Hi All,
I what to know the sizes of the holes in the jets in mm i.e 110 = what, so I can re drill the jets i have until i hit the right number.
I have built a new exhaust system to quieten the 550/4 chop down, 2 into 1 into a common silencer box under the frame but know it runs rough. (needs more fuel).
With 4 straight throughs, it went like a scolded cat, but it was way to load.
With the new system it is whisper quiet (and before anyone says its to restricted the silencer is of a re direction type. Newton third law and all that).
Thanks
Paull
