I'm thinking about sending my heads to Hammer and getting some head work done and putting in some 560 cams and taking it up to 90 horse power this winter. I'm still riding the bike so don't want to tear it down yet but when it gets cold I will do it. Probably should have done it when I went to 1250. I've found out I'm not too old for a good project.

 

I was looking at their website and the price for porting seems very reasonable. My 883 was the recipient of a 1250 kit and cams from the previous owner and I'm thinking about the Impact level port job this winter as well.

 

90 HP and that bike will fly.

 

Yeah it will. lol

 

It's fun. I need to get mine on the dyno and dial it in. Cheapo no tach. dyno said 86hp. I'll be triple digits on accident passing someone 2up...oops!

You might hit some hangups getting to 90hp with the reverse dome pistons, but headwork will help either way as the 883 heads choke before redline as is.

 

I'm going with 30 degree reverse dome 10.5/1 pistons. Hammer says it should be no problem with the head work and porting. I will be using 560 cams.

 

Good choice. That's what I have in mine. Excellent combo.

 

Thanks, glad to hear that. Have a good one.

 

So that means new pistons then? Agree, would've been better do do this
from the start so you wouldn't have to pay for pistons twice....
I went the expensive route & bought new XL1200 heads, then had Hammer do their Crush CNC port job on them (big valves, beehive
springs, Ti retains) also with the 30 degree pistons. For my application,
I chose the Jackhammer 570 cam (like the torque down lower)

The whole shebang (big box) showed up yesterday, but I've got quite
a bit of 'life events' happening at the moment with my mother-in-law
so it may take me some time to get it all installed.

Let us know how it all works out.

Yeah should have done it at the start but retired and got the money. Can't take it with me. No biggie.
