Hello everyone, newbie here. Bought my first Harley a year ago, a 99' Fatboy with 2in2 radius V&H, 42 Mikuni Carb and a mild Cam. Rode it to Sturgis 75 this year from CA with no problems but noticed I had to down shift for passing power. So my question is if anyone knows the ID of the cam I pulled from my bike? Pictures below. How will this compare to a Andrews EV27? Also upgrading to Thunderheader.




7-0004B M markings on it








30259 at rear lobe





98 at first lobe.

 

If wanting to put all doubt aside to establish more power with that EV-27, remove .060" from the cylinder head gasket surface, and use a .030" head gasket.
Your buds will suspect you did MUCH more, than just simple work.

Hey Scott, what will a thinner gasket accomplish?

 

Higher compression.

 

Ok, so if I will be taking off my heads to install .030!head gasket should I do anything to heads? Ive been going through forums and lots people posting best compression for EV27 is 9.5:1-9.8:1, I have stock heads in my 99 EVO Fatboy with 19535 miles on it, what can I do to achieve this? And should I do a valve job on them? Recomendations?. Oh, i got the Andrews EV27 and S&S quick Adj lifters.

 

Yes, as I mentioned, removal of .060" from the cylinder head gasket surface, and what we call our Super-Stock valve job.
You could also increase the intake size to 1.900" at the same time.
The .030" cylinder head gasket will also create a tighter squish/quench.
Must have built this, or an EV-3, or Wood 6 combination now over 100 times.
BTW, the fuel economy will go up, unless of course your right hand becomes heavier........hahaha.

Thank Scott for the info. to get an idea to what im getting into, what would be the cost to do a super stock valve job with 1.900" intake?

 

Could you phone us to discuss?
