Couple of questions V7 Stone

[oldbike54]

 Friend's 2013 V7 Stone  7000 miles. First , he had the dealer install Mistral shorty mufflers , left the DB killers in . He tells me the pipes appear to be turning more blue than before , anyone have the recommended map ? Second , and I witnessed this personally , the bevel box oil was changed aprox. 2500 miles ago , looks really milky and at proper level it is leaking just a bit . Anyone else having this issue ? Most of the other teething problems have been dealt with in good fashion by Brookside Cycle in Tulsa , and the bike is going back , just trying to gather some info .

 Thanks in advance guys . Geez , a whole post and no silliness from me  :o

Todd at Guzzitech can map it for him.  It has the MIU ECU, so Power Commander won't work.  I had the milky oil too in my bevel box, the V7 Classic.  I changed it and it's been fine ever since.  Don't know about it leaking, mine never did...
I know there is a resource on here, guzzidiag, for mapping as well.....

[Cal3Me]

you might get a mist of oil from the drive box around the breather on the top. Never had any milky mess in my classic though ..... ???

Map wise right now someone has to do it in person with the Rexer software meaning if you don't have it you need to get the bike or at least the throttle body/ECM assembly to someone who does.

Rear drive, I've heard occasional stories of them taking on water in late-model smallblocks (think Jay had one milky drain on the V7C), but I've not experienced it.

Can't say about leak.

How does the bike run with the current map?  Any flat spots, stalling, etc?  You can check the A/F to see if it's running really lean after the dealer has loaded the most recent map from Guzzi.   :+1 on the Rexxer map.  Redline in Yorktown, Virginia, can make a map but it's always best to put the bike on a dyno and get a custom map for that individual bike.  Just for grins call Dave Lillard at Redline to see if the Mistrals with Db killers really needs a custom map or if the normal Rexxer map will work.

As for the milky lube, I'd consider the possibility that the milky look is from condensation inside the pumpkin.  Change the oil and keep an eye on it for more water still in the unit.  The oil is cheap, the rear drive...not so cheap.

Has he power washed the bike?

I'd change that bevel box oil to some fresh.

I don't know if I would call it milky.    It was a medium grey color, almost like it had fine aluminum particulates in it.

My bad, I thought I'd remembered you saying you had a little moisture contamination....

[JeffOlson]

Aren't the blue pipes due to the secondary air injection system? On modern, pollution-controlled bikes, it pumps air into the exhaust, causing unturned fuel to be combusted in the exhaust system, causing super-heating of the exhaust headers.

If this were a Triumph Modern Classic, it would be easy to remove the SAI system and install a resistor to fool the ECU into thinking it was still there (thereby avoiding a check-engine light). Has this never been done with the V7?

There's no secondary air injection system, that system was predominantly used by Triumph (if it was used by another motorcycle manufacturer I'm unaware of it). As a matter of fact, I kinda wonder if they still use it on EFI Bonnies, my guess would be no.

The blue in this case is simply from the extreme lean exhaust mixtures used to meet EPA standards and resultantly high exhaust temps.

My '09 Triumph Scrambler with EFI did indeed have secondary air injection when delivered from the factory.... but not for long!  ;D

Thanks for the info - and for showing me that my guesses suck these days lol - I'm like 0 - 2 in 2 days...  :D

On my 2014 Thruxton, I removed the O2 sensors and the SAI system, plugged the holes, installed resistors, installed BC Predators, and re-mapped the ECU. Incredibly easy to do, at least on a Triumph!

No more bluing of the pipes, no more popping on deceleration... Just smooth power and awesome sound.
I was hoping I could do this to a V7R when I get one next year, but it sounds like Moto Guzzis are different.

[Kev m]

The biggest difference with Guzzis is the small aftermarket so solutions like that are slower to come.

Though for many models you can use free GuzziDiag software to remap the ECM.

However they haven't cracked the ECM used on the V7 yet.

Shops with REXXER software can do it, but you have to get the bike to them, or at least the ECM which, and this is different, includes the entire throttle body assembly on V7 models because the ECM is integrated with the throttle body.

That same integration prevents you from using piggy back solutions like a PC-V.

And there is some evidence that the ECM might be self adjusting enough to make inline O2 resisters a bad idea as the motor could eventually go rich enough to wash the cylinders clean of oil.

[JeffOlson]

^ That's very interesting info. Thanks!

[mwrenn]

Thanks guys . The bike is on its way to Brookside today , last warranty service we hope .
 Kev and Peter, supposedly runs fine , just turning the pipes more blue .Dunno .
 Mike , hmm , will ask about the pressure washing . The bevel box oil really did look wet .
 Anyway , the bike and owner will be at CV .

  Dusty

Hope he is there Friday, he can try out my V7C 4V, be fun to compare it to the 2V Stone.... ;-T

[mwrenn]

That is a generous offer  ;-T Yes Alfred and the V7 Stone should be there on Thursday through Sunday .

  Dusty

Awesome!  Fun times ahead:)

Jeff,  that's pretty much exactly what I did on my V7,  but it's got the "old" engine,  that's easier to modify.
