I think someone went way to far on this one but I don't ever play with the 250's so..... What do you guys think?

The four stroke engine: That's one stroke for producing power and three for wearing the engine out.

I think in Hot Rodding terms, that is called "Hogging it Out".  :-D It's a little hard to tell without having it in my hand, but it looks like they went too far.

Hard to say by the pictures if it is to far, I can say it looks kinda ugly and was done in somebodies garage that maybe didn't have the right tools. the flywheel may have been added by someone other than the original owner to mellow it out. the 98 250 was an animal, kawie detuned them in 99, but installing a wiesco flat top and have the head contoured made them pretty potent.
