I hope this is not a stupid question but I'm new to Harley's, I bought my first HD10 months ago a
05 FXDCI.I have a question about the TC88 engine. What is the difference in the TC88A & the TC88B engines. I have noticed this while reading these forums. Please enlighten me.

 

I believe the TC88B includes a balancer shaft to reduce vibration and was introduced on the softail and is solid mounted, the standard 88 is rubber mounted to reduce the vibes.

 

Mal... is that an enfield single on your sig?

 

Hi Joe, an Enfield single in my sig? I actually did have a Enfield 500 Bullet single till a few weeks back, I had to trade her in on my Dyna, also traded a sportster 1200S as well I wished I could have afforded to keep the Enfield but money was tight and the FXDX is mega, do you have an Enfield?

 

The B in 88b stands for balanced. The motor has a counter balancer in it to keep the engine smooth.

 

I do believe malcs avatar is a two stroke motor, notice the fuel flowing thru the reed block and the firing on every revolution of the crankshaft.
