    you will need a socket set rangeing from 8 to 19 ml also ring spanners of the same sizes a torque wrench screw drivers philips head & flat head and most important a valve spring compression tool also valve lapping paste & sticks assumeing you have all these tools remove the tank seat & side covers this will give you acces to the engine disconect the top radiator hose after you havedrained at least half of the coolant remove all the plug leads remove all the bolts from the rocker cover & carefully remove the rocker cover at this point rotate the engine to bring the cam sprockets around to where you can see the the inlet & exhaust marks with nos 1&4 pistons at top dead centre I suggest at this point you place some rag under the cams to prevent anything from falling into the camchain galery or the bottom end. now carefully remove the cam chain tensioner located at the rear of the engine on the left hand side now undo the camshaft journal caps turn each bolt a little at a time to prevent the camshaft from lifting at one end ahead of the other once you have removed the journal caps mark each one as these parts are line bored puting them back in the wrong place will cause irreparable damage now that you have removed the bearing caps carefully lift the cam & draw it out from under the cam chain after haveing succesfully done this remove the head head studs also useing the same method as with the cam journal caps a couple of turns at a time on each stud until there is no tension remaining once all the nuts have been removed from the studs lift of the head place the head in a suitable wash tub clean away all oil & carbon deposits dry with compressed air or the misses hair dryer if you dont have air. Take the valve spring compressor & place the fixed end on the valve face turn the screw piece down on the valve spring collar until the retaining collets cabe seen to be lose a magnet or tweesers are the easiest way to remove these remove the collets & losen of the valve spring compressor take it of & lift the valve spring out push the valve stem through the guide there you go first valve now cary on with the same procedure for the rest of them heres where you will need the shop manual for specs valve angle valve spring lengthvalve stem clearance in guides etcshoud the valve seats need to be recut this job is best left to some one with extensive expierence in this area & ifyour going to get someone to grind the valves & cut the seats you would be well advised to get them to rebuild the head however should you decide to go it alone use the manual to help you through each step reasembly is the reverse of ALL the procedures to dismantle you will also need to check the manual for the number of links in the timeing chain between the timeing marks all the best ask if you need help along the way its not an easy job for a novice but it will be rewarding if you take your time & be carefull check & recheck each step

Why wont my 09 ninja 650 run

Hi, Keith and the usual suspects are:
1. Fuel tank empty.
2. Fuel supply valve/petcock turned off.
3. Fouled spark plugs.
4. Engine flooded as a result of overuse of the enricher.
5. Vacuum hose to the fuel supply valve/petcock disconnected, broken, cracked, or pinched.
6. Fuel valve/petcock or filter clogged.
7. Fuel line to the carburetor or throttle body pinched or kinked.
8. Carburetor float stuck.
9. Fuel injectors clogged.
10. Severely discharged or damaged battery you need 12.5 volts or better and be able to pass a load test if necessary.
11. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
12. Loose or corroded wire connection at the coil, battery or plug between ignition sensor and CDI box.
Spark plug cables in bad condition and shorting check for leakage in the dark, cable connections loose, or connected to the wrong cylinders.
13. Ignition timing incorrect due to a faulty MAP, CKP, O2, TPS, sensors.
14. Faulty neutral, clutch lever, or kickstand safety switch.
15. Faulty fuel pump or fuse or relay.
16. Faulty CDI box.
17. A stuck bent or burnt valve.

How can i tell when my 2002 kawasaki ninja 500R needs a tune up?

Check the maintenance schedule in your owners manual or on The 500 requires a valve adjustment and carb sync every 8000miles. Spark plugs should be checked and replaced, if fouled at the same time as the valve adjustment.

Valves tapping

you can put some thicker oil in it, or some oil additive,, however this is not recomended, the valves need to be adjusted. They are shims adjustment, and best done by a mechanic.
