Hello, I just got a yamaha 225 trik (shaft driven) and was wondering what the diff was between a 225DX, and a 225DR? is it in the motor, or the shaft? Cuz I torn apart the trik the other day and found the U- joint had snaped. I went in to the local dealer for the parts, but they wanted to know if it were a DX or a DR! I guess they want $425 +tax Canadian for the U-joint and yoaks. I'd never pay that much for it (the trik only cost $250). So I'm currently locating a u-Joint off the steering colum off some old swather or somethin...... and modify it to fit! does anyone know what machine (combine, swather.....) would be the closest Fit?
