I am just about to purchase a new 700xx and i just wanted to go over a few things about honda and their valves.
I currently own a 04-crf450r dirtbike and am hesitant to go with honda again because of all the valve problems they had with the 450's. anyone who has owned one knows what i am talking about. the valves need to be reshimmed every 10-20 hours due to the titanium intake valves stretching and creating zero tolerance on the valve lash. I understand that the 700 is not a racing engine so the cam and valves are prob different than the 450. I have heard of some catistrophic engine failure on a few of the 700s involving the valves but the cause seemed to be less experinced riders over reving the engine.
I would like to get a first hand view of people that own the 700 to see if anyone has noticed any problems.
Have the clearences changes at all since time of puchase??
thanks
