Idle rpm

Just seeing whats the normal idle rpm on the k1300r?
I have a rexxer map installed in my bike and believe it's idling a bit high but can quit remember what it was with the standard mapping.

Re: Idle rpm

Mine ticks over at about 1150 when it's up to temp.

Re: Idle rpm

Mine now seems to be idling too high. It happily moves along in any gear without any throttle and I've lost most of the engine braking.

Easy fix or something complicated?

I like to ride but am not a mechanic.

Re: Idle rpm

Most basic check would be the throttle cable adjustment. TB may not be closing. The throttle on these seem a bit sloppy to me and some others. Some have attempted to adjust the slack out.

Did you do the rexxer map because there is a power commander type thing or different exhaust? This "high revs" is after the bike is completely warmed up yeah?

Re: Idle rpm

It will drop about 100rpm with its warmed up. I did the rexxer map as I found the bike had a very snatchy throttle response and the engine braking was pretty harsh. The map has improved, made the power delivery linear and its much nice to ride but I was out with another k1300r rider and noticed the idle differences

But there has been a distinct change in the way it reacts when I close the throttle.

It happened 2 weeks ago. One day it was fine and the next day, I rolled off the throttle behind a slowing car and had to grab the brake because it didn't slow as I expected/as usual. Played around a bit and realized it was not only not engine braking as usual but also smoothly moving along in any gear without throttle.

Re: Idle rpm

As an update to my last post above this - I took the bike to a dealer for a service and had them look at the lack of engine braking. They say it's all fine. But it's not, there is almost no engine braking now.

The gauge shows about 1100 RPM and idle.

It's difficult to describe exactly whats happening but it's something like this - If I shift down, it starts slowing down, but then there's a point at which the resistance goes away and the bike rolls on without any engine braking.

I'll make note of the speeds/gears next week and post.

I also can't make the exhaust pop anymore. Could do that without fail when downshifting.

Finally, I can make the bike go along, without throttle, in 1st or 2nd with no hesitation.

Re: Idle rpm

Not to be insulting, but I might as well bring up the obvious. Throttle cable adjustment, binding in the cables, and a throttle reset by disconnecting the battery then rolling the throttle. Might locate someone with a GS911 and check the cycle. Idle control sometimes called an idle air step motor might be wacky. Good luck

Don't think it's insulting at all.

Just the sort of help I'm looking for. Much appreciated.

I'll try the reset first.

If that doesn't work, I'll take it to an independant shop and have them take a look and point out what you've said.

Can you swap the stock map back in and see what happens? Also, try this. Disconnect the battery and turn the key on. Then wait a minute. Turn the key off and reconnect the battery. Turn the key on and do the TPS recalibration. Turn the throttle to full open, count to 10 and close. Repeat 2 more times. Turn off the bike. Wait 30 seconds. Then turn it on and start it. If that fixes it, it was the TPS either not being calibrated or drifting out of calibration due to wear. You have to recalibrate it every time the battery is disconnected.

Re: Idle rpm

I ended up removing the the rexxer map, re installing the factor map and re connecting the lambda sensor (that I was advised to disconnect) as it was running a bit rich. Now have installed a Booster Plug, as recommended by a BMW mechanic and bike is running better now.
