Nothing gets by a good wife!
Just a thought you riders down south don’t know how good you have it. Up here in New Hampshire we are lucky to get a ride in April 15
Good luck hope 2025 is everything you hope it should be

Spent the morning starting the rebuild and cleaning carburetors. Never seen the inside of a carburetor but u tube and manual giving it a shot. With any luck this 1980 750 will come back to life . If not I will send it to a shop lol

I rebuilt my first set of quad carbs for an old Yamaha with Youtube, the Haynes manual and a lots of previous forum posts. Cleaning is the hardest and most important part, then, there's the synching of the carbs which I haven't quite mastered. Good luck!

Thanks but I seem to have a rattle after reassembling #4 thought it might be the needle from top puck don’t know. I will probably open it up again to figure it out lol

I tend to disassemble and reassemble parts three times (not on purpose) before I figure out what I missed.

Upgraded my starter clutch using a CB900 flange and Yamaha R6 bearing. Definitely sounds better when I hit the starter, and sounds more consistent.

Sounds like MacGyver

Pulled the carbs off my 72 K2 to replace the inlet hoses.. what a b^&%d of a job!! They're back on, but not 100% happy, so thinking they'll come off again for a second try..

Good luck sir hope it goes well.
I’ve been working on these the last two weekends
Happy new year

Wow! Those look like they've done a few miles

I pulled the bowls off mine, and they were good.. couple of idle jets were partially blocked, but easily fixed..

I'm sure with some TLC yours will come up great again!

This barn find has not been registered since 2011. Paid less than 200 for it did compression test (about 128) not bad next sprayed starting fluid and it ran. I am attempting the carb cleaning and rebuild worst case scenario I will send to shop to get done. Fortunately no major rush for this project I also own a 82 xj650 I drive daily (when the weather allows)
