77 Yammy XS 750 Triple

Painted the tree, rotors, and rims today. Broke down shocks and started rehabbing them. Pics to be posted tomorrow at some point.
 
Those are awesome bikes, great looking, mean sounding, and great torque range for a street ridden bike!

The big downfall of them however is the transmission. The gearboxes dont take a ton of abuse. I think it may be 2nd and 3rd gears in particular, but I can't recall for certain. Information is widely available online on which areas to inspect thoroughly on a disassembly.

Very cool bike, great looker...
 
Yamaha had 2nd gear problems for yrs. & yrs. & yrs. Chuck, you're always pretty much up on this stuff, but are you sure just swapping around some washers would have fixed it?
 
Great info to know right there! I occasionally bring up those bikes when friends are shopping for a good vintage street bike...
 
It jumps out because the dogs werent long enough to lock up with the gear. By taking the back washer out and putting both in front it sets the gear back in and lets the dogs grab better. Some folks even had the rear of the gear milled a little for even more grip.
 
Got the engine painted today and finish the rims and rotors...but left the camera at the shop so I will download pics tomorrow at some point. 25 hours into the rebuild and thats from the time I started removing the tank to it being near ready to be reassembled. I should come in under 40 total hours. At least thats my perdicition anyway.
 
Used a wire wheel in a Dremel to clean the leading edges of the spokes and wet sanded the beads with 600 grit. Cleaned everything up and painted the rims. Theres one done next to an untouched one. Pretty big difference.

Those Continental tires were the $h-t back in the day. Nice progress in less then 40 hrs. of work, Chuck.
 
Larry, I posted in TIPS AND TRICKS asking for suggestions on a hard core paint remover. Whatever they used on this lump laughs at Home Depot paint stripper.
 
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.

My brother had carbs off of an H1 on his '69 Trident. He never got it quite right, but it was pretty quick for its time.
 
I had a ‘79. Handled squirrelly, but had nice torque. 2nd year did go out, but after I gave it to friend with 82K miles.
 
Went to the scrap yard Saturday and picked up a headlight assembly, front signals, and a rack of carbs off a 78 model. Got the carbs rebuilt and the rest of the front end installed. Took pics but now it seems the USB cord for the camera to hook to the laptop has gone bad. I will update with pics sometime this week. Got very near 40 hours into it now.
 
Well the rack of carbs from the scrap yard needed new pilot jets but we did fire the engine up Sunday afternoon for the first time in around 21 years or so. Fiddled a bit with the mixture screws and got it close except the richness at idle. Got new stock pilots today and they seem to have remedied the situation.

So it was on to hooking up the signals from the scrap yard and function checking everything. Had to tear down the left hand switch and resolder the wires to the switch and got that all sorted. Next its time to clean the right hand switches and get to Best Buy and get that USB cord for my camera so I can post pics and videos.
