I have Baisley Heads (1.94 intake, 1.63 exhaust) on my 103" FXST. Cast HD Flat Top Pistons, Roller Rockers, Fat Cat, Wood TW6G-7 cams...makes 100/110. My clutch was already somewhat damaged from slippage with the SE spring, but with this set up, it got smoked. Had to replace it with the SE Race Clutch.

 

you can eleife cut the pistons no problems its done all the time on the new htt site some one had step by step instructions or you could just call Scott at hillside he can tell you how much.

I asked the local professional about the cast pistons today with my build and he said don't waste my money on forged pistons. He's doing the heads incl. Ferrea F0046 1.9 intake valves and Ferrea f0045 1.625 exhaust with .050" decked and said there will be no issue with valve relief in the cast units.

I'm still searching cam selection since I can't get the .530 lift I'm looking for.

 

cant say fu.kup here.

 

what about a 37g or tw6 ???????

 

Thanks all for input. Thanks for the clutch tip too.
I doubt that I will be hitting the 6200 rpm that often, just want a little more power for passing the 18 wheel guys and staying ahead of the cagers on the freeway.

Sent my seats out to get gel inserts in them, so the comfort level should be better for those 200 mile rides. :-)


Also, feel free to add personal reports, impressions of after the 103 build for your ride, and smile per mile factor.

 

How about the woods 44 mag cams? I used them in my 107 build

Is yours the one with the video posted earlier? It would have been so much better without the wind noise in it but it was great to hear it. One thing I like about the lower lift cams is how they don't let eveyone know you're running a hot rod until it's too late, lol.

That 44 mag cam has some good #s, I was comparing the cams on the Woods website and like that one a lot. What holds me back on it is the timing. What I've been looking for has a shorter duration and timing is 8 degrees faster.

Here's what I want: 16/44 - 44/16 240/240 .530/.530 104/104

It's an old evo grind that was made by the company that currently makes the Screaming Eagle cams for Harley. That cam was THE cam and it seems nothing is coming close. Even the Screaming Eagle cams jump all around those #s without matching up.

 

Anyone want to chime in as to their " after" build experiences - that their bike runs better in such and such a way, better this or that etc.

Also, will the stock MoCo throttle body work that well, going to a 103 build ( gotta check Zippers Performance to see specs on 575 cams- I have and will use for the 103 build, and or do others change up to a bigger t-body; my compression will be 10:1.

Thanks again all. Mark

 

Hi
Yeah, I checked out the AIM clutch set up. I e-mailed my Indy and he was checking it out too. Think that's going to be the plan. Will be nice to save my arm and not slip or fry my clutch out.
