Goofy Footer 539 Posted January 23, 2023 @Mr.JAJA I thought you'd enjoy this build, take a look @tntmo and @kato you've both built motors, what do you guys think of this! 1 Share this post Link to post Share on other sites
kato 53 Posted January 23, 2023 I saw that a little while back and as a yz250 owner I feel This much money would be best invested elsewhere (wide ration transmission for instance, if like me you ride trails or desert). But maybe I’m the wrong guy to chim in since it doesn’t take much to make me happy. Love this thing! 1 Share this post Link to post Share on other sites
tntmo 887 Posted January 23, 2023 I sent this to you a long time ago! Pretty cool but it’s more money than I want to spend on something that is too powerful for me anyway. I’m better suited for a 125! Share this post Link to post Share on other sites

robertaccio 406 Posted January 23, 2023 (edited) YZ250 the do all machine 99% of riders need nothing more to kick their arse in the name of power. I've recently built up 2 offroad steel framers (early 2000s models). 18in rear wheel, FMF Gnarly with appropriate silencer (TC-2 or PC), Steahly FWW mid weight, stock gearing remains add some handguards , proper carb spec, V Force 3 reeds (or 4 if its a new one). Suspension for off road and good to go. Just such a great package. The new YZ250X is an absolute beauty that for 99% needs zero!!!! maybe just some springs for weight of rider match..

I have safe and bullet proof set up tips. Also suspension? wheels, mousses? Carb jet block oring/sealring replaced?
