just wondering. in the last year i have noticed it being hard to shift out of 2nd when in the high revs. i have to completely shut off the gas and let the revs come down before it lets me shift. it seems to only do it in 2nd gear when revving hard. what do you think could do that or cause that.

my friend had the same thing happen to him in 09 on his kx250f, but the crank was hanging out of the cases more.

i think we did the crank/ top end in like late august, took the winter off. then we replaced the topend in February.

That's wierd man, maybe it's those first year of that body style KTM's. I know the first 144's had crank problems that they later addressed.

I've got an 09 250sx that I ride at tracks pretty frequently, and race now and again. I like to wring it out too. I'm still on the stock top end and clutch! it's getting tired though.

I mix it 60:1, following the manual, while using fully synthetic pre-mix and 92octane.

ive actually been starting to wonder the same thing. maybe its just that year.

the only reason i say my parents is because my dad races to. so he races a 4stroke and he cant ride 2strokes and wont. it also doesnt help im 195 pounds and a 125 is going to be hard to carry my weight and they both just want the best for me. and the only reason i would get a 250f is to race the national. and i would probably still race my 250 2stroke locally and for loretta's.

so here is what happened at the track...

i was going out for the 4th practice of the day, i warmed up the bike good then took a site lap around the track (check lines and continue to warm bike up) i did one hard lap and as im coming to the finish line section the bike bogs i would say 3 or 4 times, so i pulled to the side of the track to try and keep it running but it bogs out bad. i tried starting it, check compression with my hand, everything seem good. i pushed it back to the truck, we then took spark plug out to see how it looked and to check spark, the plug looked black, we put a new plug in. it fired up 2nd kick. i warmed it up listening to the motor sounded fine until you got to about 1/2 to 3/4 throttle and then it had a big bog. the bike kinda sounded like if you were to start your bike with no air filter. i rode it in the pits to see if i could feel anything and listen to it. it didnt want to run all that great so i put it on the stand and got undressed and took it to the guy who builds my engines.

now the thing that gets me is. if it ran when i took it to him, how does something claimed to have that big of damage run? now im not bagging on my engine builder (family friend and he has always been there to help me) at all im just confused.

i talked to my dad this morning, i have a friend who has a 07 ktm 250 (same bike) and we are going to try and barrow his for the weekend and have mine rebuilt, just with how money sits we might get a newer 250 sometime in the summer.

i would love to be the guy who trys to qualify on a smoker for some of the nationals, but as it being my first time trying to qualify i want to do good and i know as long as im not paying for all the entrys with my own money my mom and dad will want me on the 4stroke. now sometime in the near future when my mom and dad stop helping out, i will definitely try on the smoker. but just knowing my mom and dad i know it wont happen if they are paying for it.

1000 dollars... its about 700 bucks to get a cylinder and piston, thats with my discount from ktm munn racing. we might still have to replace the crank. not sure yet.

well me and my dad usually do all the bike work during the week. we usually change oil ever 2 to 3 rides airfilter all the usual bike work, since its 4 days before the loretta lynn qualifier we took it to my engine builder to have him go through it. he said he found some dirt, which broke the reeds, and then the reeds got sucked into the cylinder and bottom end. so all in all it was a snow ball effect. its ok. i talked to my mom, we are either buying a 2011 250sx, which there is only one in washington, or we might get a 2011 250f so i can ride the national if i get my pro points in time, and fix the 250 2stroke to race and practice on.

Are you doing the work yourself? I would consider getting the cylinders repaired and replated for much less than an OEM replacement cylinder.

But I can guarantee a 4T will be much more costly if you frag it.

But I have to wonder why you are having so many severe failures. Something is off; jetting, air filter maintenance, incorrect pre-mix, something. I know a lot of people that race two strokes, fast guys, and they do not have catastrophic failures like you are having.

and when i said its not that much less then a 4stroke i ment over time, ive gottin 2 years out of a 250f, and it cost us 2500 to replace almost everything when the crank went out. i love 2strokes, i will always have one and race one. im just confused on whats going on.
-jetting is good, runs fine
-change airfilter after every ride, sometime mid day on super sandy/dusty tracks.
- trick 114 with 927 premix, at 44:1 sometimes 50:1

well this saturday i destroyed a motor for the 3rd time in 2 years.   as much as i love 2 strokes everytime it blows up it costs 1000 to rebuild it. thats not that much less then a 4stroke.

for some reason it always destroys the cylinder.
