Found me a summer project Sunday down in Dallas TX. All original except the missing headlight and signals. Had a windjammer on it and of course the stuff has been long gone. Gonna start disassembly after work tonight. Carbs were absolutely hideous. two of the three were salvageable but the middle ones gonna need replaced or I may MacGyver a temp float post..it was literally rotted off at the top.

I had a '77 from new and put about 50,000 miles on it. As most it was a good reliable bike when not abused. Boring but good. Suspension wasn't so great but after a few upgrades it handled pretty good. More ground clearance than most bikes of the day IIRC (after upgrades). Only issue was a sloppy primary chain that was pretty easy to change. 3 sets of points was PITA though.
 
I always thought those were cool looking bikes. Love the tail section, the shape of the tank, wheels, and the fact that it's a triple. Something a little different for you, Chuck. I, too, will look forward to you putting your touch on it.
 
Shes down to rolling chassis with engine in the frame right now. Gonna call it for the day and yank the engine tomorrow after work. Few more nights and it will be time to start sanding and redoing the frame.....and then.....
 
What's the plan, Chuck? Restoration, or modified..? Same color, or different. Enquiring minds need to know.
 
In always keep them as I find them Larry. Stock rebuild for her. RS Motorcycle paint has the Carmine Red kit and theres a place in the UK that has the decal sets. Been researching many things already.
 
I'm almost with you chuck, I usually like original too, for a museum it's a must. Other than that, if you can make the bike a "better piece", without changing the appearance, brakes, suspension, comfort, or performance, without changing the outside appearance, that'd be good too. eg. electronic ign., a little better shocks that look period correct, possibly a little more modern brakes that may fit without looking out of place, or at least drilled rotors (as drilled would be period correct within a year or so) I think I've read some newer 3 cyl. "Triumph" carbs. were good on the Yammy triples. You wouldn't even need to tell anyone, just enjoy the upgrades & keep it a secret. Just my opinion. Very cooool & different project, congrats.
 
I think the only things I would do if it were mine would be to sand blast and then color match the front fender, paint the back one satin black, and put a set of super bike bars on it..maybe a header. Other then that it looks cool just the way the factory made it.
 
So I have never kept track of time spent reconditioning bikes. i decided i was gonna keep track on this one just to see how long it takes me. So far I have disassembled the bike, cleaned and stripped the frame, battery box, swing arm, broke down and painted all 3 calipers, painted the foot peg, exhaust hangers. Still need to do rims and triple tree. Lots of nut and bolt cleaning and master cylinders and caliper rebuilds to do.

But so far this is whats been done in 13 1/2 total working hours.

Interesting but not surprising as the Yamaha carbs are pretty much a direct bolt on for the old original 750 Triumph triples. Only problem there is the frame tube is in the way for a proper air cleaner if I remember correctly.
 
Larry..its VHT Gloss Black Epoxy paint in a rattle can. Durability is excellent. Calipers and pad carriers are Duplicolor Caliper paint. Monday I will be doing the driver footpegs, triple tree, and rims. Also plan on using some Back To Black on the plastic bits to bring them back around a bit.
 
Orielleys didnt have Back To black so I got this Ultimate Black. Does about the same job. So heres todays 4 hours worth. Some chrome and plastic cleaning. Total of 17 1/2 hours into the projects as of now.
