I checked out a 1995 kdx for my son to learn on. It seemed to be in decent shape except for a noise in the engine- it is a light rattle from idle to high rpm. The owner said that it has always been there and never get worse. He said the top end has been replaced and gone through professionally. Is this noise typical of this model. Thanks
It is usually the power valves and/or clutch and/or the power valve actuating linkage in the bottom end. Either way, it is normal. Add a full litre of oil to the tranny to quiet it down some.
thats awesome my bike makes the same sound and its good to know that its just normal...its been there for some time now and it never got worse or quieter so i wasnt worried bout it but at least now i know
The sound I am hearing sounds like a valve rapping, or knocking sound in an old chevy 6 banger when running low octane fuel... It's fairly loud and only when I am grunting through a higher gear than necessary, for example at lower RPM's in 5th and 6th gear... It does seem to go away when I get her screaming at higher RPM's but have been cautious... Is this really normal??? Mine is a 1994 KDX 200
