I'm hoping to rebuild a 1275 this winter for our BE and would appreciate thoughts regards a proper dampner (dampener; damper). We just pulled its 948 and it has just a steel pulley on the front; I believe that the 1275 can benefit/requires a proper dampner, but there appear to be a few available with a great variety of prices and would appreciate some guidance. Thanks, Doug
 
This is a totally uneducated guess, (worth 2 cents). Since balancers are individually balanced any one would have no effect on the overall engine balance. However, if you chose a "high performance" cam you MIGHT benefit from a bigger balancer to counter the inherent roughness of the hot cam. On the other hand if using a stock cam I would go for the smallest. lightest balanced available to possibly aid in acceleration.
 
You need a dampner on the crank pulley for a 1275. They did not come or are then needed on the 948s or 1098s. I'm not sure where to get one other than the usual suspects. Used ones are generally worn out.
 
We put a new dampner on our BJ7 a few years ago, but lucked out in that BPNW had a sale on. Doug
PS: yeah, and the old stock one was definitely junk, due to time.
 
Damper or dampener, not dampner! Try spell-check.

The long stroke of the 1275 coupled with the relatively heavy piston causes vibration that should be damped.
 
Hmm: Bill Gates has learned to spell! I just tried out tyre, damper, dampner, dampener, neighbour and favourite in Word, and Bill was happy with all the spellings. However, Google appears to still be challenged regards 'proper' spelling of the Queen's English... Doug
 
The 1098 is actually a longer stroke engine than the 1275, probably partly why the 1275s love to rev so much.

Mini Mania has the best selection of upgraded parts for A series engines, including dampeners.
