I'm trying to decide whether to pull the trigger on a bike for sale.
What modifications can easily be done to an 850T to be similar to a T3? Or are they much more similar than I think? I know they're the same frame. I know the t3 has the newer brakes/braking system. I think there's changes to the engine too? but maybe those are a bit more involved?
-
T3 will have an oil filter inside the sump, most 850T will not.
Some 850T have dual front brake discs, all have a 2LS rear drum, the 850T has triple disc and one front and rear disc are linked.
Some changes to locations of electronics between the T and T3
T3 has removable steel side covers but no locking tool boxes.
Some differences to ignition switch and switch gear.
-
consider keeping the T as is or close to it, they are becoming cult like.. you can add a second disc to the front and change the M/C but retain the drum brake in rear. the T with oil filer will have 2 bolts through the bottom of sump, no filter has perimeter bolts only on the sump pan.

Yeah. The bidding on the one i wanted just went up out of my range. More popular than i thought. Gotta save more for thus little venture

Fixerated. :wink:

I've had both. Functionally, the biggest difference is the braking system. A second disc on a T or an EBC rotor with a 4 piston caliper is the way to go if you buy a 850T. T-3 has a beefier U-joint.
-
The T had a desirable instrument cluster, and some of them had a different rear end ratio from the T3. The T has a cleaner overall appearance, and makes a better V7 sport clone. The T3 has a better charging system, brakes, and some of them came with floorboards. The T3 has the lower rear end ratio, which some prefer.

There's a nice T in Texas right now for $2K.
The T also has tool boxes behind the locking side covers.
-
I don't think any Ts came from the factory with dual disks at the front. If you add a second disk in the front the stock master cylinder will actually work better.

The final drive parts are different, from the gearbox splines back to the bevel box. You can't just bolt a T3 swingarm onto a T frame without swapping out some internals.
Desirable bolt-in mods to a T are the upgraded T3 alternator and fork dampers. The single-rotor front brake can be improved a lot by switching to a 12mm master cylinder.

If you'd prefer a T3, why not just get one from the start? Doesn't seem like a big price difference, and from when I was shopping it seemed like the T3 was more plentiful than the 850T I wound up with. Nothing proved wrong with my chrome-lined cylinders, but to take the issue off the table completely if I were shopping again I'd look for a G5 (5psd version of the 1000 Convert).

Late 850T's had oil filter in sump just like T3. Major difference between models is brakes. My 850T had oil filter in sump but I moved filter outside the sump with a Harpers "Outsider". Very worthwhile mod IMO. The rear drum was quite effective and I increased effectiveness of single front disc by installing a 13 mm Brembo master cylinder, stainless line, and modern pads. These mods made front disc into a very effective single disc brake. Fully adequate for modern riding. So if I were looking for a 70's Tonti bike, I would not hesitate buying a T.

No need for dual front discs if you go for a smaller diameter master cylinder, modern pads and stainless line

Stock 850T uses a 38mm Brembo F08 caliper with the 15mm master. You can keep the 15mm master and get a better hydralic ratio (better than the 12mm master with the F08) by going to a 48mm F09 caliper.

Replace float, ride for 200k....

one more thing. it is my understanding that the T3 engine block has more webs than the T in order to strengthen it further. i think that's mentioned in Guzziology (my copy is not handy to check at the moment.)
-
Webbing is the same on my T as on my Mille, and I'd guess throughout the Tonti run -- I think the webbing change came early in the V7 Sport series, and certainly with the increase in power from the 750 engine to the 850 loops. Anyone have better info?

Guzzi kept adding webs during V700 production, through the Ambassdor, until the very late Ambassadors which were the same as the Eldo, V7 Sport and T. From what I've seen, then it stayed pretty much the same up until the late '80s/early '90s.

Epb, i'm finding the opposite actually. I'm finding no t3's, but 2 different t's popped up at same time, close to my budget.
Everybody's answered my main concern which, really, was whether or not I can switch out the brakes if that was the bike I got. Irrelevant now. Price shot up out of my current budget.
