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? Fred

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. Z

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

Dude, Google "prevailing torque". Lotsa different types of PT nuts. http://www.boltscience.com/pages/glossary.htm http://www.katonet.com/Techinfo/Newsletter/1999/jan-feb-99.htm Fred

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. --- In DSN_KLR650@yahoogroups.com, "kestrelfal" wrote:

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. revmaaatin.

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.
