socket wrench and a 10 mm socket. Lift the tank up and prop it open
using the support rod on the motorcycle's frame. Reach under the tank

bottom of the tank. Take note of hoses' locations before removing them

the fuel trapped within the float bowl to drain completely, then tighten
the drain screws.

Reinstall the float bowls and their gaskets onto the
carburetors. Tighten the float bowls' screws with a Phillips

carburetors through the left side of the frame. Push the carburetors
into the motor's intake manifolds. Tighten the intake manifolds' clamps
with a Phillips screwdriver.

What type engine oil does an 1988 cbr1000 take
You can use any oil that is JASO MA certified motorcycle oil. 10w-40 for cold climate/year round. 20w-50 for warm climate/touring. Automotive oils use different additives and may cause scoring in certain types of cam bearings. Do not use any oil that says " Energy Conserving " on the label . It will shorten the life of your wet clutch and transmission gears. If you choose Synthetic oils, they will help your bike run cooler and shift easier. Shell Rotella T ($12 a gallon ) and Rotella T Synthetic 15w-40 ($22 a gallon) are inexpensive JASO MA oils. You will need 4 quarts of oil, an aluminum drain plug washer, and a filter. Pour in 3.4 quarts , run the motor, and check the oil level . Top up as needed.
I have a 1988 cbr
By "not getting any fire" does this mean that she's not even attempting to turn over? Are you getting power when you turn the ignition key? If so move forward to the fuses for the starter and cpu. From there check the voltage on the starter and then look at your plugs/wires.

If your talking about the handle bar end, switch assembly, throttle tube, grip. Hard to find used parts, Look for a doner bike, part it out and send the rest to the bone yard. While your taking it apart, you're also reverse engineering and you'll have boxes of spare parts. Or new parts. I like Bike Bandit.com because they have parts diagrams like everyone, but, they show avalable parts and those that you can't get any more. Others don't show the difference. I hope it helps,

Clunks when starts rattles at low revs
There is three chains inside the engine that stretch due to high milage. One is for the starter, one for the cams, and one for the oil pump. I replaced these for a friends bike and it quieted it down.
CBR 1000 MECHANICAL PROBLEM
Hi,
First you must check if your oil lamp is working. Normally after you start your machine and it reaches the minimum pressure above 1 psi, the oil lamp Will light off.
So if you had a problem with your oil pump and it burned you’ll not have information about your lubrication system.
I think you have a problem with your oil pump.
When you open your motor check the color of the pieces when they are blue means that they work with high temperature.
This machine is a good one and if you drive normally it won’t fail.
Please check this and let me know.

What oil do i put
To change your oil you will need 4 quarts of oil, a
filter, and a new aluminum drain plug washer. You can reuse the old drain plug washer
if it has not been squished out of shape. Your
motorcycle comes from Honda usually with 10w-40 mineral base
motorcycle
oil. You can use
any oil that is JASO MA certified motorcycle oil. 10w-40 for cold
climate. 20w-50 for warm climate/touring. Car oils use different
additives and may cause scoring in certain types of cam bearings. Do not
use any oil that says " Energy Conserving " on the label .
It will shorten the life of your wet clutch and transmission gears. If
you choose Synthetic oils, they will help your bike run cooler and shift
easier. Pour in three quarts of oil and add enough from the fourth quart
to reach the high mark on the dip stick or inspection window. Make sure
the motorcycle is upright or on the center stand when checking the
level . You will probably need
3.1 to 3.4 quarts to hit the high mark. Run the motor for a minute or
two to fill the oil filter compartment with oil. Now recheck the oil
level and top up as needed. If you want to try an inexpensive full
synthetic oil that is JASO MA rated 15w-40 Shell Rotella T Synthetic
fits the bill at about $22 per gallon.
Cam chain rattle when engine is idling
This bike is well known for cam chain rattle, but it has an automatic tensioner so there are no adjustments. If the bike runs well just ride it. I have a friend that had his cam chain, tensioner and guides, and in less than a couple years it was making the same sounds. If the bike run rough then it is a possibility the chain has stretched and unless you are confident with timing issues take it to a pro.
