a while back when I picked up my new bike i started a thread about the bike ergos....yada yada.
Well I got her set up the way I like, and this thing is great. best handling bike I have ever ridden, It turns quick and precise, Its smooth in the rough slow stuff, and takes big hits really well.
the stock engine is the best off road power plant I have had the pleasure to ride.
IMS 3.2 gallon tank
race tech springs .46 front, 5.2 rear
fmf turbine core spark arrestor.
I really don't think the bike needs any engine mods for my riding style, It chugs down low if I make a mistake, and the mid and top are strong enough for my advanced age.
So I feel kinda silly for complaining about the set up earlier, It just took me a while to sort it out. I highly recommend the new yz250 for hare and hound racing.
