YZ250 345 big bore kit

Recommended Posts

Just been looking at a 345 big bore kit for my YZ250 2 stroke , Does anyone have any experience with them

that just sounds straight insane. No one needs all that power! Lol. But seems like a lot if extra stress on a motor that's built for a 100cc less. Could be wrong but I'm a bit skeptical.

I took mine out today with my apt smart carb:) and she is running almost flawless just a little miss on the very top ill call apt monday and get a metering rod on its way. I cant believe how hard it pulls i did the wr 3-5 swap and im loving the extra top speed. I still have some playing Around to do before i call it good but its getting there.
