Default 1200C need more power.

Bike has a stage one. I find myself WOTing more than i expected i would do. I need more power.

I dont want a vrod for sure. Dont think i want a bigger bike either. I ride mostly in the city and i can run through traffic with ease.

so what are my options? Isnt it silly to bore a 1200 cc just to add 75 cc? should i do it with cams and i dont know what else?

wait till hd buy duc and get a harley xdiavel?

i have a 1275 kit with 10.5 compression as opposed to the stock 9.7.
560 cams
560 porting service

It is a rocket ship.
If you are gonna do it. You may as well do it once and do it right.

If you're just looking for better acceleration, try an 883 transmission sprocket.

Easy way, swap to 883 gearing. Highway performance will dip.

Long way. cams, heads/headwork, pistons... or twin cam

​​​​​
it does seem silly to swap for 75cc but, if that's what you are after then more displacement isn't going to hurt...Madnss wouldn't call it silly.

cost me about $1100 before eccentricities, failures, and nonessential nonsense. I did it for practice so not much care went into cam selection etc, i just followed bwana1's 98hp formula. I made a few changes but,:

I got the tuner off of ebay, three years ago $300
I got the Harley parts 15% off msrp, no tax.
Total of all parts was less than $2000 and I ebayed the heads for $350

I'm a happy camper

Call Hammer Performance and tell them what you want. They will tell you what can be done and give you a quote.

More power? You mean you're not satisfied with beating up on 883's and Honda Shadows? I'm more and more realizing that my stage 1 1200 is not a fast bike and to make it fast you have to stop bleeding your wallet dry for a few hp here and there. Either drop the few thou for a 100+ hp kit or realize you have a respectable cruiser. A gear change will give you a slight fix that'll be good for day 1. "Drop in" cams (no head work or clearancing) are cheap if you install yourself but only good for a couple/few hp. A few hp is not going to keep you off of WOT.

se-536s are "drop-in" i think 551s and 575's are too. all that power will be up top though

Not all Stage I's are the same. In fact, many folks say they can't even tell a power difference after they have done a Stage I on their bike.

DK Custom Stage I's are all about performance, and many times our Stage I bikes outperform Stage II bikes, and even stay close to some Stage IV bikes.

Here's a chart showing an almost stock 1200 compared with a DK Custom Performance Plus Stage I. 17.5% increase in Torque is something definitely felt in daily riding.

AND, if you do go with cams or a CI upgrade, you want to have great Stage I to build on top of.

I did a shaved cam cover so I popped in some N4s while cover was off. Only other mods are Bobcat exhaust, DK outlaw 425 a/c and FP3. I'm barely faster than a friends rubber mount 1200 with pc5 and 2-2 pipes. But I am at least 50lbs heavier as well.

After I did the cams I'm not sure it registered with my butt dyno. I assume I was going faster but obviously not so much to clearly notice. My sweet spot shift point seems to be 6k.

Funny thing is another friends carbed 1200 with rednecked 2 into 1 and no other mods except for proper jetting eats me up. He calls his motor the unicorn.

fwiw
