Changing K1100LT Final Drive to K1 (33/12) FD ~

[David Nimrod]

I seem to want less revs, up at 'cruising speed'.

Better fuel consumption/tank range would be good too!

Has anyone done this mod..? Did it work out..?

Would it affect the Speedo accuracy, and any other issues to consider..?

Thanks,  :2thumbup:

Put the year of your bike in your profile, David, so it will appear in every post. While you're waiting for an answer from somebody who has actually done this mod, have you read the information in these tables? The second one seems to indicate that some of the K1100LT came with that ratio. Have you verified the ratio on your final drive?

...have you read the information in these tables?

That's a fascinating page... will digest it tonight!

It's definitely 31/11 on there now...

Hi David,welcome.
I noticed your a Harlly rider....as well.A lugging,low reving V twin with a gray,I mean great,charm.
Of course you want to recreate a long legged 4'cylinder that is un seemingly busy at cruising speeds and final drive changing ratio is going to be the way to go.The speedo won't be adjusted because it just counts the rate the rear wheel rotates.
 I understand the origins for the will to do this,but I haven't done it on mine because we have twice as many corners to every straight bit of road where I've been riding and being only a 740 is down on grunt.The brick motor is happy to rev as part of the design philosophy.
  When I get back on my Guzz,I have to remember it only has two cylinders and also a funny lurch to the right when ever I blip the throttle to change gear.At least you wouldn't have to contend with that laugh.When I get back on my tripples I have to iron out the twitch on the stearing I am left with as that is redundant on a counter rotating flywheel and crank.It is also very very smooth so I'm always making sure to check I'm in top gear.
All the best and Vivre la difference?

Wise words... let me think on it :2thumbup:

My recent bikes have been a Guzzi Spada NT (1985), and a heavy flywheel R100RT (1979).

I guess I'm adjusting to a 'busy' sounding motor; I will have to get my head around the K..!

I would love a 6th gear.

I spotted a K1100LT for sale on eBay, with a tell tale yellow FD...

So, curious, I messaged the vendor, had a chat, and his conclusions:

1). It's an easy swop. once you have the FD.

2). You do get better fuel range...

3). The revs don't drop that much, about 500rpm at 100mph.

4). There are no down sides!
