I just remembered the biggest stroker ive seen for a ex is a 500 but I forgot who sells it.For just bore I am pretty sure 440 is the biggest.You can get them alot of different places.

When you put big bore kits in 4 strokes does the engine become really fussy?
The only experience i have with big bores is on snowmobiles and those are two strokes.
thanks
