1981 gs250t

[Guest]

Hello all here with a dream of swapping my 250 with a bigger motor.. anyone know whats the biggest motor size that will fit in a gs250t chassis and how much on average would that engine be

Although many GS450 parts fit the 250 I believe the 450 had 2 downtubes on the front of the frame instead of a single one in the middle. There might be a reason for that. That said, the lower ends look the same to me and it's probably just the brackets that are different for the different frames. I would go to a place like CMSNL and study the fiche for compatibility. Between the 250 and the 450 you also have the 400 and the odd 300 to play with.
