That’s the only difference - the relationship between a leak and pressure loss is related to tire volume.
The relationship between pressure and temp is not.
What did you do in your garage today..?
- Thread starter Hack
- Start date
The relationship between pressure and temp is not.
So what was it that I wrote that you disagreed with exactly?
Seems like GreyGhost said pretty much what I did, only he quantified what I qualified?
Looks to me like you disagreed with what I said, while agreeing with GG saying the same thing as me lol

Not really.
You said “Being so tiny, vespa tires are way more sensitive to temperatures cooling when it comes to losing pressure.”
I disagree with this. All tires change the same pressure as temps fluctuate, approx .5psi for every 5C change.
If your tires are leaky, that’s a different ball game all together. A leak of 100cc per day will most certainly impact a small tire faster than a big one. That has almost nothing to do with temp changes.

Right... but why are you stopping there like everything else is equal? Keep going with it. Walk with me here lol
Bigger tires generally = bigger PSI
Smaller tires generally = smaller PSI
Tire psi specs on my F150 are over 50% more than on my Vespa's front tire spec.
So if both vehicles have lost 3 psi over the past few weeks as temperatures cool, you're going to feel that more on the smaller tire, because proportionately, it IS more.
Because 3 out of 26 psi is more than 3 out of 40. And when you lose 3 psi in the truck, or a bigger motorcycle, it still probably has psi in the 30s, but when you lose 3 psi in the Vespa, it only has 23 psi in the front wheel and the small tires handles like a drunken donkey at 23 psi. So like I said, Vespa tires are way more sensitive to temperatures cooling when it comes to losing pressure...
Have had two bikes for a while now. Didn't really intend to, but selling one of them has been a low priority, and sometimes it is handy to have a "spare".
Struck out on both of them today though. TL1000S rear tire is totally flat, and 919 wouldn't start (suspicious of the tiny battery... again). At least the puncture is in the middle of the tread.

Wouldn't have been an issue if you had a third bike.
Or a fourth...
Not puttin' ideas in yer head or anything... Just sayin'...
*cough*
I suppose the two are both spares to the third bike, a ZX-11 that hasn't run in... some years.
Anywho! The 919 got going after only a little charger therapy, but gonna hafta investigate that a little further. Will charge it up fully over the weekend and see about getting it tested next week. And find out who in my neighbourhood is willing to patch motorcycle tires

Steering bearings on the Guzzi. The original ones were set way too tight from the factory, and feeling a little notchy. They're a cheap cage bearing and two part race, about as crappy as could be. I replaced with a tapered roller bearing set.
Life's better with a center stand:
The socket used to get the top triple off:
Here's a shot of the original bearings ( I cut the race to use as a driver later, so pay no attention to that).
I was going to pound out the old races with a punch, but there's so little to grab on to, I couldn't get any purchase. I bought a cheap tool from Amazon for all of thirteen bucks, and it had 'em out in no time. So easy!
I used an old race and a socket to drive the new races in.
The lower bearing on the steering stem gave me the most trouble. There are many ways to go about this, and many ways for me to screw it up. I chose not to be a hero, and took it to Ken in Whitby. Quick and simple for him, of course.
So, a relatively straightforward task. If you have some tools and a little know how, this is a good DIY job.
Have I ever mentioned how easy and satisfying it is to work on the Guzzi?

I am always in awe of the experience, and know how in these pages.
So awesome to see people be able to feel a problem, diagnose it, and then repair it in their own garage without spending oodles of money on mechanics and shops.
Kudos!

Finally got my Multistrada back on the road after a long adventure with a seized bolt. After all that, actually getting the wheel off was trouble free (though I'm surprised I was able to locate the parts I had removed months ago). Called Frank at New to You Tire in Barrie (somebody here recommended him), he said come on down and a 40-min drive from Orillia and a 5-min wait later, and new tire was on.
A few years ago I bought a set of about 50 bearing/bushing drivers. I appreciate the guys who can figure out clever ways to do things, but is it ever nice to have a full set to choose from and not have to make a run to CT for *something*. Made getting the axle off easy.
I had broken the arm on my mirror about a month ago while loading the bike into my shipping container, so I JB Welded it together and hoped for the best. Broke off again about 40 km north on Hwy 11. Although I'm sure it was trashed, I rode back a few times trying to find it, but couldn't. I think I'm going to be looking for aftermarket options here.
Also received a new starter solenoid that claimed compatibility with my VF500F. Sadly, the connector from my bike doesn't quite fit the solenoid, owing to where the replacement manufacturer decided to put the fuse housing. I need to figure out whether I want to shave the connector to make it fit, rewire a new connector, or just return it and see if I can find something better. I'm leaning towards the latter out of laziness. I'm no good with soldering irons.

I thought you sold your Guzzi months ago.... but then I got in a car accident and got a concussion so everything in between is fuzzy. Did you have two or get a second one or ?
Sorry to hear of your accident; be well.
I sold my 2020 V85 and replaced it with a very low mileage, low priced '22.
I disected a 12 gage shot gun shell. After watching the gun powder burn I wondered how loud the primer would be without any gunpowder so I locked the end in the vise and hit it with the auto punch. WOW! Started to wonder if the cops would soon arrive.
Hoping to hook up a light on the DragWing (attach a flashlight or ??) in order to run into the dark tonight. Tonight is the last Test and Tune Friday night at St Thomas Dragway and I hope to get out.
About 3 weeks ago they shut me down about 8:45 (they run til 10) because I had no light - that was after snagging 8 passes.

I have a light for a mtb that would probably work but I'm too far so it's not worth the drive. Two pipe clamps and a flashlight should be solid enough.
flashlight for last minute but probably easier to order smoothing off off amazon
Something came over me and decided to put the wheel splash guards over the trailer wheels. Pain in the *** but overall worked out well.
Also added in bracing as the aluminum fatigues and snaps…ask me how I know…
