"KX144" big bore KX125 woods bike? Eric Gorr low/mid porting & 93 octane head woods rideability?

[Chuck78]

Although I've learned of shops that do 125 big bore stroker engines to the tune of 151cc and 167cc KX125's (with a 100 octane fuel requirement... and a hefty price tag at least for the complete engine build from the shop named MaxRpm), I've decided from riding a few 125's and many KDX200's & 2 KTM 200's, that I just really REALLY love a modded 220 engine above all of them... So I'm looking at a 99-02 hybrid build potentially, but definitely decking out 1 of my two 220's with an expensive dose of titanium parts all over, including the heaviest fasteners (axles, swingarm pivot, rear suspension linkage bolts) and a lot of smaller fasteners in order to really see how much lighter I can make it feel at least to pick up when dropped, or for very low speed gnarly terrain navigating...

Weigh that seat before buying Ti bolts. :-)

You know I went down to the basement yesterday morning and grabbed my spare KDX seat, and it didn't really feel all that heavy to me whatsoever. Next time we have the seat off of my wife's KTM 200 that has shaved thinner foam, I'll compare the two, that's as close as I can get to a KX 125 comparison.

I'm sure the KX seat is lighter, but it didn't seem like there was all that much weight savings to be had there especially with the trade off for comfort.

That in combination with the aluminum seat subframe might make enough of a difference, as well as the fuel tanks being smaller on the KX models. Maybe the perimeter frame design slopes down a little further or is made out of lighter weight chromoly tubing on a KX? Hard to say.

I do have a spare 220 engine though, & an assortment of KDX H series pipes...
