Greetings from Tennessee 

 from near Salisbury, UK.

1971 CT1C amongst the pack in my (too small!) garage.

Make sure that you replace both sets of brake shoes. CMSNL and Partzilla should have the current Yamaha part numbers, and you should be able to order them through your local dealer.

Have a look at my post immediately above yours. 

J'avais trop envie de la montrer, mais ça ne passe pas !

Voilà une première info de taille : CT1C correspond à quelle machine ? Je découvre !

Moi c'est une DT 400 B de 1975 (501) : ça correspond à quelle désignation ? 

Hello all , love all motorcycles but the old ones like kz’s,cb’s really my favorite. Had a R5 several years ago and loved it. Getting mid 60s and thinking how easy 2 strokes are to work on and most not too heavy so here I go . Grabbed a 75 DT175 and a 73 CT1 175 which seems have been vintage racer at one time. Has the compression release still there but has double plugs ) , hooker exhaust ? , spokes are tied together on both wheels , headlight with on and off on bucket , no taillight or signals. Both fender changed to chrome 
So now got few 2 strokes , 73 ct175 , 75 dt175 , 85 ty350 plus some dirt bike stuff. I’m by Fort Worth Texas so if you got any of these old 2 stroke bikes give me a holler always looking .
I also sell parts mainly leftover NOS shop buyouts and 72-80 z1/kz900/1000 . 
Thank you for letting me join and look forward to learning about these old Yamaha motorcycles. Hello all , love all motorcycles but the old ones like kz’s,cb’s really my favorite.
