I've just brought an 07 at an Auction and when at a constant speed the engine seems to pause for a second. What I know about the bike: It has been sitting for a while before I got it Done 800km from new Replaced the fuel The shop who sold the bike rejetted it, took out the air box and disconected the grey wire. I know that the WR do have a pause in the cycle but it feels more than it should. When it pauses my body moves forward. Does this sound normal?
