fantic303 Posted December 1, 2007 Report Share Posted December 1, 2007 Does someone with a 2007 4RT can tell me what the service manual from the 2007 says about the valve timing, and what these values are ? They say that the 2007 Mont has another camshaft, but in the 2007 partslisting the part number is the same as in the partslist from a 2005 montesa.

nigel dabster Posted December 1, 2007 Report Share Posted December 1, 2007 my understanding is the cam was changed on the 07. It may be that the part nos are the same but the part is actually now the new type? Quote Link to comment Share on other sites More sharing options...
