Is that normal ??
Hi all,
few weeks ago I replaced my 1200 sporty with a 07 Night train.
It rides fine but I feel kind of smooth vibration or buzz transfer to my legs thru the foot control beside increase in vibration in high speed (reaching 85 m/hr)
I let a buddy of mine to ride it (whose into bikes for more than 15 years), he told me not to worry as it is typical HD.
So guys what u think? any rules to differentiate between normal and abnormal vibration?
Can some body post the proper gear shifting timings? as some time i notice the whole engine starts to shake which is due bad shifting timing !!
thnx

On a stock?? 07' Train with the 6 speed and the 96" accelerating under normal riding conditions I would probably be shifting that bike into 2nd at 20, 3rd at 35-40, 4th at 45-50 and then into 5th as I hit about 55MPH using 6th as a Hwy cruising gear at 65-70 so long as the bike isnt falling on its face.
Heres a calculator to figure MPH based on RPM:http://www.nightrider.com/biketech/calc_speed_rpm.htm
Your motor if stock is quite happy shifting at 3500-4000 RPM as your TQ peaks at about 3500 your HP peaks at about 4800-5000. There is a sweet spot in there. You will feel it.
The rev limiter is pretty effective on the stockers and you would know if you were bouncing off it.
The Softies have a solid mounted motor....A motor with a 100 year old design that....Vibrates a lil' bit.

the buzz is the counter balance in the motor. try changing the oil.
I run the oil in the engine but use Bel Ray for the trans and no wine or clank and I can find neutral. I use Motor Factory® Primary Case Lube in the primary. because Amsoil has gone up so much I just switched to Mobil 1 for vtwin and it works as good. I have 36,000 miles in about 1.5 years and it runs great and no debris in the oil changes.

That kind of vibration/buzz is normal, personally I would be more concerned with what's going to pop up in front of me than a little vibration at 80+MPH.
A bike as big, long, and heavy as a Softail isn't exactly my idea of the best bike for dodging wildlife or crap on the road at high speed.
If you want to experience really bad vibrations, try getting the bike up into 6th gear. Then let it slow down to around 45 and try rolling the throttle on fast.
Believe me when I say you will not want to try it more than once because you'll think the engines trying to leap out of the frame on you. But it will show you what to avoid in the future.
In any case just like a car, when in doubt, downshift. The rev limiter should prevent you from exceeding common sense and blowing the engine at the high end. But the factory ECM program can't prevent you from lugging it to death because you were in too high a gear at too low a speed.

I have an '04 and so I have the 5 speed 88b motor. I experience an unpleasant chugging, felt vibration at 60 which dissapears at higher speeds. I know its normal but it annoys me because I like to cruise at that speed. I feel it underneath the bike and if I place my right foot onto the pipe-that's the source.
I also get some throttle hand numbness at times. Only my throttle mirror seems to vibrate. The left mirror is calm. Just quirks of a particular bike.
I miss the po-ta-to po-ta-to po-ta-to that my sportster(s) all sang. The counter-balanced engine is almost honda-like in comparison. (Forgive me for the comparison) But its almost too smooth. It offers a different, buzy vibration rather than the agricultural chug I've come to love. But I'm quite used to and love my new (used) NT.
