S4rs What Fits?

I removed the baffles on mine as I liked the look of the standard side swept ones.
It’s quite a tricky job but worth it.
It ran fine and sounded like a Ducati.

 

I gutted the cat on mine and was surprised how little difference it made to the sound.

 

Any dry clutch cover fits.
Any slipper up to even 1198 will fit as long as you use the smaller nut for the drum (STM provide both sizes)
Rear stand for any small hub (5 bolt Cush drive rather than 6)

 

Abba Skylift, at your age should you really be kneeling or bending down....

 

Re: "Short stubby Termi"

Is this what you mean?





If so, it comes with a baffle. As you can see, mine is de-catted (if it ever had a cat) and it is very loud without the baffle in.

It is designed to slip straight on to the outlets from the cat but if you get aftermarket or de-catted downpipes, then you will probably need an swaged adapter. I bought a couple off eBay but I had trouble getting one with the correct bore differential, so I ended up taking a blow torch to the inlets and then bashing the adapter in with a mallet so when they cooled down it was shrink fitted. I then brazed spring loops onto the Termi inlets because after having once run over my own underslung end can which fell off, I don't trust clamps.

The end can offered up to the bike, showing that the Term inlets are the same size pipe as the downpipes, and hence the need for an adapter.



Inside diameter of the Termi inlets. OD is 45mm.



Inlets fitted with the adapters. I had to heat the inlets and then bash the adapters in, but they're dead solid, plus I have also fitted loops for exhaust springs.




I bought it second hand along with a set of OE downpipes for a 'stretta engine like yours but as mine is an early R with the 996 Desmoquattro lump, they don't fit. If you want to try de-catting but don't fancy butchering your OE pipes, you are welcome to have mine for free if you can collect them from Herts.

Btw, if you are thinking of cafe'ing it as per your other thread, and you're going to change the tank as I did on my S4 special, you will probably need to lose the airbox and run cones instead. IIRC, I also had to swap the trumpets for shorter 916 Superbike items. Unfortunately, this has spoiled the fuelling and killed a bit of power, though it makes up for it by booming like a cannon and shooting a foot long blue flame out of the 3" bore end can on the overrun. A Power Commander might have sorted that out but tbh, I am a child, and I like the fireworks show, so I haven't bothered.

You will probably also need to relocate the battery and change it for a smaller unit. Mine has a custom made tray housing a little Panigale battery. If you want to see pics, let me know.

You might also run into clearance issues if your engine has the overhead injectors which I believe some of the later 998 engines have, but I may be talking nonsense as that was something I never fully explored because I ended up using an S4 as the donor bike. I've flagged it up just in case

 

The throttle bodies have the injectors in then, rather than being an overhead injector set up.

 

Also maybe worth a mention that the ST4s Ohlins unit is a virtual bolt in. I say virtual because you then need to mount the remote canister and adjuster. Do-able tho...

 

Regarding the slipper clutch, i fitted the EVR 48 tooth setup.
I originally ordered it with sintered plates. It worked great, but the steel plates hammered the Sh$t out of the basket. Changed the plates to organic ally versions along with a new basket.

I find the "old" Monsters are set up a bit low at the back/high at the front which makes them a little lazy, so I've dropped the forks on all the ones I have ever had and will do it on my S4R when I get round to it.

I'm sure you are better at setting a bike up than I am Paul, so I hope that isn't teaching you to suck eggs!

 

I fitted a DID zxm 525 chain, JT 15t front sprocket and a Supersprox 43t rear.
