FZR250/400 engine

[garyhoons]

Hi guys,

A double posting ( repeated in the both the both 250 and 400 sections to get answers from both crowds in case the other doesn't know).

I have an FZR250 1989 model. A 2kr. The engine has just sh#t itself. Toying with the idea of doing a rebuild or replacing it with another to solve some of its other irritating issues.

Does anybody know if either an FZR400 engine of the same age, or a 3LN engine will fit into the 2Kr frame without having to do any major changes ? ? (supposed to be an 89, but i think an 88, there is no exup valve, not that I care if i get an engine that had one and Its just not fitted, I'm used to having no low end torque !)

Anyways, would appreciate anyones knowledge.

Thanks heaps

The 250 frame is too narrow for the 400 engine.

Yeah, i've been given that impression. Was just wondering since they are so rediculously similiar.
