Only refer to this customer complaint after a complete check using the XR25.NOTES
Check the air filter is not deformed.
Check the fuel
Check there is fuel present
(fuel gauge faulty).
Check the fuel is of the correct type.
Check the hosesCheck no hoses are pinched
(especially after a removal operation).
Check the air filter
Check the oil levelUse the dipstick to check if the
oil level is too high.
Check the condition of the manifold gaskets.Check the inlet
manifold
Check the exhaust manifold is not leaking.Check the exhaust
manifold
Check, after removal, that the injectors do not drip.Check the injectors
Check the throttle body is not contaminated.Check the throttle body
Check the brake servo is not leaking (noise).Check the brake servo

CONT
Only refer to this customer complaint after a complete check using the XR25.NOTES
Check the calipers, drums and bearings are not seized.
Check that the tyres are not under-inflated.
Check the coolingCheck that cooling is not insufficient.
Check the canister bleed
Disconnect the pipe connecting the canister bleed solenoid valve
to the inlet manifold.
Plug the pipe to prevent an air leak.
If there is no other effect, the canister bleed is faulty.
Check the axle assemblies
