My 1975 DT400 lives again!

This piston was perfect, exactly what I needed, it was tough to find one and vintco came thru and helped me out! Shipping took forever (I am in Ontario Canada) but the piston quality was excellent! Only thing that would be nice is if they included a wrist pin bearing along with the kit, considering it’s not exactly cheap!
<br>5/5 stars, great product and great company!
