Hi folks ,read this in a German site , seems a bit brutal , your thoughts on this please.
NOW REMOVE THE INLET MANIFOLD RUBBER FROM THE CRANKCASES, BY REMOVING THE 4, 10MM BOLTS ,REMOVE THE SMALL BLACK RUBBER 2 STROKE OIL FEED PIPE FROM THE RIGHT HAND SIDE OF THE MANIFOLD AND BLACK IT WITH A MATCH STICK OR SMALL SCREW. THEN CAREFULLY PRISE IT FROM THE CRANKCASES.
WHEN YOU HAVE THE MANIFOLD FREE YOU WILL SEE A SQUARE RUBBER NOSE PROTRUDING FROM THE BOTTOM OF IT. THIS NEEDS REMOVING , CUT IT OFF WITH A STANLEY KNIFE OR SIMILAR BE CAREFULL AND WATCH YOUR FINGERS ONCE THE NOSE IS REMOVED THE HOLE NEEDS CHAMPFERING OUT FROM THE CENTRE OF THE HOLE TO THE EDGE OF THE MANIFOLD TO CREATE A SMOOTH FREE FLOWING FUEL FLOW. IF YOU DONT FEEL LIKE TACKELING THIS SEND IT TO ME WITH £6 AND I WILL REPLACE YOUR ORIGINAL WITH A MODIFIED ONE.
Even race bikes have these 'fins' installed on them. I rememeber on my old 2001 DTR someone had done this 'Mod'. The guy I sold it too went ballistic! (He was a mechanic) Saying how unnecessary it was.
I believe even the YZ has these 'fins' and why would they restrict a race bike?
