Hi pl427
I love these bikes. Vertical twins of this era vibrate, is just how it goes. Engine design was simple back then and no counter shafts are used, so there is a degree of vibration at low revs produced by 2 big bore pistons that will make the handle bars get a real bogey on at idle.  If the carbs are out of sync,or need a tune, then you may have a lazy clyinder at idle that is producing the vibration also. Not sure if your bike has them, but some have rubber bushes that mount the handlebars. These can get sloppy with age and may need to be replaced. Another trick if the vibration is anoying you is to mix some lead shot with silicon and fill the ends of the handle bars up to "weight" them and reduce the vibration.
click here to see one walking on its center stand. Notice the way everything is vibrating on this old girl.

Excessive vibration on my Dyna


17 years is a long time for engine rubbers on a v twin. But if the vibration is only in the handlebars, you might want to fit some heavier handlebar end weights. They are there to absorb vibration(they act as dampers.) But, if the vibration is in the engine, it may be worth checking the ignition timing. On a Big V the ignition only needs to be out by a small amount to set up a noticeable vibration.

This rough idle business; With the AC on at a stop, the idle is about 600 to 700 rpm and vibrates the cabin. Can the dealer change a computer setting to correct this?


Problem on focus too . Without A/C on it idle's smooth . With A/C on the PCM - engine computer should raise the idle rpm. 850 . The only way to raise the idle would be to have PCM flashed programmed with up dated software . Adjusting the idle anyother way would cause check engine light problem , Wouldn't be able to get it to go out. Your best bet ,take it to the ford dealer and have the PCM reflashed .

I have a 71 norton commando and the kickstarter has stripped, is this going to be a ***** to fix. how involved is it going to be?


Hi, W/D here.

It doesn't look too bad. Parts were my greatest concern for you, but they abound. I did a Google search for "71 Norton Commando parts" and found many sites for parts, wiring diagrams and exploded diagrams. One site that I liked (it was a quick look-see) was genuinemotorcycleparts.com. Other sources for parts included eBay. Give the Google search a try.

Best regards, --W/D--

Plugs keep fowling up after 50 klms on a norton commando 850 any ideas


Fouled plugs are an indication of a too rich air/fuel mixture. You need either more air (clean air filter) or less gas (adjust main jet needle position lower) or (smaller jet).

Easiest way to remove the motor mount under the injector block


The best thing to do is to turn up the idle to about 850-900 rpms with vehicle in park with it in gear and ac on you need at least around 650-700 rpms or it will vibrate.

Car vibrates at idle.


you may have a pulley out of balance. ie harmonic balancer, steering pump, alternator. try increasing idle, set it at 850-900.
