3. does anyone know a reputable engine builder in GA that can do it

Thanks in advance

We have a great kit for the guys and gals with the new 07 96 cubic inch bikes.

This is CNC porting your heads.This kit with the flat top piston will yield 10.1 compression based on stock cc volume. Compression can be raised or lowered if you so desire.

Take a look at the packages offered by Head-Quarters:

http://www.head-quarters-usa.com/sporttouring06.html

The 113" kit uses the HD Bigger Bore cylinders (4.060" bore), forged pistons custom fit to the honed cylinders, pistons with rings istalled and gapped, etc.

A really good feature is that the packages come with a map (SERT or PCIII) that is very close to an optimal tune that you can load and ride the bike immediately after the build is complete.

Also, HQ is now offering an EFI Pro Tuner that uses your O2 sensors to maintain the a/f of your PCIII or SERT map.

Dalton, PhilM, and Pirateye on this Forum are doing 113" HQ builds.

Good luck.

 

Ikro- i put this build into a Dyna late last year and put the Fatcat on this. I made 121/128tq. Once i had the tune done, the bike ran beautully and was just a ton of fun to ride.

I'm now getting the 107kit with the 615/585 cam and the R&R heads setup as i have moved to an '07 SG with HP Inc 55mm T.Body and the Fatcat. I have no doubt that it will pull really well down low and continue to pull to the redline.

Parts you may want to look at would be using the SE upgraded injectors for the stock T.Body.
If you wanted to look at other kits, then the Headquaters 103 build and the 107kit from HillsideCycle.com are the go.

any of these builds will stomp on 103 kits and would be lots of fun in Baggers- i will find out very soon.

I have a GMR 107" build but opted for better heads, aftermarket cylinders, higher compression, gear drive cams, and an enlarged throttle body. Great company to deal with.

 

You'll need to upgrade your clutch. The TPP lockup is a pretty good unit. There are others that are equally compatible.

 

Thanks guys --- now I am seriously thinking 113----I know if these guys Dalton, PhilM, and Pirateye are doing it's got to be some good chit
