Oh here we go.. 10.25:1 Ross pistons installed fly cut to clear cams up to .630 lift. Pistons and jugs installed. Head porting is next.

While he was working on it, he found my rear exhaust pipe cracked all the way through. Hmm I was wondering why it was backfiring on start up recently!

That kind of looks familiar.....happened to me on way home from ES 2 yrs ago. Build sounds like its going good. What cam did you decide on?

When I left we were talking about the 255's as he had them in stock. But with the adjustable pushrods and the valve reliefs on the pistons being so big, I'll have the ability to swap them out and play around with different grinds...if I want.

my vacation is at an end. As I drive back closer to home I'm getting reports of where my bike is at in the transformation.

The latest is that the heads are decked and ported, new guides installed, larger intake valves, intake and injector body are ported, just waiting on the new valve springs to show up and the heads should be done. Meanwhile they're getting flowed so he can match some cams up to them.

This is a great time to ditch the true duals for a Fat cat. You will gain about 10- 20 tq at 2200 rpm with the fat cat. Get the wrapped performance baffle.

Dang! That's a lot to go from a TD to a Fat cat!

It made a BIG difference in the performance of my bike. It was worth the money spent for me.

I know from experience that a 10.5-1, 98 cubes and a bit more money than I spent was only 1.3-1.4 seconds faster in the quarter mile.

As someone else asked, "only?" With the proper work and tune, you will find increased power throughout the RPM range - the pipeyness will be over, it will be more forgiving, you won't have to downshift to pass or instead of 2 gears, it will only take 1.

The cam makes a huge difference. The one I used needs more compression, even if I am at the bottom of the recommended comp. My cam pulls throughout the rpm range, it may have a little less total hp, but the power throughout makes up for it. It definately is not a high mileage cam, but I did not buy a Harley for it's mileage.

Cams are in, SE pressure plate is in. All that's left is the breather box back gasket, then the rest can go together. I asked what cams he used and he said based upon the head work he went with SE253's.
