Hi I think /thought I bought a wide kneck TV2 airbox but it has a the spring clip for the elbow? my early S2 Li125 airbox has the narrow neck and thumb/buterfly nut, so did the TV2 wide neck change to spring clip type towards the end of production, or have I bought a lemon, either way it will work for what I need, but curious.
Part no I have is IGM-2105 S ?
Thanks Paul

As far as i know the airbox was changed on all series 2 models to clip type when they changed the carbs fro Bs5 to Bs7 ,

I've got a 'wide neck' airbox in front of me and the neck measurement is as follows: OD 42mm, ID 39mm (at the skinniest part). It has no IGM.

To the best of my knowledge the TV/2 had the skinny neck airbox (with the S3 style internal baffle) from very early 1960 until end of production----the change corresponded with the change from the MA-23 to the MA-21 carb. Happy to be corrected but didn't the the late airboxes retain the skinny neck despite the change from MA-21-BS5 to MA-21-BS7 and the change from the wing nut to spring clip?

Hmmm the plot thickens ! I will measure mine tomorow and see too ?
Thanks Paul

Airbox filter pipe was screw on until Jan 61 and clip on Feb 61 until end of production.
My early ridgeback 1959 version has the airbox with large hole and no swan neck in it, my later 1960 TV has thin neck airbox with swan neck fitted and both are bolt on type.
