V7 Stone 2014 Clutch issues

Hi Everyone,

I've read all the forums about the V7 clutch issues when the engine heats up that I can find and tried them all so far but now stumped on what the cause is and what to do next. Any help would be very much appreciated.
---
The Issue:
I've got a V7 Stone 2014 which is now around 17,000 miles. Up until recently (15,000 miles) I've had no issues with the clutch.

Now when the bike gets hot it doesn't work and the gear selection grinds or even doesn't go in. This happens with the clutch lever pulled all the way to the handle bar grip.

The issue is worst when riding in traffic, but also happens after motorway riding (I think the heat of the engine is key to the issue starting). When waiting at lights I ensure I go into neutral early, so I'm not sitting there holding the clutch in. When hot I also have to whind out the adjustment on handle bar lever as the 2mm gap increase to somewhere between 10-15mm in the heat and clutch stops working properly.
---
Steps I've taken:
1) I've zip tied the clutch cable away so not resting on the engine
2) I've installed a brand new clutch cable
3) I've taken to the dealer to adjust the rear gearbox lever
4) I've replaced the clutch's: rod, thrust bearing, inner body, spring, o-ring, inner body and given the rod a bit of high temp grease to allow it to slide easily
5) Forums say the rear lever adjustment is fiddly so I've tried in about 10 different positions. Before every ride undoing lock-screw then moving the adjuster screw a quarter turn and trying. Then...checking all other settings are correct: Handle bar leaver 2mm gap, there is play in the cable at rear lever and that the end lug rotates/moves freely.
6) Throughout step (5) I am confident the rear clutch lever has been set at 90 to the rod pushing the clutch plates
6) I've also checked the splines of the gear selector and gear lever to ensure there's no play there affecting the gear selection when clutch isn't working as well.
7) I've also checked my bike frame number wasn't one that was recalled due to having a missing bearing...but the sound of that email thread makes me think it would never have made it to 17,000 ml alive if that was the issue.
---
I'm not sure what to do next, and a bit nervous about taking the clutch off to investigate without a plan? I see in the forums I've read there's a huge amount of knowledge and experience taking Guzzi's apart here so hoping someone will be able to help?

I've also added some pics as thought it would be helpful.

Hi @john zibell ,

Unfortunately the bearing didn't solve the problem. I did account for all the rollers before putting together too.

I really thought it would be the solution and want to avoid taking the clutch out entirely. Although it would be a good challenge crabbing the frame I'd need more tools, improved set-up, and an extra pair of hands.

in my research so far the hot clutch disengement issue is keeping me looking at the rod, thrust bearings, actuator arm and adjustment. I only see the issues that need solving by removng the whole clutch so far being clutch slip. Or the faulty engines with crank baring issues with given the miles ive put on confident is not my issue.

I'm still learning a lot from all the good contributions people have on here so feel free to correct any assumptions about clutch disengement issues happening deeper within the clutch plate area.

Thanks,
Jimmy

Hi, I'm not sure it's fixed yet. It require a lot of persistence and paitences with the penetrative oil but was rewarded by recently managing to get the pin from the gearbox end clutch lever out. It was frozen with rust. Seems to have some improvement but only ridden once since for a short time. That ride felt better but still not convinced its fixed...might just be that I've lost hope a bit though. To be honest, I've grown to not like the bike and would sell if I didn't feel bad for selling on a dud.

When I test it a bit more on a longer ride I'll let you know the result.
 
Seems you may have isolated it down. I would say don't loose heart (easy for me to say). This is my 1st MG and can say it's a Love/Hate relationship. Love the design, Hate the Italian traits, ( poor dealership support, poor parts supply, quality hit or miss, service manuals written in French/Italian/German). The Plus is the perfect mechanical design and "Italian styling " which Italians are Masters at ( My wife is 100% North Italian). Thanks for the update.

Thanks @Howardhughes. Yes, hopefully its the last puzzle piece and I'm back enjoying longer trips again. Either way I'll notify this thread about whether it was a fix.
