trials lad Posted February 15, 2004 Report Share Posted February 15, 2004 Hi all When my '99 montesa is hot, at about a quarter on turn on the twist grip the engine starts running like its 'missing a beat'. As I said it only does this at a quarter turn on the twist grip any higher or lower it runs fine. What is wrong with it? Thanks in advance danny Quote Link to comment Share on other sites More sharing options...
