Been looking at the Jims big bore kits and it seems that only the 100ci can be used on the TC88B, all the rest are for the TC88A only..
Is the SE 103ci big bore kit the biggest option for the TC88B?
I am not looking at doing a big bore kit on my bike just yet but was interested to see that the Softail engine is not that well supported in the after market big bore kits..
As the saying goes "Ain't no replacement for displacement!!" so I figure thats where to start to get a good base of power instead of pushing my 88ci to the limit and having an unreliable engine..
Any mod that works on the 88 works on the 88B. If you go over 107" you have to bore the cases. I'm running the SE 103" that's built by Jims on my Night Train

The jims site says specifically for the TC88A thats why I asked the question..
There are a bunch of bore and stroke combos that will go into the B motor. You can go as high as 4 5/8 stroke and 4 1/8 bore to get to 124". Lots of other designs from S&S, Jims, Zippers, and others that can get you to 103, 106, 107, 110, 113, 116, 117, and 120 along with 124. The only recommendation for the B motor is to keep max revs in a reasonable range.

Keep looking. 2 years ago I built a 116" TC88B for a customer. As Csoday said, it makes no difference. The reason you see things about the so called "B" motor is that when Harely introduced the motor, the sprocket on the crank slipped when High performanced was added to the engine. In fact only a few did this, they did it on stock engines too. But most of those engines were the first ones and were sent to the east cost. Since then the interference fit on the sprockets has been adjusted. Now you can still spin a sprocket, however most people don't have that much power. Bottom line is that there are more options for you.

Thanks for explaining that Jeff S..
So how much power does it take to "spin the sprocket"?
I often read of guys with 100+hp and tq so I am guessing that it takes quite a lot more than that..
