The 671 Build

[671M900]

Fcr's are the cycleworks kit, so it should have everything. Headers are already off, like in the pics. Where's a good place to get the gaskets?

I was told I'd have to fabricate an airbox to move the battery to fit the dyna coils, but is it really necessary? I guess they don't have the cycleworks bracket kit.

No ecu? Just cdi? Sweet.

The ca-cycleworks dynacoils kit used to fit fine until dyna changed the shape/size of the coils. You may still be able to fit the kit just fine without removing the airbox.

Some people (like me) do remove the airbox to put pod filters (K&N 1750 if I recall correctly) and build a battery box out of a sheet of aluminum. It's pretty well descibed on the ducati suite site.

CAVEAT: if you go from an closed airbox to pod filters you will need to re-jet the carbs. though you might not need to if you have an open airbox (i.e. the top part was cut off to expose the air filter).

To my understanding, isn't the keihin fcr41 kit already jetted for pod filters, as they include them with the kit?

What main jets are in the carbs?

155 mains

That's what came stock in mine.

The literature with the carbs said that they were jetted for a stock bike. Chris Kelly at Ca Cycleworks jets 'em to baseline a bit on the rich side to allow for pipe mods, etc from what I remember. He would have to make a judgement call not always knowing what his customers are going to do. He and his crew are very helpful.
Give him a call to see what he would suggest for pods or open air box. His jets are very affordable and he is a true believer for the marque like most of us on the forum.

155s may be ok in your part of the world but I ran 165s with pods, pistons and open air box and 170s with open air box, pistons and substantial porting. I think our fuel in Oz is a little different though.

I also feel that giving money to an accomplished dyno operator is a good investment. This is even more the case with testing main jets! Dyno testing is cheaper than speeding tickets and visits to the ER. Chris may have a good recommendation that saves you dyno time.

[671M900]

Makes sense, but why would the kit include the pod filters, but not have the appropriate jets?  Would it be better just to run the stock airbox till I get the right jets in?

Moving the bike to my garage tomorrow, waiting for the title before we do that.

Among the parts list, Termignioni slipons, Cyclecat triple trees, rearsets!!!, and clipons! New fuel pump, clutch master and slave! Nichols Bar sliders! lots of goodies with the bike. Haynes manuals, Desmo times upgrade and maintenance manual, and receipts! Woohoo!

It's an M900 Dark, lots of carbon fiber as well.

Even if the pods came with the FCRs from the vendor, they may or may not be jetted for them, depending on who the vendor is and what they were told. Did they come from Cal Cycleworks? If so there is a good chance they were jetted for that application. It's worth having the conversation. I would tend to run the stock air box unless you get information to the contrary. I would call/email Chris to find out his recommended baseline for pods, get the jets if needed, and save myself some spanner work.

As mentioned earlier, FCR's came from cycleworks, which includes the K&N Filters as part of the kit. Well, I'm a ways away from putting in the carbs anyways, so  I'll shoot Chris a quick email or a phone call and find out what's going on in the kit.

Cool.
Sorry I missed that (somehow). Will be interesting to see what he says.

Here's a question, from the oil cooler are two lines, apparently supposed to go to the carbs, that's what the previous owner told me. I was told that I'd just have to block off the lines, what do they do?

The lines aren't from the oil cooler, they are from the intake manifolds. They are vacuum lines. The FCR just don't use them. You can just cut them short and plug the end of the tube. Make sure you put a hose clamp on to keep the plug in place.

Are they just bundled to the oil cooler lines? They look like they come right out of the oil cooler and have banjo fittings on the end.

[koko64]

Are they braided lines to a banjo to each float bowl? If they are oil lines from the cooler to the float bowls, then they could be a carb heating kit that many claim are only marginally effective. You wont need them with the FCRs. I would get the original oil line kit as it's much tidier.
