Millie power from falco engine

Message

Yellowperil · #1 Post by **Yellowperil** » Sun Apr 13, 2014 2:35 pm

Would anybody happen to know the differences between the Millie engine and the falco engine?
Is it possible to get Millie levels of power out of the falco engine or is it going to be easy in the long run to just fit a rsv engine?
Apart from engine are there other concerns to address if considering fitting a milie engine, are throttle bodies the same, is the exhaust still usable (from the falco), will the falco ecu still function effectively?

Thanks in advance

The engine fitting wise are the same.
The more powerful mille rotax has bigger valve heads. 2001-2005 That all

The ecu is the same but the chip is different.
The later gen 2 rsvr has a 4 bolt flange on the headers as the mille and the falco have three.
The earlier post 2001 mille engines are the same small valve engine to the falco

Original Mille and falco engines were the same small valve engine

The Mille had a different chip set up and exhaust
The very very early falco's had Mille injectors.... Mine is #72 and has the Mille injectors
Slight variation in airbox configuration

IF you wanted to change engines then get a big valve engine

The Gen2 engine (2004 onwards) will also fit but the electronics are different. It can be done and has been done .... but it's not simple.

Large valve/revised cam mille (2001? to 2003) will give you a bit more but probably not worth the hassle.

If you really need more power, talk to Griff about one of his 1060cc big bore kits.

I always thought the early Mille engines also had higher compression, although otherwise very similar.

iirc correct Howard - slightly different cam?

Ok, so on this basis, if I were to fit 03 Millie heads cams and exhaust plus change the chip (I have a forza currently) then that would equal Millie power?

I've looked at the 04+ engines but the up down and sideways of it is it realy worth it, I mean the 03 engine parts are cheap and the exhaust are a fair price but the 04 engine with all the necessary components to run it are worth a lot more than my bike!

You need a gen 1, late engine - 04 is likely a gen 2 Mille lump - or late registered gen 1

Tbh

Far better things to spend on - get the handling right, with shock, forks wheels etc....

Unless you are a track god, apologies but you will not benefit from an engine swop

If you are like the vast majority of us, getting the handling right is a far better option

I agree with pete. But that said I do have a later gen 1 engine in the garage to finish off a project?
I will look the engine code up on the engine and let you know what it is.

I know where your coming from, the handling is sweet and I like it just as it is, but power isn't quite up to keeping up with more modern super bikes!
I think the ride on the loaned Big Bang R1 put things in to perspective the other day!
I'm not after insane power but I'd like to see 155+ from time to time

You can't really compare a 1000cc v twin to a 1000cc inline 4. It's a completely different engine and design philosophy and each have their own characteristics.

A 1000cc v twin is more comparable to a 600cc inline 4.

As D-Rider has said, if you want a bit more power talk to Griff about a big bore kit. You won't notice much of a difference swapping cams or exhausts around.

What final ratio gearing are you running?

The bike won't pull full revs in top with standard gearing so you can pep the thing up for peanuts by swapping the front sprocket for a 15t item (down from 16t)

The other way is to add a couple of teeth to the rear sprocket (41t as standard) - but that requires a longer chain so is more expensive.

Not saying it'll give you all you want but if it hasn't already been done it'll help (and make it nicer to ride around town too).

I knew I'd get a bashing for that R1 quote

I'm not after inline performance as I'd just go and buy a honda civic
I'm after a bit more poke from a bike that I want to keep for a few years yet, so 01-03 onwards Millie heads etc and a ex system, right shopping list written!

Just a quick query, any idea what Black Magic cossworth cast upon the SP the give it more power than the same year milie?

D-rider thank you I shall do that ASAP, your quite right it doesn't top out in 6th, the most I've seen is 148 tbh and that's on a longish stretch!

My Falco hangs with a GEN 2 Factory without too much hassle. ALthough the tyres don't like it. I'm running Bridgestone BT021 awful things.

I have a Forza chip and SL Cans that's it.

I am going to change my gearing at chain and sprocket change time for a litle more acceleration.. 15/41 i'm going to go.

Best thing to do before ANY performance upgrades is sort the handling. These things are amazing when set up properly
