Awesome!! Ive heard the kx's need more low end, did the build deliver? Did you happen to measure the squish after to see what it was set too? Thanks for the cool content btw!!

Good build. Tem dirty bolts on the clutch cover though....everything else looks so spotless it makes them stand out. sweet clips, that kx is sick!

I have a 03 kx250 and 03 kx500. How much of a difference is the 250 after the port and polishing job?

Hi m8 nice build . Did you have too replace you power valve sub piston levers at all ?? Mine are stuffed ,07 kx250 .. having major trouble find new ones , 13236-0054

Bad ass

That bikes gonna rip man 🔥🔥

You could blend 100LL AV Gas. Just google octane calculator to figure out how much of each to get you desired octane

U should do a smart carburetor with tps for this build

This looks like a 2005 engine? But the frame? Perhaps is painted. As i got a hold of one myself a 2007 kx 250 last year of production i am going to tear it apart, as i am going to cryoheat the transmission gears. But in all honestly i am semi novice so i am slightly worried wich parts that might be in the spectrum of being weared and how to properly analyse them. Doing a long term project of a factory replica with carmichael rc 2001 and stewarts sr 05. So obviously the engine is going to be sent out for vapor blasting, coatings etc, but i want to do the tear down of the engine /parts myself. It will be a tricky build but i guess i also learn along the way. Just happy that i found one in mint condition with only one owner.

Try the b9es or b9eg Both race plug $5 to $7

I've never considered NGK as cheap plugs. All my engines have them.
