I have an 883 with a 1250 kit, Andrews N cams and a S&S super E, and it rips compared to stock. I was never able to get the wheel off the ground no matter how hard I tried, and now it's hard to keep it down.

I did all the work myself and bought the cylinders used, I've only got $500 in the whole setup, minus the carb. I've been thinking of putting some worked over Buell heads on it.

 

I've stated it before, my girl has a 1200. I have an 883. Her bike is WAY powerful than my 883, but is a joke next to my vrod.

 

Hey ryanek9freak, what jets did you use on the S&S carb? I am doing the conversion and I am not sure what jets to use.

 

Probably a lot leaner than you would need, I'm at 6500 feet.

 

S&S carbs are pretty broad when it comes to jetting...just give him ballpark numbers to begin with.

 

madnss - very good point, most people miss the fine details.

The part of the NRHS/Hammer website I was reading did not have the fine print. I was stating that fact that one company (Hammer) was stating that there will only be a 10-12 hp gain, if that is the expected increase why bother ripping your engine apart and spending $800 - $1000. The other company (NRHS) was stating 20+ gain with the same kit for the same price. As stated Hammer was doing the head work for NRHS until recently and the dyno sheets from the dyno forum are showing hp gains consistent with 20+ with just the increase in cylinder size regardless of kit used HD, Hammer, NRHS, so cams, head work, etc. are going to add additional hp with proper tuning

 

The other cool thing about Hammer...is Aaron actually races. They don't just build "kits", everything is actually track tested and tweaked.

and yes...a 1250 kit, with 1200 head swap + 560 Cams makes it EXTREMELY hard to keep the front wheel planted on a hard take off. (hell, even a rolling take off)..takes some mental adjustments on clutch release.

 

I had a 883 and it was a good bike for what I bought it for then when I wanted to step up I sold it and bought a FXR 1340 the conversion wasn't even a thought thou I knew it could be done, then after 10 years I decided to by another bike and ended up with a sporty 1200 overall it is the best bike I've owned and in hindsight should have bought the 1200 from the start it would have saved me a small fortune.

 

I love my 1200 conversion and the difference in power is 100% noticeable. add pipes and a good air cleaner and you'll see even more peppy power.

 

Yeah the Hammer guys were the brains and know-how behind NRHS and they were doing all there heads for years. About a year ago they got pissed at NRHS and cut them off and ever since NRHS has been doing porting themselves. All there dynos on there site are still from Hammer's head work so dont be fooled. Says a lot about NRHS that they advertise with dynos from Hammers head work IMO.
