Giving out static compression numbers is really kind of meaningless. What matters is the running compression of the cam and the powerband the user would like to obtain. I have built street engines with almost 12:1 static compression ratio where the ccp would be acceptable for pump gas and also have built engines with compression well under 10:1 where ccp was much higher due to the short duration low overlap cams.

So I say before giving out any recommendations, BaggerDave should tell us where he wants to powerband of his engine, and how much power he is looking for from his engine.

 

Pardon me? Sorry, didn't mean it, I swear.

 

Well, the Dealer just picked up the Bike, so I guess I'm commited now!

 

Save your money....most head work only comes into play at high RPM, which is not where most street bikes are ridden. Ya it will make some difference, but it is not worth the cost.

 

A cam change or gear ratio change would be better money spent.

PS I am going with the HD heads because I feel I will have more support/warranty coverage with the Dealer should issues arise.

 

Ok, you guys got to me!
I just called the dealer and said DON'T do the heads. Instead I am switching out my SE 203 cam for an Andrews 37G.
Now don't change my mind again! [:@]

 

Good move....just keep compression ratio under 10 to 1.
This is same cam I used and it worked great untill I raised my compression to 10 and 1/4 to 1. Then it pinged. Cam works great otherwise. In my opinion it's the best cam out there. The gear drive qets quieter after you get some miles on it. I at first didn't like it but it quieted down and now it is fine. One more suggestion if you have the money is to put in a Fueling oil pump at the same time. Additional labor is minimal being you are already in there. It will make engine live longer and makes bike run a little cooler.

Are you having the stock heads ported?

 

Not right now. Just a Cam change.
