[QUOTE="Eric Gorr, post: 975798, member: 17225"] Hi Skip, The 2002-04 top ends interchange but the 03 is the best design stock. Its best to just port the stock cylinder because the cylinder is very thin and boring it oversize makes it less reliable but its a cheap fix if the bore ever gets trashed from a broken ring. The difference in the KTM is its 15 years newer than the Honda. The exhaust valve system with the triple exhaust combined with low and wide transfer ports is the key. Remember the 2002-04 CR250 engine is actually an older generation than the previous 1992-2001 engine. The 2002 CR250 originated as a dual sport bike in Japan in 1988. If you like the KTM then buy a KTM because no amount of money is going to make the 2003 CR250 the same as the KTM. Good luck, Eric [/QUOTE]
