SOURCE: i have a 06 rmz 450 and it is geting hard to kick

I have a customer expieriancing the same pronblem I would lean to the cam timing or the auto decopresion is worn out from what I can see the part is real loos in the cam and may not be holding as it is passing the shim cup. But first thing check the cam timing as the chain can become very loos due to the manuel screw that gets ignored and the cahin will come loos.

My 2004 rmz 250 4 stroke lost power died went to kick it over and it locked up what causes that?


Hi, William you may have hydraulic lock caused by excessive liquid in the cylinder or you have squeaked your top end this is commonly known as "HEAT SEIZE" the piston heats up expands and becomes extremely tight in the cylinder bore and usually occurs mainly on 2 cycle engines right after a fresh top end rebuild, but it can also happen to brand new motorcycles, these are rare instances due to better quality control and education. Overheating failures that cause pistons to seize are many and each one should be carefully diagnosed to prevent future repeat offenders and the usual suspects are:
1. Lack of lubrication due to low or no oil.
2. Among the causes of lack of cylinder, lubrication is clogging of lubricator by dirt or waste, obstruction in oil pipes/lines, leaky check valves, leaky pump packing, broken oil pipe/line, oil too cold to feed.
3. Wrong type of oil used in premix or oil tank.
4. Improper premix ratio you should start with 32:1 as a baseline.
5. New rebuild piston to cylinder tolerances set up too tight.
6. Failure to follow proper break in procedures with a 16:1 premix ratio.
7. Loose fasteners causing intake, base, or head gaskets to leak or blown crankshaft seal, failure caused by age, overheating or walking. 8. Holes in the intake manifold bent or warped intake flange or reed cage any stray air coming into a cylinder will cause a super lean condition.
9. Improper assembly of reed valve gaskets.
10. Insufficient warm up time for temperature conditions before WOT.
11. Broken, pinched or cracked fuel line.
12. Carburetor fuel passages clogged or restricted from stale fuel varnish, ethanol sludge, dirt, rust, or fuel level in float bowl too low.
13. Main jet size too small or partially clogged
14. Air filter improperly installed, missing or not sealing.
15. Faulty or improperly adjusted oil pump and or cable.
16. Failure to bleed oil pump after a rebuild/replacement or running oil tank dry.
17. Engine coolant level too low, too old, or improper mixture ratio.
18. Radiator clogged, fins damaged, or faulty cap.
19. No liquid circulation due to failed oil or water pump.
20. Cavitation due to air in oil or coolant system.
21. Water and oil mix due to blown head gasket.
22. Timing retarded due to faulty CKP sensor or CDI.
23. Improper spark plug heat range (too hot) and or gap.
24. Excessive engine load, brakes dragging, clutch slipping, transmission lubricant level too low or viscosity to high.

My 2010 rmz 450 crackles and pops at low revs, and surging when cruising, also backfires when i shut of the throttle, i have fitted a wiseco fuel mangement unit and played around with it but no luck,


sounds like a few things, bad/fouled spark plug,old/clogged fuel filter/old air filter or bad fuel. When taking bikes out of storage bikes often suffer from this problem from old fuel sitting in bike gumming it up.

How do you drain the fuel out of a 2008 suzuki rmz 450 motocross bike thats fuel injected?


Remove the feed pipe to the injectors and you will be able to drain the fuel, but you will have to use the ignition to do so.
The other way would be to remove the feed pipe to the pump from the tank, this way you will be able to remove the fuel without the ignition.
Hope this helps!
