help - a14 not shifting when warm

[Mike Huber]

The same thing happened to me recently too...Walmart was out of Rotella T6 synthetic so I figured the Walmart brand synth would be OK...Wrong !!!! Shifting became a PITA....O'Reillys had T6 in stock and I got a 20 mile oilchange and learned something in the process....Now I got my "buttah" shifter back and all is well...

I notice on my bike that when my oil is older, neutral is harder to find and shifting is a bit "clunkier". When the engine is cold it's not a problem, but after it heats up it becomes more apparent. I did an oil change on the road and could not obtain my regular oil one time and the "problem" was worse... to the point that in order to actually get into neutral I had to kill the engine and then find neutral. And once again, this was only when it was hot. A fresh oil change and it was back to feeling like "buttah" again. This was observed at around 20,000 miles in a KLR that has been strictly maintained with only full synth every 3,000 miles its entire life, so I don't think the probability of wear being the problem was very high. -Jeff Khoury From: "argonaut10" To: "DSN KLR650" DSN_KLR650@yahoogroups.com> Sent: Thursday, June 16, 2011 7:07:47 AM Subject: [DSN_KLR650] HELP - A14 Not Shifting When Warm I'm still stumped as to this problem. My KLR650 A14 dual-sport recently had a harder time finding N when warmed (this occurred over many months this Spring). After coming off the highway a few weeks ago, downshifting to 1st, I was unable to move out of first gear to proceed through the light. Once cooled I was able to shift gears. What is the issue with my transmission/clutch and why does it only occur when warm?
