Its actually pretty easy...You remove the carb and then the four (4) bolts that hold on the reed cage. Remove the reed cage assembly,then post a picture,so we can tell you what you have.
not overly bent mabey 1mm over flush with the cage but thats it in my opinion any higher and I wouldent be comfortable running them they seam stock but where is the metal back flaps (forgot what their called) reed stops
