My '98 WR400 has a problem: when warmed up and in first or second gear (at least thats when I notice it) when I close the throttle from about 1/4 - 1/3 turn, revs come down but then hang at a very high idle and dont come down until I very slightly blip the throttle, then it settles to normal idle. This is the only way I have so far found to get rid of it. Doesnt do it all the time, but most of the time. Anybody any ideas what might be going on ? My thoughts so far... - I cleaned and lubed the throttle cables very recently so I dont think it is that but if anybody thinks different let me know - I did find it a PITA to adjust the cables so the throttle rolls/snaps back easily, which it still does by the way. - A high hanging idle is a sign of lean on the pilots (I think) but my understanding was that revs eventually drop on their own if this is the case. Carb slide problem ? Jetting is not what it says in my signature, its now stock (EURO) with JD blue needle and a slightly smaller start jet but still de-octopussed!
