Just did a 200 mile ride today. 80 mph give or take the whole way.

When my R* goes through something like that it idles way high when I stop. Anyone else experience this?

Few things come to knd when that happens.

1) throttle didnt return all the way,maybe needs clable adj ?

2) Since it's a FI motor maybe after running it hard at that speed for a while it puts it into a diff fuel curve for leaner idle mixture ot higher idle speed even though it should have no reson to do that.

3) possibly the ign timing didnt back off at lower engine speed when returing to idle after the hard run.

4) Maybe TPS is on edge of proper adj so when bike/motor/cable/throttle linkage are all heated up & the metal they are made of or are attached to has expanded a few .0001 thes making the idle higher.

If you now got your bike running much better in all other aspects/throttle positons other then a high idle post fast cruise speeds i'd leave that alone esp if it will go back to normal idle post shutting it down and refiring a little while later after it cooled down some.

BTW,my 06 silverado with carb did the same thing when i took it on my 1st trip and was cruising in the 70-75 mph range for 1.5 hrs or so (31T pulley = rpm at cruise then 32T pulley) when i stopped for a quick break where it idled considerably higher then normal (approx 1,200rpm vs 950-1k rpm)),didnt bother going after that issue becasue it wasnt a big deal and bike/motor ran fine ither then that .

Likely some fine tweaking on PMS or pilot jet/circut would cure that but since it runs so well other then that i am leaving well enough alone at this point since these stock R* carbs can be such a PIa at times to get calibrated correctly in the 1st place. It's close enough for rock & roll for me when it seems to run well at all other times.
