The Twin Cam engine has a chain driven counter balancer creating less vibrations. As far as I know, the only other 45-deg. V-Twin bike to use a common crank pin is the Honda Shadow Ace American edition in an attempt to attract buyers by copying the Harley sound…and vibrations.
Why are the cylinder and crankshaft offsets the same?
In the standard engine those are at g and a respectively, diametrically opposite each other, so that the distance between them around the crankpin circle is the same in each direction and therefore the mean linear velocity of the piston is the same on upstrokes and downstrokes.

Why does a Honda engine have an offset cylinder?
Discussing the benefits, Honda says, “Another slick bit of design work further reduces engine friction: The cylinder centerline is offset from the center of the crankshaft 4mm toward the exhaust side. Doing so reduces the lateral resistance generated between the piston and the cylinder during the power stroke.
Hot-Shot Motorworks has reconditioned 1,000’s of Harley Davidson T/C cranks since it was introduced in the T/C engine in 1999. The crankshaft that is used in the XR750 is virtually the same as what is being used in today’s T/C engine other than a difference in the stroke and rod length.
How does a crankshaft balance work on a hot shot motor?
After balancing is complete, the flywheel components are pressed back together to exacting tolerances and trued to within .0005”. Then a special crank pin plug is installed in each end of the crank pin causing, extra pressure to be applied to the crank pin/flywheel half.
Are there any aftermarket crankshafts that are balanced?
Similar problems occur with aftermarket crankshafts as with the original equipment. While the aftermarket crankshafts may be balanced slightly better, they too are dynamically balanced and will eventually shift.
Can a crankshaft be turned to spin the cam shaft?
If the crankshaft is turned to put the timing mark 90* before top dead center, all 4 pistons will be half way down their bores and you can spin the camshaft with no chance of a piston/valve collision. You need a good manual.
Why do I need to change the cams on my Sportster?
The first reason is to change out the cam or cams and if that is your intention you should know that as part of that process you should cut your standard pushrods with a bolt cutter, pull them out and replace them with adjustable pushrods.
Can you rotate the cam shaft on an OHC engine?
Rotating the camshaft on an OHC engine is easy to do when your pulling the head. And even just changing the chain. If the crankshaft is turned to put the timing mark 90* before top dead center, all 4 pistons will be half way down their bores and you can spin the camshaft with no chance of a piston/valve collision.
What’s the difference between 03-present and 04-present Sportster heads?
03-present Buell heads can be considered the same generation as 04-present Sportster heads in that they use large fins and 7/16 front mount fasteners with the right front mount hole moved inboard 1/4″. The main difference is that the XB head does not provide head breather/carb mount bolt holes.
