Hey guys,
I'm going to have a look at an 06 WR450F (to replace my old YZ250). I'm buying it privately and wanted to do a compression test on it to ensure the the engine is OK. Does anyone know what the compression should be on the 06 Models (is it also the same on the 04/05 models)? Also is it as simple as putting the compression tester in and using the electric start to check, or is there a decompression switch I need to turn off to get an accurate reading?
Also if you can suggest any other specific things to check for that would help a lot!
Cheers!
Craig.
