96 inch build options

woods · #1 10-26-2009, 11:17 AM

I am looking to add some power to my semi stock engine.

I already did a stage 1 to it and am looking at my options for the next step.

Not sure if I want to go all the way to a 107 build right now or do this thing in steps.

Would a cam that is intended for a big bore build work OK with the stock pistons?

I don't want to buy a cam for this engine and need to swap it out when I go up in cubic inches.

Anyone keep the same bore and just up the compression to match the higher end cam?

What kind of power difference would I see between a high compression 96 inch and a comparable 107 inch build?

I would still do headwork with either of the builds that would have new pistons.

The primary use for this engine will be touring.

Sounds like I am rambeling

Any imput would be great.
Ken

I just stuck a SE-204 cam in my 09 FLTR. I got around 82hp and 99ft/lbs torque. Also alot of the touring crowd has been going with the SE-255 cam. If you don't ride above 4000 rpm, then you might consider that an option. There are lots of cam options available, it's just a matter of chosing the right one to suit your riding style. I've heard alot of good things about Woods, Andrews, and HQ cams also.

Call Don up at http://deweysheads.com/ He's a good dude to talk with. I'm sure he can steer you in the right direction.

For what your asking for I would use the Andrews 54 for a stroker. From 96 to 107 I would expect to see 8-9 more torque and horse.

Wood 7H with a 4* advance gear for now, and then when you pull the trigger on the 107"/heads re-worked combo, pull the advance gear, and you'll really let the badger loose then!!

Thanks for all of the info.
I will probably go with one of the above cams.
I feel better getting a few more miles out of these pistons and cylinders before I swap them out. Plus that will leave me a little money for other projects for now

I still can't decide between the 204 and 255. There are PCIII maps out there for 255s, but none for 204s that I can find. I want to run the bike for a bit before I dyno it, in case I decide to do heads as well. I've been told by reputable sources that the 255s work wonderful in a stage 1 96" motor. Personally I like the sound of the 204s better, and they seem to make about the same numbers. The trick is finding a deal on them, as Harley quoted my $300 for the 204s.

2wheel, check the for sale touring section. I saw someone had SE-204's new in box for sale.

George,
Don't forget our carbed 103" that Dave tuned, that showed almost 120/120, SAE, after 4 years of being flogged, before he tuned it.
