counter shaft / front sprocket change

I removed the stock 15 tooth sprocket and replaced it with a 16
tooth. There are significant differences between the two sprockets.
Most notable is the lack of the heavy rubber bushings that sandwich
the stock gear. If anyone has any experiences especially a bad one
to share regarding the doe's and dont's of sprocket changing please
respond.
I test drove the KLR and it will now run 70 Mph. at around 4 K on the
tach. I like that part.

I put the 16t on last weekend and took a 20 mile test drive: very
pleased. The 16t makes 3rd and 4th usable around town and makes
highway cruising a lot more relaxed. I haven't completed a tank yet to
see what it does for mileage: I'd expect it to help by 5-10% or 2-5 mpg.
While the manual recommends removing the chain from the rear sprocket,
I found letting the wheel go all the way forward gave enough slack to
change it. Did have to adjust chain tension with the new sprocket.
As an aside, I don't know how anyone does any serious off-road [not
dirt road] riding with the 15t.

I tried the 16t a few years ago. it did nothing for my fuel consumption, and sapped the
already anemic top-gear roll-on. These effects were overshadowed, however, by the
doggy performance around town. Almost lost amid all the excitement was a slight
relaxation of the engine at highway speeds.
The 15t is fine on the highway and for most all-around use. If I can anticipate steep or
slow going, Jake's prevailing torque locknut makes it possible to swap to a 14t In about 10
minutes.

Wouldn't you use the same torque with the PTN?

The massive flywheel, e-start and powerband of the KLR make it easier to
ride offroad than 2-strokes in many cases. Many years ago, Devon and I
did a match race in the pouring rain, the trail was pretty much mud or
slick, wet rock. We passed many riders simply because we didn't stall
out in the mud, and the torque of the KLR comes on so slowly that it
basically acted as traction control. The 2 strokes would peak and simply
spin their wheels in the wet conditions.
If you want to really offroad, 13T is where it's at.

Can someone tell me what the term "prevailing torque" means?

Dude, Google "prevailing torque".
Lotsa different types of PT nuts.

And to think, for 50 years we been calling them things Lock Nuts in
the mechanic industry. Guess we were not politically correct huh? Ha
ha ha ha ha. Prevailing Torque huh? Amazing.

Hi Zac,
I am sure you mean 13/43 when you say 13T is where it is at. Y or N?
I am going to go to a 16/46 (the Saline solution) with my next
change, allowing for a 14/46 off road (again, the Saline solution)
with a 13T held in reserve for an experiment.... 14/46 is a near
exact equivalent for 15/43, and dropping the CS to 14 makes first
gear usable (at our experience level) without slipping the clutch a
lot.
The 46T was available through a connection in AU, and is not
available in the states. For most of us, the 45T would be a good
substitute (IMO) for the 46 without all the hassle of importing from
AU.

Sorry,
I said, "14/46 is a near exact equivalent for 15/43"
that should read: the 16/46 is a near exact duplicate for a 15/43,
ratio wise. revmaaatin.
