Question, how much diff was the 295 kit compared to the 250cc deal in terms of power?? which kit is it??
i have the eric gorr yz295 kit. i went with his "overall" or "mo betta" power spread. it has a lot more power right off idle. With the overall power spread it comes on the pipe smoother but still hits like a ton of bricks. the pistons weight the same as the oem so it it still revs like a stock bike just with more grunt. similar 4-stroke like grunt off idle to a ktm 300 but a lot more exciting up top. perfect do it all bike for me. mx, single track, gncc, you name it. i put over 100 hours on my kit already and i'm on my second topend.
my buddy went with the mid/top porting which has a bit more up top and nice over rev. if you ride purely mx this is the kit for you.
not any huge jetting changes required but even though i had the head cut for pump gas.....i was getting some detonation and had to switch to 100ll fuel. otherwise just bolt it on and go.
