Notes:

• ‘c’ is the distance of mounting bolt (centre to centre) (note; 35mm silencers will also fit O.S. and O.S. ‘copy’ engines that measure 35.5mm)
• Bolt: If the silencer ‘bolt’ size is Mx eg M3 – it means M3 bolts thread into the silencer flange, if ‘bolt’ size is xmm eg 4mm – it means that there is a hole for a 4mm bolt to go through the silencer flange and (thread) into the engine crankcase
• ‘e’; total length to end of bolt (inc. locking nut)
• Weight is in grams (1oz. = 28.35g)
• Measurements are in mm
