i had a very nasty flat spot at peak power around about 7.5k on an st2 some times it was that bad i could hardly ride through it tryed every damn thing you can think of even got nelly to have a look he couldn't find any thing wrong either in the end he suggested an injection cleaner and poured me a good shot in to the tank bloody hell did she enjoy that went like bugger all i can say is my injectors must have been well blocked |
