Adding Horse Power to an EVO
« on: January 04, 2009, 03:13:31 PM »

What are the different ways any of you here have added horsepower to a stock EVO? With out a rebuild. Just add ons. New Carbs, pipes...etc. Just curious. I have an 87 and am currently working on a few things...new carb (S&S) New ignition (MSD). I know there has to be tons of ways to squeeze a bit more out of these motors.

it depends on how far you want to go. You can just add cams. You can do headwork too. You can change pistons and raise compression. You can tear the bottom apart and put a bigger leg in it! Depends on what you're trying to achieve! ;)

Taking a Evo to Stage 1 is completely bolt-on:

Beyond that, read the further stages on nightrider's website.  A lot of good info there.

Thanks a bunch! Perfect info. I have the SS carb and a Kuryakn hypercharger being tweaked at the Rosholt bike shop right now and am interested to see how it will perform.

Hey MrFeexit...So how is your 87 EVO doing? Just a bit curious or is it done yet?  :2vrolijk_21:

Hell no! I'm a cabinet builder/carpenter and I am in the process of moving my shop. My current shop is and has been for 11 years my garage. We actually moved most of the big tools to the new place yesterday...in 0 degree weather thank you very much, and we are doing some wiring, lighting and shelf building today. Once we have that done, one side of my garage will be dedicated to "the build". I do have my springer forks, my carb and hypercharger...they look really sweet. The guy from Rosholt Cycle is going to a builders convention and is getting my forward controls figured out. Probably JayBrake J series. We may actually do a belt drive with the brake rotor on the same side to show the new spoked wheels better. Time wise I'm not too worried...winter stays a long time in central WI.

Will Do! Thanks for asking about it. Trust me I will take a lot of pics, before during and after. The HyperCharger to the S&S carb was a tricky match up. The Hypercharger is made for a twin cam... but it's all figured out now.

Rock solid, tried and true build on those is an EV-27 or Wood 6.
Minor head work, either a CV, Mik, or S&S E, something as simple as slip-on mufflers, and a tune.
This will easily roll out 75-80 hp and 85-90 ft/lbs.
Must have done over 75-100 of these over the years.
