Hi All

I guess this question came up before, but I am new to Valks, so I don't know.

With a "normal" V-twin bike, it is easy to know when the carb or one if the two carbs is not working, but how would you know if one of six is not working. Will you even pick up if the bike is running on 5 cylinders rather than six? (I do not have any perceived problems with my bike, just wondering about this)

Let me know, thanks!!

You will know when it drops a cylinder just like ya would with your car, or your "V" twin.

When in doubt, feel for a COLD header pipe.  dead hole = cold exhaust pipe.

When you drop a cylinder you can feel it. Just shut off the fuel while riding and test it. You will feel one drop, then two, three, four, then it starts feeling like a Harley.

as stated...you want to experience the bike running out of gas...next time out...just reach down and turn off the petcock.  You will feel the bike start to shudder a little as the first carb drops out...and the shudder gets worse as more drop off.  There is also a noticeable difference in the sound.

pull a spark plug wire.  You will notice the difference.  That is a good troubleshooting method if you think you have a bad plug or carb problem.  If it changes the sound, it is working.  If it does not, you have found your cylinder with problems.

Hi, no, I do not think I have a problem, it is just with so many pistons doing the work, you might not notice a lazy one.

I am not sure how much oemf the bike should have, since I have never had one before, but it feels pretty damn good - let me assure you about that! It is just that I do not have anything to compare it with.

If you are used to a "normal"  Grin Grin {what ever that is} feel of a V-twin powered bike you will notice the Valk is a different animal. Big V-twins have a lot of instant low end grunt right off idle. The Valk {or any other flat 6 powered bike} has a smoother power delivery that is more like a sport bike. The Valk will putt around real docile like at lower RPM but....... twist the throttle & get her up on the tach a bit and you will feel the difference!
Six cylinders with six carbs means six sets of ports to get the fuel/air mixture in & out veryfast. Complicates things a bit but it sure is worth it to me!! cooldude

To me when one drops on the road, the bike slows a little and requires more throttle to maintain set speed.  When the second one drops, same symptom, with less throttle response. When the third one drops all doubt is gone, you know it needs attention.
