Nso20 Posted August 21, 2015 Share Posted August 21, 2015 Hi allHave just joined so howdy! Have an 1990 registered 350 F2 which is lovely and clean, runs well and has just over 19000 miles on. When under load, it has a slight hesitation from about 5000 to 6000 revs. When it clears 6000 it really flies! Just wondering if anyone has any ideas please? Cheers guys.
