I think it will. If you look at biebandit.com and find the oem Yamaha parts for the motorcycles in question and check to see if they are the same part number, if they are then they will interchange. you can crosscheck different years too if you found a 1975 ty 175 cylinder for your 1975 dt 175. So check out bikebandit and see for yourself, they are the next best thing to a Yamaha dealer.
Yes, the Yamaha Tri-Moto 175 requires a gas-oil mixture for proper operation, as it has a two-stroke engine. Typically, a mixture of 32:1 or 50:1 gas-to-oil ratio is recommended, depending on the specific model and condition. Always refer to the owner's manual for the exact specifications to ensure optimal performance and longevity of the engine.
