You need to have the valves adjusted. If they are not done soon you will have to replace more parts. Also do a oil change and filter change.

    You can't adjust the valve lash in a kawasaki 1500....because they use a automatic hydraulic valve lash adjusters on the end of the valve rocker. Its self adjusts with the oil pressure increase from higher rpms. As soon as you apply the throttle you should not hear the tapping because the lash adjuster needs pressure to work properly. The only fix is to pull the motor and replace the adjuster like I did. My custom 1996 kawasaki vulcan 1500 classic (big red) graced the cover of motor cyclist in 1998 so I know what I am talking about.

OK my 95 Chevy 1500 2wd 4.3 manual transmission, seems to have a little loss of power it smokes a little out the tail pipe and every time I give it a lot of gas the oil pressure goes down will bottom out...


Yes, it could be connected. If you run an engine with straight pipes, there will be no back pressure from the exhaust system, and the gas flows very fast out of the engine past the exhaust valves. This will cause the valves to heat up more than the manufacturer's spec and could burn the valves.
This in turn will cause loss of power. Overheated valves will cause the valve stem seals to harden and even to disintegrate, causing slight smoking from the tailpipe.
The oil pressure is a sticky toffee. If you have enough oil in the engine, you should have equal pressure at either low or high speed, unless you have a dicey oil pump, or oil level is low, causing the pump to lower the level in the sump or cavitating (sucking in air with the oil).

2007 Kawasaki Vulcan 900 Classic LT misfires at low RPM


Hi, Anonymous and the usual suspects are:
1. Severely discharged or a damaged battery should have 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a cursory reading of 12.5 volts or more but little or zero amperage the battery is faulty and must be replaced, AGM batteries fail in this scenario more so than lead-acid batteries.
2. 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.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking check for spark leakage in the dark
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Dirty air filter.
10. Intake air leak.
11. Water, dirt, or rust in the fuel system.
12. Carburetor contaminated, sticky float, plugged jets.
13. Carburetor has oil in the bowl due to excessive oil in pre-mix.
14. Carburetor vacuum diaphragm torn, cracked, not seated or installed improperly.
15. Multiple carburetors out of sync.
16. Fuel filter clogged.
17. Old or contaminated fuel.
18. Fuel tank vent system plugged or carb vent line closed off.
19. Gas cap diaphragm valve faulty.
20. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
21. Carburetor controls misadjusted.
22. Incorrect valve timing.
23. Valve springs floating, weak, or broken.

I changed the engine oil, filter and spark plugs in my 1999 Volvo 940 (1996 cc). Upon starting up, the engine runs at lower rpm and "hiccups" at idling.


Engine stalls or RPM fluctuates at idle up and down.

This problem is commonly caused by a dirty automatic idle speed control valve and throttle valve but always run a OBD2 fault code as well as the cleaning procedure. Buy a can of throttle valve cleaner (do not use carburetor spray cleaner!) from NAPA or Carquest (made by CRC chemicals) and spray it into the air intake while the engine is running, use up about 1/2 the can, engine will try to stall hold the speed up, shut it down and let it soak for 30 minutes, restart and blow out the remaining fluid, shut it down and disconnect the negative battery cable for 5 Min's to reset the base idle control

Backfiring and missing Sitting 1 month idle, ran good for about 10 to 15 min-smooth and full power. then started running on one cylinder?


It sounds like you have a stuck valve. Without major work, try to get it running and spray come carb cleaner in it.

Engine tapping


Low oil pressure at low rpm's Not enough pressure will cause hydrolic lifter or tensioners to get "lazy" incorrect oil type, synthetic oil and pump gear tollerances will cause these symtoms
