Ys 120 muffler thread
 

Hello,
Just bought a YS 120 with no muffler.Any idea what size is the thread for the muffler ?
I am looking for a muffler and pipe.
Thanks
Phil

Thanks to Dave: Although RC Specialties does not recommend their Turbohreader for YS, they do have right angle adapters that will fit YS. Here is a copy of their website info.: Looks like it 13mm x 1mm thread for the 120.

Here is a link to a chart with many 4C engine muffler and crankshaft thread sizes. This will give you some options. For a short time I used the muffler off my YS 63 on my Enya 90 4C.
