Intec System???what is it??

just found this ...has anybody heard of it...:dunno

No mate if it in mcn it must be ****

Originally produced and supplied by Harris as far as I know. I don't think they still supply them. I remember at the time there was quite some debate over their effectiveness. A contentious subject to say the least as I recall.

Sorry, that's not much help is it :lol

if they were that good i'm sure more people would know about...sounds a little iffy to me

I had one fitted to my old duke 748. What it basically does is allow you to fine tune your engine braking. when rolling off the throttle my 748 was like a two stroke. I still have it sitting in the garage after I sold the bike.

i love the engine braking..lol...so would you say its a worthwhile addition? were you impressed..?? why havent you fitted it to your mille?

There is (was) a video knocking around of Neevesy from More Crap Nonsense getting one of these fitted to his Gixxer1000 along with one of their GP type exhaust systems.

Very interesting it was to,before and after dyno sessions then blank off the Intec and fit the exhaust ,dyno again,roadtest then unblank the intec and roadtest and dyno them both together.

If I recall correctly the Gixxer was one of the weedy ' 07's and it gave it back the brutality of the 04/5. Neevesy reckoned the mods turned it into a race bike.

The intec worked by doing something like bleeding crankcase compression into the airbox ??? was worth a couple of dyno proveable BHP on the Gixxer,how much use it would be on a twin is anyones guess.

and here is a comment from the Gixxer forum

Having watched all the videos and read the patent description. I personally wouldn't fit such a valve without further modifications.


The theory on the emission reduction is to add extra air to the inlet in effect leaning off the fuel air mixture. this while cleaning up the burn also causes an increase in combustion temperatures, which under prolonged use can cause hotspots in the combustion chamber, increasing the chance of holing pistons under conditions of hard use. "racing"


The Bhp increase show on the dyno, wouldn't be noticed on the road. Due to the way dynometers measure horsepower. During measuring the engine is left to slow in gear the theory is to measure power loss through the drive train. So the crank bhp can be calculated. By fitting the valve engine braking is reduced by the valve releasing vacuum on the combustion chamber. thus reducing the engine braking effect allowing the engine to slow more gradually. the dyno would read this as a reduction in power loss through the drive train. Giving a false reading of crank bhp.

You pays yer money ...............................................

i've got it now...so a complete load of crap then..my suspicions were right ..ok if you want to play with the engine braking levels but no good for real power increase,,,,

One of the motorcycle mags, P.B or somesuch did a test as they thought MCN were talking bollocks about it at the time. If I remember correctly the bike they tested it on lost about 4BHP everywhere and upset the vacuum levels quite badly.

Given that the APE uses vacuum to operate the back torque limiting clutch I would think this to be potentially a bad thing.:dunno

Here's some more reading from the Ducati forum

post # 60 is relevent to us,seems it was sold for RSV's in the past.

I have to say that I'm definitely unimpressed by the Apes vacuum operated torque limiting device,the Sv1000 has a far better mechanical system IMHO .

And yes,it is working as it should. Adjustable action would be quite nice I would imagine.
