Vulcan Voyager rpm

[K-Voyager]

Hello Folks,

Could you guys please tell me the behavior of your Vulcan 1700 for these three scenarios?

This is for my Vulcan Voyager 2022 (stock).


1. Idle rpm:
- Once the engine is fully warmed up, the rpm will stay stable and drop down 50 rpm every 10-15 seconds, regardless of the idle settings.

2. Holding the clutch at high rpm:
- If I accelerate the bike to higher rpm (like 2000 rpm or above ) and then hold down the clutch, the rpm will drop below idle and then bounce back up.

3. Hot start rpm:
- When restarting with a hot engine, the bike will fire right up, then drop the rpm below idle for a second and then maintain idle usually.


Thank you so much for your guidance. This is my first V-Twin, and I am unfamiliar with its behavior (I only have experience in inline-four engines).

Best regards,
K

In addition to the above post:

- My bike never stalls in any of these scenarios.
- For the idle rpm, there is not that much swing, but I could hear the engine rpm difference (just slight rpm needle fluctuates).

Thank you again for sharing and helping.

Try cleaning the butterflies, located behind the right side engine air intake cover. Use a toothbrush and Seafoam spray. Also a lint free rug works. Spray the butterflies and the intake plenum, open the butterflies and go deeper, and brush or rub all surfaces until clean and then repeat once again.

Thank you, Chuck. I will find time and try that!
