Has anyone tryed to put a yamaha 250 4 stroke on a shifter kart ? is this the way of the future or will the karts just not perform with the 4 stroke I would like to see it happen just so I don’t have to keep spending money on this swedetech motor If we could get a class for the 4 stoke shifter class I would go buy a 4 stroke motor for next year for sure anyone know where this subject is going??
kart sport mag. tried that they said the icc would pull away on straits but it would catch up in the turns and a lot less mantence
Keep in mind that the YZ250F costs $3900, plus you have to find someone who will make a mount and pipe for you, plus find/make a 428 drive sprocket (or find 520 rear sprockets) since bike and shifter karts use a different chain size, plus find/fab a J-Arm, plus ???$$$. And who’s going to help you to tune/troubleshoot it?
Not to mention there’s no plan to include them in the shifter classes, as far as SKUSA is concerned.
There is a complete spec 4 stroke 225cc Yamaha air cooled kart called the Exciter, but not too many places run it, and the ones that do are in the Midwest.
If you want low maintenence, try stock moto (if you’re a senior). Half the cost of the 250F, and lots of special parts and help available.
Or if you really like 4 strokes, see Brad about a Biland (it’s not a shifter, though).
Don’t get me wrong, I like the idea too, but until cheaper moto two strokes disappear there won’t be much interest from the sanctioning bodies.
Maybe you guys should talk to Brad about the new Italian Orele (spelling?).
250-4 stroke which can get you either 30 hp or 45 hp depending on the carb used! Large power band with 13k rpms. Either run as a shifter or Tag kart.
that sounds good
:jumpmay be the SKUSA will start something in the next few years but if so I want to sell my 2 stroke wile people are still using them like right know now one will buy a 2 stroke dirt bike its stupid! and I want the low mantanece factor also So I can lern to drive better!!
does the 250 yamaha have 4 gears or 5 ? I now the 450 yamaha is only 4gears
