You gotta wait for the admins to 'approve' your registration- Can take a day or two. Dragos does some nice stuff from what I've read on it.

 

Sorry, I had forgotten about that. You'll like the site. Information overload. But hd forums is alot more fun and friendly. Here is the chart. 121 ci,640 blower cams,10-11 pounds on the procharger. We all need this setup

 

That's a lot of bike. I don't know that I want that much. But it would be fun to ride.

 

that is an impressive dyno sheet- it shows that the builder and tuner know what they are doing. Not something I'd do with my Breakout though- I already have one fussy performance monster and I don't want another. You can get more than enough reliable ponies with a normally aspirated build and it does not need to be big inches or cost crazy thousands of dollars.

Engine changes aside, don't forget about the gearing. You guys may not believe me oir put much merit in it, but these newer HD bikes come with too tall of gearing. it kills everything. Change your final drive pulleys to 30T/68T, use same belt, and then freak out with how much faster your bike is with no other changes. 3.06 overall final drive ratio- it's the same as adding more CI to the motor at much less cost. there is zero downside even for freeway guys (most all of the bagger guys do this upgrade, and those bikes already come with a larger 68T rear from HD). I'll be putting on the 30T front in the next few weeks so I speak of what I also do.

Not to mention, when you do things like cams and larger inches, SC etc, your power band moves up, and the tall stock gearing kills it even worse. you can't have an optimal engine upgrade without the right gearing to go with it.

 

Pb i didnt think you are looking for that build, but i thought it was cool to see. Hey Dog i know you have done the rear pulley. I like how easy and relatively cheap it was too. So what is entailed in the front pully change. Who makes the pulley and is there any other obstacles to doing this. By the way i do agree the bikes are geared to tall.. I cruised at around 90 all the way home today for about 20 miles and at 90 it would pull rather happily on up. With the chp and my class a license not a very good practice.

 

here's the part- it is a pulley from a 2011 tri-glide. this fits any 2007+ dyna, softail etc with the 6 speed trans. i just bought it here for $63, free ship with orders over $99. I also bought the SE 4.9 gm/sec larger injectors.

you can also try surdyke or newcastle harley davidson. i always rotate between those tree sites for parts. most of the time it comes down to who has the best shipping rate or free shipping deal.

labor is the only bitch with the front pulley. you have to pull the outer and inner primary. which is normally easy, but you need two special sockets - one for the compensator motor sprocket and one for the actual drive pulley on the trans.

a new inner primary seal, outer primary gasket, and new inner primary sealing washers. typically you will have the shop supply the gaskets and labor. you're looking at about 2 hours of labor cost (it's not hard with the right tools). so i guess this would be a $300-$400 upgrade "all in" parts and labor for the front pulley. But still not bad for what it gives you- hell you could spend more on a freaking air cleaner.. hah so buy the pulley then shop around for best labor rate.

Note! if you do the 68T rear pulley then you can use the SAME stock belt. if you leave the 66T stock pulley on the rear, you must go to a 131 or 132 shorter belt. I don't recommend that. the sportster 68T is cheap and a total DIY.

 

thanks brother. what is your calculation in rpm change at cruise speed /mph. That is a cheap mod for the gain. Hard to beat really.

 

indeed. the RPM's with a 30T front and 68T rear in 6th are as follows:

60mph 2420
65mph 2621
70mph 2823
75mph 3025
80mph 3226
85mph 3428
90mph 3630

not bad at all. 6th is a 1-1 gear though and not an overdrive. you'll get the biggest acceleration difference in 1-5 gears.

 

awesome , thanks again.

 

you'll also need about $100 in gaskets for the inner and outer primary. It would be cheaper to order them online vs buy from dealer or indy.

Inner primary kit # 25700337 (for black inner primary) or # 25700226 for chrome inner primary - the difference between these two is the outside exposed edge of the inner gasket that sits between engine case and inner primary being black or silver.
Kit is about $60.
[EDIT] you can find this kit as low as $30-$40. the Breakout comes with the silver inner gasket and the 2570026 kit is cheaper anyway. use a sharpie to black the gasket edge if you prefer.

outer primary kit, contains gaskets, seals, orings, etc: #047445 OEM #: 60547-06-KF - about $60
[EDIT] - you can find this kit for about $45-$50. JAMES GASKETS, INC. JGI-60547-06-KF GASKET KIT PRIMARY COVER

All these parts are same for 07-up softail / dyna. I see these kits cheaper on ebay a lot too.

[EDIt] - Just called around for labor on the pulley swap, Barger HD in Canoga Park quoted me $135 assuming I have the pulley and gasket kits. that's not bad at all.
