EVO upgrade

So this is what I'm doing to my bike this winter. It's mostly stock now with a thunder slide kit and drag pipes. Here goes: screaminingeagle muffler kit, se performance ignition module, se performance ignition coil, Crane fireball 310 cam and torrington b-138 cam bearing, se adjustable pushrod kit, new lifters, se 1340 evo heads. Of course I'm getting the cylinders honed, new rings and gaskets. Also thinking about taking out that plastic breather gear and adding new s&s steel breather gear. So what do you think? Am I missing anything?

I'd skip the SE coil/Ignition and go with Dyna ignition and single fire, over your double fire ignition.

The Crane fireball cam is only a .490 lift cam. I'd prefer the EV46, over that.

Jetting will need to be changed, obviously.

Here's a list of the cams you can chose for your bike. It can get overwealming at times....

Thanks for the advice. That link you posted is the same site that I got all ideas from. I'm doing stage I,II, and III. I'll check on the Dyna ignition. Is the EV46 cam considered bolt in?

Yes. Most cams for the Evo under .510 lift or so, are considered bolt-in.

I have the EV27 cam in mine. It's a good low end cam. Comparable to the old "L"-grind cams, last seen in 1991. Nice idle, good fuel mileage but a seat in the pants difference over the crappy "N"-grind POS that came out of there....

I found OEM lifters work great, and they're quiet. You get what you pay for, and watch using tapered pushrods, as they can contact the pushrod tubes and make noise.

I also set my pushrods at .0140-.0150 deep, rather then the .0100 the factory sets them at. I'm using the SE adjustables as well. ($89 set)

Look at James Gaskets pushrod tube "X-seals" for your pushrods too. I'm using those and the tubes are leak free.

Outside of that, it's set-up and tuning.

a nice mild build for VERY good low end is a S&S .520 cam,heads milled .050,SE p/rods and a dyna S dual fire ign (single fire is gimmicky,wont make any differerence for the extra $$)your better off getting your heads done over SE heads too

So what would be the major difference between your EV27 and an Ev46? also did you replace that plastic breather gear with a better one?

When the powerband comes in and lasts to. I reused the plastic breather gear.

i would replace the plastic gear too,for one,they dont stay round,and more importantly,the nylon material is actully harder than the alluminum and will score the breather hole.we have to go +.030 on most late shovel & evo rebuilds for this reason
