Q: What kind of power increase can you expect from this big bore kit on a WR250F?
3 months 3 days ago
Just trying to debate if it's more cost effective to install/tune the WR250F with this 290cc big bore kit, or just sell and upgrade to a WR450F or similar. (for the record, I'm not "unhappy" with the WR250)

A: You will gain a noticeable few horsepower with the big bore 290 kit. It won't be 450 power but at the same time the 250 is going to be lighter and better handling than the 450. It will really come down to your riding style and personal preference.
Q: Fits the original cylinderhead with this kit?
