88a or 88b

What's the difference between the twin cam 88a and the 88b???

To B, or not B

The TC-88B motor or B-motors, are for the Softails. The motor and tranny are rigid mounted, so there is a vibration issue to deal with. So to keep the butts of all the Softailer's happy, you get the 88B.The 88B has twin counter rotating balancers to cancel primary engine vibration. The draw-back (if you concider this a draw-back) to the 88B is that it cant turn as many RPM's as the A-motor, thus, you can not make as much horsepower. (theoretically)

Torqued

Yes Sir. Torque is not a bad thing, and alot of people will go through great lengths to achieve it (torque). Harley & Torque have been mated together alot longer than Harley & Horsepower.
