Starting bike; Bike won't turn over

My battery is good but when I push my starter button the starts wing turn over. I want to know if it can be a relay or the starter itself. I can push and then pop start the bike then it is fine. I also need to know haw hard it is to change the starter if that is what it is. I do most of my own mechanical stuff but I have never worked on the starter.

First,what type of oil being used? If the oil contains "Friction Modifiers", the starting clutch may be slipping.

Best Oils To Use In Your Bike (Just My Opinion)

Engine oil : The commercial grade oils are clearly superior to the mass market oils. For the best protection in your bike or car, use Shell Rotella Synthetic, available at Wal-Mart in blue containers . For the best petroleum oil you can buy, get Shell Rotella T, Mobil Delvac 1300, or Chevron Delo 400, available at any auto parts store.

On the back of most oil cans is a circular stamp with the certification. Avoid oils that say "energy conserving" in the bottom half of the donut. These oils contain friction modifier additives that could cause clutch slipping over time. The EPA mandated certain gas mileage, so the auto makers turned to the oil manufacturers who came up with friction modifiers of the oil to meet these new standards.

All XXw-20 and XXw-30 oils are energy conserving, and should not be used in your motorcycle. Don't buy any oil additives like STP or Slick-50. Here's several listings on all about oil justifying these conclusions. "Oil is Oil" is not correct.

The Recommended Synthetic Oils :

Shell Rotella Synthetic
5w-40 Delvac 1 Synthetic
5w-40 Mobil-1 SUV/Truck Synthetic
5w-40 AMSOil AMF Synthetic (pricey, but it’s your money)
10w-40 Golden Spectro Synthetic
10w-50 Motul 5100 Synthetic
10w-40 Mobil-1 Synthetic
15w-50 Mobil-1 MX4T Synthetic

The best synthetics are: (in no particular order)

Shell Rotella-T Synthetic 5w-40 (blue container is synthetic, not white which is dino), gallon at Wal-Mart.
Mobil Delvac-1 5w-40 (grey container is synthetic, not black which is dino), gallon at Petro stations, gallon at Farm and Fleet.
Mobil-1 SUV 5w-40, qt anywhere.
AMSOil AMF 10w-40 synthetic motorcycle oil. (again, pricey)
Golden Spectro Supreme, (no price).
Motul 5100 Ester, (no price).

Mobil-1 automotive oils all contain small amounts of moly - about 100 to 200 ppm. This can cause clutch slippage in some motorcycles. I've only heard of this being a problem in Honda Shadows.


The Recommended Petroleum Oils

Chevron Delo 400 15w-40
Delvac 1300 15w-40
Shell Rotella 15w-40

The best petroleum oils are: (in no particular order)

Chevron Delo 400 15w-40 (blue container) gallon at any auto parts store, gallons at Costco.

Mobil Delvac 1300 15w-40 (black container) gallon at any auto parts store, gallons at Sam's Club.

Shell Rotella-T 15w-40 (white container) gallon at Wal-Mart or any auto parts store, gallons at Sam's Club.

Castrol 15w-40 (Green container) gallon at Wal-Mart or any auto parts store, gallons at Sam’s club.



Starter Solenoid/Motor Checkout Procedure

Some simple steps to determine what is working and what's not:

1.Fully charge and test the battery(most bike shops can load test the battery, and then use a floating ball hydrometer to check specific gravity in the charged cells).

2.Clean all battery terminals of corrosion.

3.Tighten all starting related connections(Positive RED(+) battery terminal, Negative BLACK(-)terminal) and from the terminal to the engine case. All connections must be clean and tight. If the cables feel “Crunchy” when flexed, they may have corrosion inside the insulation, requiring replacement.

4.Clean the cable from the starter solenoid to the starter motor.

5.Clean and check the "bullet connectors" going to the coil side of the starter solenoid.

6.Try again to start the bike, keep in mind some Kawasaki’s have a clutch interlock to prevent cranking the engine while it’s in gear, so the clutch lever must be squeezed.

7.If no luck, go to step #8

8.Wearing eye protection, bridge with pliers or a screwdriver the two heavy duty(large)terminals on the solenoid. If the bike cranks, your solenoid may be bad.

9. If the starter won’t turn over, one of several things has happened; The starter motor has seized due to brushes binding up, lack of lubrication in the bushings of the motor, the battery is weak , the engine has seized or it could be a combination of any of the above. A website for starter motors is:

A. http://www.psep.biz/store/mitsuba_starter_motors_page_2.htm

B. http://www.nationsautoelectric.com/Kawasaki.html

C. http://www.whitedogbikes.com/cat--Kawasaki-Starter-Motors-Relays-and-Solenoids--Kawasaki-Starter-Motors.html

D. http://www.ricksmotorsportelectrics.com/starters.php

E. http://www.dbelectrical.com/

10.The dealer may want $$$ for a new solenoid, but take your old one along and visit the nearest riding lawn mower shop. They have solenoids for about $15 that with a little work will fit. Be aware that the new solenoid from the lawn mower shop may require a ground wire for it to work.

11. I’d recommend upgrading from the existing battery cables to at least 6 gauge welding cables.
They are available in two colors(RED and BLACK) have more flexibility due to being constructed with finer conductors, and will fit in tighter areas.

12. The welding cable is sold by the foot, so take careful measurements or bring your old cables along. Most battery shops might be able to supply the cable too, so call to find out. The battery shop should be able to crimp/swage on the end of the welding cable the terminal ends or lugs using either a dedicated crimping machine or a tool that looks like a bolt cutter that has special dies to terminate the cable.

What does the bike exactly do or does not do, and what do you call the 'starter'. I assume it is a 750 four.

Power goes to the Relay, then to the Starter Motor. The Starter Motor spins the Starter Clutch and this the crankshaft,

If bike does nothing, 'nada' then it could be electrical; bad battery, loose cable, bad relay, or starter motor, and in this case, fixiing would be rather easy. If if sounds like marbles but does not crank, then it is the starter clutch and this is very involved to replace.

This went from a bad starting bike to " what oil thread " in one post ! :466

If you can bump start the bike and it runs fine then your battery isn't carrying the amps to give it the right kick it needs ( It can still read 13.8v but have no juice ). Try swapping it out with some one elses or try jumping it off your car battery - if these cure it then it's new battery time.

Then we will discuss oils :lkl
