V85TT Mods Thread

[GTM®]

Anyone fit Todd’s full system on a V85 yet? I just got mine and looking for some pointers.

Hi Sam, once you remove the stock full system, loosely mount the headers, connect the Y-pipe, then loosely mount the muffler insuring that the system is centered and clears everything. Start from the motor, and tighten the headers, center and align the Y-pipe so that the muffler is correctly positioned, and tighten the muffler bolt. We just did a 2022 in house today, everything went smoothly.

Ok awesome, I have it all on and finger tight until those adapters come for the sensors. Any hints on getting those unplugged? I don’t want to be twisting the wires all around when I tighten them again.

Please see attached, the Guzzi kit 2S001325 includes all these parts. The right hand grip comes complete with a new throttle body and that's what needs calibrating. If it was just a case of fitting heated grips I would have done it myself. Although expensive compared to aftermarket kits and it requires fitting/calibrating by a dealer, the Guzzi kit is linked to the TFT display and left hand switch unit.

I've also attached the V85TT Heated Grips installation manual. See page 17: 'After assembling the kit it is necessary to proceed with a new learning operation of the right hand grip using the P.A.D.S. diagnostic tool'

Copied from the Teo Lamers website:

For those who love to travel in all seasons. They contribute to driving comfort, preventing the hands from becoming sore due to the cold. The intensity of the heat is adjustable on three levels managed directly by a button already installed on the V85TT handlebar. The activation of the heating system is visible through an icon on the TFT. -3 intensity levels -Handlebar button activated -Icon on TFT -Ride by wire compatible. Please be aware: The throttle has to be calibrated at an official Moto Guzzi dealer with the factory software after installation.​

I hope that clarifies things.

I have just fitted the OEM heated grips as I had a red URGENT SERVICE ALARM, bike in limp mode and was recovered by AA. Diagnosed as fault with throttle position sensor - no replacements available in the UK.
New grips have cleared the problem, all lights out, throttle is lighter and seems more responsive. No calibration was required - plug and play - what a result!

So are you saying you fitted OEM heated grips, and those caused a running issue, then you replaced them with another set and all was right again?

No, the bike had standard grips and just broke down without warning. Dealer diagnosed Throttle Position sensor fault but was unable to source one anywhere in UK. Heated grips haveTPS included so thought it worth a try and hey presto - back up and riding! No recalibration needed.

Heated grips have TPS included?

Say what? I don’t think so….

That makes absolutely no sense at all.

 

[Kevin.NZ]

Yea, that confused me too. Maybe the dealer replaced a faulty TPS then replaced the broken heated grips and billed him for one job?

 

[Vagrant]

The way I understand it the TPS is part of the throttle body and can't be replaced. But, there is a potentiometer in the throttle grip (part of its ridiculous cost) and that probably was the issue.

 

[badgeressex]

Yes it must be the potentiometer I meant. The error was that the ecu was not registering movements from the twist grip.

Yes, the OEM heated grips for the V85 (and various other fly-by-wire Piaggio bikes) are a complete replacement of the entire stock grips, which happen to include the TPS (or, as they like to call it now "throttle demand sensor"?). The fact that his is working just fine without a TPS reset is possible, but perhaps a bit lucky. Swapping out potentiometers and not doing the factory-prescribed reset seems a bit like gambling to me, but if you win, you win I guess.

(Part # 2D000095, btw)
(also btw, this sort of explains why installing OEM heated grips requires [usually?] a TPS reset, while aftermarket heated grips do not)

Welcome to the future! If this was an earlier EFI bike, you'd be absolutely right.

[badgeressex]

Yes definitely lucky! I was expecting to visit the dealer as I had been told the cruise control would not work but all seems fine, no warning lights or anything.

 

[jwtucker]

Its definitely something to keep an eye on, though. Any issues with throttle control may be too subtle to really notice at this point. Generally speaking, even bikes that have had no modifications may benefit from an occasional TPS reset as a part of basic maintenance. But glad you got it working at any rate, in a relatively pain-free manner!

Never worked on one before so this is nice to know. Thank You Very Much For The Information!

(Just another reason I hate that platform! LOL.)

I actually did notice some difference in height between the low and regular seat, and I IMMEDIATELY changed it back to the stock seat after just one ride with the low seat.

I hated the ergonomics of the seating position so I changed it back.

I can't flat foot with the stock seat but with the low seat I am able to flat foot with ease.

So if anyone wants to purchase a very very minimally used low seat, message me.

I lowered the seat height on the stock seat by removing the rubber bumpers under the seat and lowered it 3/4 of an inch and also had dealer install a 1 inch suspension lowering kit which gave me another inch; at 5’8” with 29 inch inseam I can just about flat foot now.

Hi; I just ordered a set of those Givi handguard extensions; being an old man with cold hands I thought I’d install these for cold-weather riding and then remove them in the summer; look pretty sharp too!

I have recently installed the Pyramid rear hugger on my V85TT. Hopefully, this series of pictures will prove useful to someone contemplating buying one or about to fit one.

As you would expect the instructions supplied with the hugger are more than adequate to complete the task. The rear wheel must be removed so you can access the two inner M8 bolts on the shaft drive housing. Pyramid recommend using a high quality T40 Torx key on these bolts. I used an extra-long T40 key manufactured in Germany by Stahlwille tools. Their hardened steel Torx keys have correctly formed ends and fit the Guzzi bolts perfectly.

The instructions state that the casing around the bolts must be heated for five minutes with a hot air gun to soften and release the thread lock applied on the production line.

Added 20th January 2021:
I used a cut down extra long allen key and Loctite 262 red when installing the new bolts. The torque figure for these bolts is 25NM.

Even though there is a fair amount of work involved to install the right-hand mounting bracket, I am pleased with the result. The hugger is solidly mounted with no flexing and there is more than enough clearance between the swing arm and tyre.

Thanks Chris ; This will be helpful when I decide to put one on my 2021 V85TT; just wondering if it was fairly easy to remove the wheel and brakes? Thanks again John

Im not Chris but installed that rear hugger on my 22 V85TT. Very well thought out design byMG for the brake/wheel. It is easy peasy to remove and install.

 

[fastlaners]

Thanks for the reply sorry about the name screwup; John

 

[Chris Jessop]

Bit late with my reply, but as John confirmed, removal and installation of the rear wheel is very easy.

Talking of Pyramid, we took delivery of their V85TT splash guard yesterday and I will fit it over the weekend. Pictures to follow, see PDF below.
