Niro12 Posted 6 hours ago Report Share Posted 6 hours ago What is my best option for alternative cylinder (barrel) for 1975 TY175 USA? DT175 or CT175? Or maybe something else? Thanks Quote Link to comment Share on other sites More sharing options...
feetupfun Posted 2 hours ago Report Share Posted 2 hours ago DT175 1974,75,76,77 (DT175 ABCD models) cylinder will fit and function well but has different finning outline to TY175. I have not tried or measured up a CT1,2,3 cylinder. Quote Link to comment Share on other sites More sharing options...

I have not tried or measured up a CT1,2,3 cylinder. Got it. In case I'm going to use DT175 cylinder - - Do I need to use DT175 cylinder head? - is it possible to make a new thread for the clutch cable holder? - Do I need to trim the fins? thanks.

You can use the TY175 head or the DT175 head. If you use a DT175 head, the compression ratio will be higher but you may need to trim the head fins for exhaust pipe clearance. You can mount a clutch cable holder on the engine casing or on the bottom cylinder fin. The DT175 cylinder fins will not interfere with anything physically. Trim them if retaining the original TY appearance is important to you. Quote Link to comment Share on other sites More sharing options...
