You will also need a new front primary sprocket and bolt/washer to hold it on. The new style sprocket may give you a better surface and mounting holes to bolt on a supercharger drive unit. As far as the primary cover, you will have to modify that anyways to hold the support bearing and shaft, so why not just include the necessary clearance for the new drive components too.
Primary cover is currently at the machining shop. I will call them tomorrow if it's been allready done.
When I got that cover in my hands I will recheck my measurements for the drive shafts length by intalling charger, primary cover and the bearings housing at their place. Then I'll have to get back to the machining shop where they machine that axle to the right size. At the same time I will make changes to the primary cover if it's needed.

Orderer that 2008 Buells CONNECTING RODS ASSEMBLY.
I have to consider those Carrillos rods too at some point in the future....
Next on my "To Buy List" is a forget pistons, that primarys front sprocket and nut for 2008 XB's crank, and CLUTCH!
My superchargers bearings and seals needs some little refreshing too. I still need those rotors back needle bearings, they are really pain in the ass to find. Only place where I could found them was at JonBondPerformances webshop.
Those tiny pieces of metal is worth 80$ ! With taxes and shipping cost to Finland I can multiple it by 2.
Hopefully I found those rotors seals at Finland, they did cost around 137$(2 shaft seals).
Rotors front rollerbearings is 6203, and not so hard to find. There is some differences at the clearances though.

I may have misunderstood your post above but did you say you ordered the 2008 connecting rods only? The 2008-2010 connecting rods will not fit on a 2003-2007 crankshaft. You need an entire 2008-2010 crankshaft if you want to upgrade.
The 2008-2010 crankshaft uses a bolt to hold on the primary sprocket and not a nut like the earlier cranks.
You can easily upgrade the XB clutch to handle the power you expect to see. Buy Barnett's Carbon fiber clutch plate set, 306-30-20015, and Rivera-Primo's Competition Gold clutch spring, 2059-0002. Trust me when I say it will handle your ~160hp.

HARLEY BUELL XB 12 XR1200R FLYWHEEL CONNECTING RODS ASSEMBLY 23999-08
On my understanding it's a crankshaft + connection rods. And I really hope it iiissssssssssss........!!!
A bolt! That explains a lot then!
I've been considering that clutch setup also.

You should be set with that crankshaft. Just make sure everything checks out on it before you put it in. Do you have experience checking H-D style cranks or know anyone who does?
I have a complete upgraded XB clutch assembly with Alto Carbonite plates and the RIvera gold spring I am trying to sell. Any interest in it? I'm asking $250 +shipping for the whole thing. Here is a link: Clutch for sale

Not so much experience on the bottom ends. I know some people at one Finnish HD/Buell shop, and probaply going to take my engine and parts there to rebuild. Thinking of getting bigger valves and my heads ported at the same time also.
Yeah, i'm pretty interrested for that clutch of yours, but will have to wait for the next month if you still got it. [up]

sounds like an epic build.

I've been thinking one idea a lot lately... And that is to build separate throttle bodies.... or not.
It's to build independent intake pipes to the oval, or oval twin throttle body.
Quick paint pic to tell the story better, cause my english is not so great to give the perfect picture.

I have been thinking the same thing! I bought a Lincoln throttle body like that to try. I have not yet figured out how to route the intake between the TB and cylinder heads so both runners have a smooth path.
It would eliminate a bunch of tuning issues and allow the engine to make much more power if designed properly!

In my opinion it's to give both cylinders the same air filling. And I think stock intakes are too close to each other. It messes with their air filling/flow or something.
Harley's have one connection rod pin, so front piston is coming right after rears. Front cylinder is only getting amount of air filling that's "left". Because of that it would be highly recommend to have big plenum on turbo HD's, so there is some air at the reserve to front cylinder to suck. I think that explaines also a stock Buells air filter and air filter box design.
On 1200cc HD motor 2.2 L plenum would be optimal.

Thanks that makes perfect sense. I didn't know that about the connecting rod. I would have assumed the front and rear rods were 180 degrees apart on the crank. So what you're saying is the front piston follows just after the rear piston and the rear sucks in all the air and there is not a lot left for the front? So increasing the intake volume allows more air to be left over to fight this problem?
Would this mean the front cylinder is likely to run rich?

Yes, front cylinder runs richer and HOTTER than rear.
