Fixing a badly built/maintained V35V
« on: June 02, 2025, 01:27:53 PM »
Hey all, long time since I've been here.

So where none off you will remember me from is about 12years ago, I bought a small block (yeah I,know) V65, former Spanish Highway patrol. I was gonna fix it, but it ended up standing still for 10years. Untill I wanted to fix it again. I started working on it and got it out of the shed and into my garage. Realising I wasn't gonna ride this bike for a few more months. A bike that was in desperate need of new exhausts (Due to EU regulations), I started to look for options.


Now I hear you thinking, well it says V35C in the title and I'm talking about my V65. Well, that's were it gets interesting. I found a nice looking V35C with original and aftermarket exhaust. I figured, ride the V35 meanwhile fix the V65 and get it through inspection.
Well, the V35C wasn't in a bad state, but it was about to be. The previous mechanic left all kind of surprises. Like tyres in reverse, double exhaust gaskets, impropperly sercured electronics and cables with aditional freeplay eaters to get the most out of each cable.

So the V35C has become a project of her own.
I figured I would post a bit about it, maybe there are people that are willing to read my silly escapedes. Filled with frustration, weeks of no motivation and a few days I try to fix everything.

 :gotpics:Pics you may ask? I'll post them in reply to this.

So grab some  :popcorn: and enjoy the show

I can't get to the photo of when I bought her
But this is how she looks now




Yes she's a she, named after the previous owner Suzy, who passed away to cancer. I named the bike after her which brought her husband to tears.
And yes you could say I ride ... But let's not

This is while fitting the new exhausts.




The original ones were to quiet. The aftermarket trumpets were just straight through with a BD killer in, deafening.
These are megaphones with a quick baffle in and an extra dbkiller at the front. The one in the pick with sound deadening on has an inner diameter of about 35mm. The other one, that is now fitted, is around 25mm. The wool has been added after this picture.




And this is how the are lined up at the rear




Anyone that has any ideas on how to seal an exhaust, when 3 adaptors are to many and 2 are not enough?

if you're trying to seal up a small gap between two cylindrical spaces, you can cut a beer / soda can into rings. cheap diy shims

This is a great idea and since it's a Guzzi, I've bought some San Pellegrino cans.
However,
I took the final drive apart in to replace the final output seal, that has been leaking after the second time I rode it. Looks like it needs a special tool to take the inner race of the axle.
Since I don't have the ability to build my own special tools at home. And I don't want to spend hundreds on a tool for 1-(maybe 2)time use. I brought it to a Guzzi Specialst, but they are very busy at the moment.

So since the exhaust need to come off to take the rear axle out, Ive not yet refitted them.

I don't know if I'll have the time to change the engine and gearbox oil this weekend. That and the brakefluid still needs to replaced. And hopefully that will be about it for the project.
Sorry I din't respond or post about the set back of the final drive. I got very demotivated and I'm really looking forward to freeing up space so I con get the V65c rolling.

That looks similar to the super cheap silencers that I bought, originally for the Breva. They were far too loud as standard, for me/my neighbours.
I've driven out the internal mesh/grid (with a broom handle!) that seemed to do nothing apart from maybe, providing some back pressure. I've drilled out the rivets on the reverse cones and stuffed the insides with wadding, after trying in vain to quieten them with dB killers.
Like you, I didn't have much luck in getting the pipe reducers to be effective and ended up using car exhaust assembly paste to provide a better seal.

I've been thinking about this for a week or so but seeing your posts has inspired me/prompted me into doing something..
Off to measure up the silencers for the V50.  :smiley:

Thanks, never even thought about the tyre being wider. It's the same size as my V65, so I didn't think too much of it, but now that you mentioned I looked it up and you are right. Luckily the swingarm is wider than the normal V35 models, but that doesn't mean it's easy to get the wheel in and out.

The original silencers are too silent and it seems every other option is super loud. These cheap megaphone's are as I said, modified. I bought the new internals from Kickstarter.de, a German custom site. Look them up. They have 3 dampers for the megaphone exhaust. This is the second most quiet, but in a test of another german fellow, he and I found the most silent one to sound shallow and sharp. And there was no differnce between the 2 in dB. Thats why I added aditional dB-killers, which does seem to make it rideable without earplugs for up to half an hour.
I am gonna try to get the Mistal's for my V65, but that's another price range.

Let me know if you want productlinks to check it out. And I'll make a whole post about it including the video material

Hey Faab, I'm not sure what's happening with sealing the exhaust.
I've had similar problems with my V65 and I'm about to test a new gasket GU91113826 plus new Mikalor clamps.
I've stuffed two in series in each silencer.
That is for 38mm headers so it's too big for the V35.  Maybe you can search for a smaller version.

These are actually exactly what could help.
My headers are 38mm OD and the bent pipe has an ID of 45mm. So I might still need one spacer, but that's better than having leaks.
Good thing I need to order some parts
