Well I think I finally found a suitable project a 78 t3
benebob:
After recovering a few years from the bad taste my 16 v7 left in my mouth and a far too ambitions first guzzi rebuild to start with in a v700 I drug this old gal home (a 78 t3) this past week. Judging by the tires I doubt it has done much road duty for 25 years or so but it she does run, go and stop (though I wanna at least check the barrels before doing any of that stuff and do plan on replacing 'em as soon as I get everything else up to snuff.
I know I will be in the market for at least the following parts wise. The front turn signals and bracket as apparently they don't mount to the ears. Headlight bucket, taillight and turns and maybe some more correct silencers.
In the meantime I got tires on order, and will order all the bits to do a full fluid change this week. Plenty to of things to do while I wait for parts on the other project that appeared in the trailer this month a 48 Norton es2.
I do have one question to start with. The switch gear is pretty bastardized. The left switch has wires soldered to the switch, the right is non existent, no keyed ignition and a push button for the starter. I would like to go with a japanese or maybe a modern triumph switch set up. Are there any that are more suited to an 850i then others?

Your front forks (at least the sliders) are later, probably from an SP. The front fender would have been a stainless one with braces mounting it to the fork.
The signals did mount to the headlight/ears originally. What's wrong with your headlight bucket? Perhaps it's just missing the thick rubber seal between the rim and bucket?
I have a pair of nice original mufflers (and header pipes as well).
Greg Bender sells a few different switches - vintage Yamaha style and modern Domino. I've been using K&S switches on my Convert and have a few spares of those.

I'll be parting out a '76 850-T3 if there's anything else you need.

Good catch eagle eye Charlie on the forks and fender which is plastic. I suspect the ears may be of an sp as well as no holes.
Headlight doesn't fit well and is slightly bent. Haven't pulled it to look yet plus the bucket has some poor repairs.
Yeah that complete exhaust may be up my alley. Will need rear pegs as well at the very least so far.
Would love to find a period correct switch set that lets me turn the lights off if I can.
Got the bits on the way to do a full fluid change probably first since Ollie was selling guns to Iran. she does run rather well though all things considering.

The signal stalks thread into the headlight shell at the mounting bolt holes.
I have a NOS headlight, but It's worth as much as some complete bikes. :wink: Mark @ Moto Guzzi Classics might have a good bucket. I think I sold my last good one.
Greg Bender sells a replica of the '70s Yamaha switch, and there are repros for Kawasaki Z1s available as well. Not terribly difficult to wire in.
I don't have a crossover (already sold that) but do have header pipes and mufflers.

Okay first dumb series of questions. Having read the clymer 850 section on forks i am confused as to what needs to be done to do a fluid swap as it seems they want ya to disassemble the whole
Fork and 1/2 the front end. To drain and refill
I just need to remove the hex bolt on the center on the top guessing 32mm nut then take the 32mm nut off turn upside down to drain then refill? As Charlie said these are probably sp forks
Do they get atf as well and how much should each get?
