Need someone with an evo

[Ron1000]

Guys,
Can someone with a monster 696, 796, 1100, 1100evo(preferable) have a look at their servo unit and send me pictures of the bolts and any rubbers that are used.

I've taken mines out and now cant put it back together, it looks to me that either I've lost a some sort of rubber spacer or the previous owner has removed and put it back with different bolts, rubber spacers etc.

Any help is appreciated guys.
Thanks.

Hi, Ron

I removed my servo last year and took a couple of photos in case I forgot how to refit it! (Ignore the cable tie, that was just to stop it vibrating.) The forward nut has been removed in the photos.





There are two bonded rubber vibration dampers; one goes under the mounting bracket, the other on top.







If you need replacements, these are the part numbers...



Hope that helps.

Thanks Luddite,

Yeah mines is different to that, I have silver Allen heads without the large flange and as I suspected I'm missing a rubber dampers is missing. I've hunted the shed (which is pretty clean) and I cant see it.

Suspect this has been played with outside of my ownership.

I can get the top one to fit on no problems but it vibrates around way too much for my liking so I'm going to have to come up with a plan for fitting it some how......potentially tie wraps would work.

This has came about due to me attempting to a valve bypass from SmartMoto....anybody had any experience with these? I fitted it (2min plug in job) and tested it and this happened:

1. EMI on with bypass plug if valve self check carried out.
2. EMI off with bypass plug if valve self check not carried out (I believe it does not go through the self check in certain circumstances....possibly when warmed up.

3. EMI on with servo if valve check carried out and I did not re-attached the cable.
4. EMI off with servo even if valve check carried if I put it back together as per factory.

So I'm thinking if I can reliably replicate step 2, I may just run with the bypass plug.

Any thoughts? does anybody have EMI issues with the valve removed or is there a smarter way to do it.

Thanks guys.

Not sure if it's a smarter way, but I have a DUC.ee you can have for a donation to UKMOC slush fund.

If you want it, PM me your address and ill stick it in the post some time next week

[Evostu]

Newish evo owner ..so what does duc.ee actually do?

[Luddite]

The duc.ee unit is designed to fool the ECU into thinking that the exhaust servo is still connected. If you have the DP Termignoni ECU that also disables the servo.

Alternatively, you could have the standard ECU reflashed by Neil at Cornerspeed (01623 238944), which will disable the servo (and the lambda sensors too).

Ron, before you try your own solution, give Craig and Luke a ring at Moto Rapido (01962 873981) and see how much replacements would cost. They could probably get them to you within the week.

[Ron1000]

Thanks jonzin & luddite.

I'll have a better look tonight. Yesterday i was tight for time and hungry so never a good combination.

I get back to yous later.

On a kind of side note, my bike has a pcv fitted. Can you bypass the valve (and o2's) via that?

The Power Commander only adjusts the fuelling, it can't disable the lambdas or servo. In fact, if your O2 sensors are still enabled, then the Power Commander will only be effective above about 5,000 rpm and/or higher throttle openings. At lower revs/throttle openings, the fuel system is "closed loop" and so the lambdas will effectively cancel out any adjustments made by the Power Commander.

You could try some O2 eliminators but be aware that I don't think they work on the final year's Evo. I used some on my 2011 model before getting a full remap and they were quite effective. Certainly the CEL light didn't come on at all.

[Ron1000]

Luddite,
I've got lambda bypass, yeah they don't work with mine (final year) or at least not fully. I had a run with them on and they kind of intermittently turmed the emi on and off.

They are free to a good home or swap with jonzi / donation to ukmoc

[Luddite]

It looks like your only option for disabling the lambdas is via the ECU. You could ask Neil at Cornerspeed if he could turn off the sensors without carrying out a full remap. CJS Racing in Bristol (07517 490213) can also turn off the lambdas but I don't know if they offer a postal service like Neil does.

I'd definitely try to bypass the sensors, otherwise you're not getting the full benefit of your Power Commander.

[Ron1000]

Roght servo refitted. Little bit of a 'workaround'. It it's in place and solid now.

[Tim88]

I have had a Healtech exhaust valve eliminator fitted for a few months now with no problems. I have had my doubts about whether there is any point to this mod but on balance I am happy to have gained the extra space under the seat for my Inforad speed camera warning gubbins and the improvement in low revs exhaust note. If I try hard I can also half believe that the engine is smoother through the rev range where the valve would have been operating. Evo has just had a large-ish service at Snell's and I don't think there were any error codes to be reset. Did you really have to refit this ridiculous valve? if you did has it fixed your issues? Would be interested in how all your modifications work out.

[Ron1000]

Yep just got the servo refitted. All working well, the smartmoto eliminator does not work on a 2013 evo.

Jonzi is sorting me out with a duc ee one so i'll let yous know how that goes.

Yeah i only wanted the servo and cables gone as a tidy up type thing rather than as a performance mod. Hopefully I'll get there in the end with the servo.

Looks like o2's I'll need to live with at least for the moment.

The biggest mod I suppose is the pcv, low revs it's insane how better it is i can ride through villages at 10 miles per hour without hunting, surging or snatching and not having to use the clutch. Can even ride through town one handed it's that smooth. And it feels like it pulls harder medium to top end.

The fact that your Evo is running so sweetly low down suggests that your O2 sensors may already have been disabled.

When I had a Power Commander on my S2R, it had no effect low down until I disabled the lambdas. In fact, I found this FAQ on the Dynojet site:

"Do I need to disconnect my o2 sensors?
In order for the race ready line of Power Commanders to have complete control over everywhere a vehicle runs, we usually want to disable, or control the stock o2 sensor(s) on a machine. This gives us the ability to tune the vehicle everywhere. If the stock o2 sensors are left connected as from the factory, they would conflict with the fuel changes the Power Commander is making. In effect, nullifying the fuel changes the Power Commander makes."

Perhaps your PCV has the Autotune unit, which uses wideband lambdas to adjust the fuelling?

Whatever the reasons, you've found the holy grail of smooth low speed running and I'd leave things as they are now and just enjoy it!

[Ron1000]

They definitely throw up an error if I unplug them, whether or not the ecu or pcv handles them differently somehow i have no idea.
