Idle lowered on its own..

[SDB]

Have had many Yamaha's and for the 1st time the idle seemed to lower by itself over time. I set I set it to 1100 RPM with a tach when I 1st got the bike now after 2000 miles it's dropped to 900 and even stalled at a light. Bumped it backup to 1100 seems fine. Anyone else have the experience for their bike losing idle over time?

Make sure it's the actual idle thumb screw is moving. Maybe a dab of finger nail polish. Idle can change based carb sync, throttle cables and will lower some with a dirty air filter.

When i got bike...all fluids and filters changed new ngk plugs gapped correctly set warm idle to 1100...synced carbs....rechecked idle....no intake leaks etc. Bike was flawless until just last ride and idle was low. Thumbscrew not easy to turn (not loose). No biggie just wondering if any others experienced this with their gen 1.

I've never re-adjusted my idle speed.
