I have a 1987 DT115, ran great last year, was winterized and carbs drained, starts good and runs up to 5000 rpms but anything over it starts to miss attempts to clean up will start to run right but falls back to missing, it feels ignition, coils, cdi pack, pick ups? changed plugs just see see if something changed it didn't, runs fine below the 5000 mark, over rev limiter doesn't come on nor does any other alarm, hit choke when it started to see if perhaps fuel delivery wasn't it. Runs so good below the 5000 mark
