1981 Yamaha Seca 750
Picked up a 1981 Yamaha Seca 750 from a dude here in town for a mere $300.
Needs a new battery, clutch cable and carb boots. New carb boots came with
bike and has a practically brand new rear Challenger tire. ~17k miles. Not
a bad buy as far as I can tell.
81 Yamaha XJ750 Seca 0-80mph
It's a 81 Seca: K&N filter, Supertrapp Exhaust, Custom paint, Extra wide rear tire,
Aftermarket handlebars, and a ton of other stuff.
I have timed the 0-60 and it's really close to 4 seconds.
The video is supposed to end at 0:30 seconds, nothing happens after that so
just end it there.
How to sync carbs on a motorcycle
This video demonstrates the procedure to synchronize a carburetor on a 1977
Honda CB550. It is really important, especially for bikes of this vintage,
to synchronize your carbs at the beginning of every riding season or after
any repair or adjustment to the carbs. This bike still needs some work to
be road ready, but it has a lot of potential and is super cafe racer cool.
If you are attempting to do this procedure yourself and have any questions
before you start, feel free to let me know. That's the good thing about
Youtube, FREE INFORMATION FOR ALL!!!!!
EDIT: Here are a few edits I would like to make to this video after
watching it a couple of times.
1. Make sure your carb synch comes after everything else in a normal tune
up. This includes Valve clearances, cam chain tension, spark plug
gap/cleaning, point gap, ignition timing, air filter cleaning/replacement,
and all the air bleed screw settings should be checked.
2. Engine speed for a carb synch should be around 1500rpms if possible.
3. The adjuster screw lockdown nuts should always be re-tightened after
adjustment (I forgot to show it)
