changed the plugs and fitted the power commander yesterday all went ok apart from a rounded velocity stack screw which had to be drilled out with a extractor which was the best £10 ive spent. The plugs where black and air filters dirty so replaced both and be looking for a k&n to sit with the pc3, i was shocked how the condition is around the rad etc now this bike has had one owner 25.000 miles when i brought it and with it having heated grips on it says it was an all year commuter, after my experience with this im gonna replace the rad clips and hoses and keep on top of it all, Thanks to all advice glad to put an ending to this post
I may have a brand new set of Samco hoses in red for the RR4-5 up for sale soon if you're interested mate?
