How To Rebuild a Motorcycle Shock (Dirt Bike Rear Shock Rebuild Video)
http://www.rockymountainatvmc.com This video will show you how to rebuild
the rear shock on your motorcycle or ATV. We show you how to change the
shock seal and oil inside the shock. Your Motorcycle shock needs to be
serviced on a regular basis, and we make it easy to do. The process is the
same for many ATV shocks and street bike shocks. Rocky Mountain ATV/MC
stocks the tools and parts you need to rebuild your motorcycle suspension
(forks and shock). In this video we rebuild a Kayaba Rear Shock but we also
demonstrate how to disassemble a Showa Shock as well. After performing this
rear suspension service you will need to fill the shock bladder with
nitrogen and this can be done by almost any local shop for a minimal fee.
Visit our website to see all the parts and accessories we carry for your
dirt bike, street bike, atv or side by side at Rocky Mountain ATV.com!

but typically that isn't required.
How a carburetor works, schemes and explanations
This video explains, not in too much detail, how a 28mm Walbro diaphragm
carburetor works (using mainly schemes to point out what happens inside).
It explains what occurs at the venturi, what the butterfly valve is for,
how the needle doses the amount of fuel, and how does the diaphragm slide
How to adjust the jets on motorcycle carburetors
This is a brief introduction to the fairly touchy process of re-jetting
your carbs. The techniques discussed here are fairly universal to most
carburated motorcycles, but not all, so your first step in performing carb
tuning should be to consult your repair manual and online forums. Hopefully
this video can demystify a lot of the process for you, so that you have the
courage and interest to do this yourself. Let me know if you have any
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)
