Yamaha

so i jus got this bike a few months ago.
its been actin up alot.
it wont start now.
ive ridden it a few times
and when it first stopped working
so my dad took it over next door
and the guy told us is was our spark plug
so i cleaned it and sanded it and everything
and then it was working fine.
then yesterday i went to go ride
it and it didnt work
SO
i took out the spark and it was fouled ..soo quickly...
so i cleaned it sanded it checked to see if it sparked
which it did. i checked the gas and all taht...
but yet it still doesnt work. im oober mad.
I WANNA RIDE!!!!!!!!!!
so can anyone help me with this??

aight so i was out riding today and i decide to wheelie but as i do the throttle sticks and the bike just takes out from under me. after i got up and spit out a mouth ful of sand i inspect the damage and at first all i can see is that i f*cked up the rear plastics. but once i got back to my spot i look for a more detaled tiem and i realize that my forks adn bars arnt lined up right , i mean the r about adn inch of of alightment. so i was wondering if the was some easy way to fix tehm that i ddint kno about or if i would hav to buy new forks

I just bought a wr400f and i ripped the left side radiator. I was just wondering if anybody knows what models will fit with my 400. I think a YZ426F rads will work but I don't know for sure if they will. if any body knows any rads that will fit or any tricks to get one to fit please let me know.
Thank you

I would like opinions on the yz450f.I road one and there insane,but i would like to know about it from other people before i purchice one thanx!!!!!!!

Does anyone know how many turns the fuel to air mixture screw on the carb should be for this bike? I cant find anything on the internet about this bike..

I have a 94 Yamaha YZ250 I have always ridden 2 stroke yz 250's. These bikes are great! but the bike isnt good for what I like to ride! I was looking into a 00-02 Yamaha YZ426F or a 450 of some sort. I know the 2 strokes wind way out and have lots of power on the mid to top, but do the bigger bore 4 strokes pull as fast as the my 250 2 stroke does? Obviously the 2 stroke has the advantage of high winding but do the bigger bore 4 stroke pull as hard? Also I like to climb climb climb! so the 4 stroke is kinda what im after for going up hill mostly! Any input appreciated! What would the power be like?
