throttle tension

I have just purchased a 2002 K1200LT with 9K on it. The throttle tension seems excessive for a fuel injected engine. Is there a way to adjust the tension? Thanks in advance, Elmo. PS It is an awsome bike !!!

You likely have the older design throttle cables. Upgrade them to the newer ones and you will have a NEW BIKE! Not cheap, but WELL WORTH IT!

The old ones would stiffen up and make your right arm a lot bigger than the left.

Test: Open the throttle all the way, release it, and if it does not snap back quickly and solidly, get the new cables.

I second David's recommendation. My '02 was a bear to ride with the old cables then I changed them to the '05 throttle parts and cables. What a difference! You'll not be disappointed. Click here for a link to the part numbers and description of the parts. I did the job myself for about $120 in parts that included a new cruise control cable. Instead of replacing the under-cover on the right handlebar I drilled and filed a new cable access hole.

When did the new cables first become available? There was a service bulletin on the throttle cables some time ago and I got mine replaced under that (I have an '02). To be honest, neither I nor the service technician thought there was much of a change. I have felt LT throttle's that were easier than mine as well as other's that were stiffer.

I am wondering whether there is yet another set of throttle cables that I might explore, the ones for the '05. Anyone?

There was an improved set available when the service bulletin was out, but that SB ended Dec. of '03. I put these on my '01, and there was a HUGE difference, the ones I had were REALLY tight.

There was another improvement that has been posted about for a few months now, And I believe that is the '05 itteration (?), which is not just different cables, but a different cable mount/routing structure at the throttle grip area.

Yep. The link given in Ernie's post above shows the latest throttle cables.

The original set that came on the '99 LTs tended to stiffen up, sometimes so bad that the throttle would hold open by itself. BMW came out with a new set in '02, and many were changed under warranty, though that service bulletin has long since expired. The '05 cables are smoother still, due mostly to redesigned attachments at the grip.

I've installed a couple of sets of the '05 cables at various service parties, and they are worth the upgrade if your throttle is at all stiff. My bike was upgraded to the '02 cables under warranty, and they still work fine 2 years and 60K miles later, so I'm leaving them alone for now.

If BMW follows their previous pattern we should have new throttle cables in '08, probably attached to an all-new LT.

Some people see the gas tank as half empty. Some see it as half full. All I care is that I know where the next tankful is coming from...

I don't

think it is just the cables. It is also the little things you do along the way. When you go to take apart the throttle grip, pull the grip out some and wipe away the old lube if there is some. I noticed a lot of wear on the bar at the point where the cables attach, small grooves actually. Sanded it down some with medium then with extra fine, wipe away, lube with dry TPFE based spray.
The other clean and lube place is the return springs, three of them on the throttle bodies. Carb cleaner followed by air drying with compressed air then the DRY Telfon based spray. Makes a world of difference.
Could be they just need cleaned and lubed not replaced.
Do NOt lube the cables themselves though.
