thanks for all the advice once again.
was out on the 748 again today and the benefits of the strip and clean have already worn off - i was half way past a car when it started to slip - so i was riding alongside them, more or less at the same pace with the engine wailing away, all about 2 feet from their side window! i felt quite sorry for the driver as they must have wondered why this black clad, black visored nutcase on a black motorcycle with open pipes was riding in formation with them absolutely revving the nuts off his bike!
anyway - ST4s clutch and spring kit on order from nelly.
thanks again for all your help.
