit the throttle in big sweeping-radius guide tubes. This drops the cables an inch or two below the grip. This necessitates making an opening in the bottom plastic handlebar cover so the new cables can enter there. BMW sells a new plastic cover but, and here's the tip, you can cut the access hole yourself with a Dremell tool and save your money. Instructions for making that hole are in BMWLT somewhere. Good luck to you.

Replace them before they break

I had heard stories about the old style cables (pre- '04 or '05?) being stiff, and breaking.

I changed mine, just by shear LUCK and coincidence. I was doing the 24K maintenance, and just was ready to start putting tupperware back on. A little voice in the back of my head said, "Check to make sure she'll start, before you put all that plastic back on!" For once I listened to that little voice.

Started her up, and she idled just fine. Gave her a little goose on the throttle, and SNAP!

All I had to do at that point was take off the air box. Manual says take off fuel rail, but I was able to use hemostats to snake new cable in place. Man what a difference the new ones make.

As a bonus, I wasn't stranded on the side of the road.

Are these numbers good for a 2000 LT also? I'd love to do this prior to BIke Week. I'll see if I can work in the time. What do you guys think, 4-6hrs?

Re: Holy Smokes! New Throttle Cables.

I was really interested in the LT when it was first introduced. I demo'd the bike at the Honda Hoot in Asheville that year. I'm not sure the dealers had them yet. After the ride, the BMW guy asked what I thought of the LT. The first comment out of my mouth was that it had the stiffest throttle of any bike I had ever ridden. I eventually bought a used '99 and while it is a great bike, the throttle was always tough.

I installed the new style cables on my '99 about two weeks ago. Bought them from my local dealer, Touring Sport BMW. The parts manager made sure to mention that the bar cover had been changed; he said, "I could sell you a new bar cover, but you could just cut a hole in the old one." Of course, I had read that on the site already but that's great service. I had looked at photos of the new style bar cover but while I was at the dealership I examined a new LT on the floor to make sure I knew where to carve the hole with my Dremel tool.

My friends in the North (North Carolina, that is, but we generally don't hold that against them) helped with the installation. Like others have said, we did not remove the fuel rail. Took a little monkeying around with needlenose pliers and a hemostat to coax the circlip off the end of the top cable. Once that was done, the rest of it went pretty smoothly. We did not disconnect the throttle return springs. We did find lots of crud on the end of my bar that was binding the grip somewhat; we cleaned it up and squirted in some WD-40, which smoothed it up.

The trip back home was primarily Interstate; I noticed a difference in the throttle but with holding speeds pretty constant I didn't have much chance to appreciate the difference.

I rode the bike to work today and took back roads. It really made the bike much easier to ride. Maybe now my cruise control will get a break. Looking forward to more riding in the Spring. I'm pretending it's a 2005 model now.

It's been my observation that mods and farkels that cost about a hundred bucks seem to be the ones I really enjoy. So far that category includes HID low beam, LED saddlebag light conversion, and new throttle cables. All are winners.

I was wondering how that was working for you. Glad it made a difference. It is a fiddly procedure though.

You wouldn't have guessed from the prior posts on the subject, though. Thanks again. Maybe the second time is easier than the first??

It's the same part numbers for all years. What your doing is putting on the throttle cables from the '06 and newer LTs, IIRC.

Re: Holy Smokes! New Throttle Cables.

The part that was "fiddly" was getting to the circlip that anchors the upper cable; we had difficulty fitting tool in there to get a purchase.

John and Rando: Do you think it would be possible to just cut the fitting on the old cable, and pull it out from the inside? That way you could easily remove the circlip from the cut piece?

Obviously it ruins the old cable so that you couldn't re-use it, but that's no loss; I threw mine away.

Yea I think so. I was just a little worried about, with time constraints, causing more work if it didn't work out and somehow had to reuse the existing cable.

Using Randy's pick method of removing the clip worked great. Just don't tell anyone we didn't remove the airbox or they'll line up at the door
