I just got done totally rebuilding a 2014 kx450f I mean all new everything on the inside of the motor. But now the bike won’t start on its own. But it will start with starting fluid and then it stays running untill you shut it off. Could my fuel pump be going out or could my ECU be bad? Iv had different people tell me different things. Bike also has a bit of a misfire when your trying to keep the throttle locked at a certain point. This is my first fuel injected dirtbike and I’m not sure what to check first and or how to check it. I put a lot of money into this bike and I just want it to run right.
My rear brake does not even stop my rear tire from the slight rotation while in neutral, revving the bike. I have replaced the brake fluid with the DOT 4 (suggested Suzuki brake fluid), bleed the line countless times, and still to no avail, absolutely no brake. So I believe the problem lies in the caliper piston? Has anyone ever experienced a bad piston?

Hi, I am 13 years old and I am trying to decide what bike I want to get (two stroke of course). I'm 5'2 - 5'3 tall, and I weigh 125lbs. I'm a beginner at this, meaning this is my first bike but, I have ridden a dirt bike a few times. My choices are the yz85, cr85, kx85, kx100, sx85, and the sx105 (Yamaha, Honda, Kawasaki, or Ktm).
I am not interested in the rm because I just don't like it. It seems like a cheap crappy (sorry if I offended you) and it doesn't seem to have the speed and power that I want ( at least that's how people describe it to be). So please don't include it in.
I am going to buy a used bike on Craigslist or somewhere because this is my first year and I'm not the richest of families (in case that helps.)
Right now, I'm confused about which bike to get because they're all good brands. I want to be fast on the track (obviously) and I want to be aggressive. Which bike will fit that role? Can some also explain what top end and bottom end power is and what it helps with when you are listing a bike? Can you include the pro and con of it?
I'm also not sure if an 85 is the right size for me, as I want to grow into a bike and have it last me. Maybe I should get a 125, if is so, which one (again, no Suzuki rm)? I'm going to a dealership to sit on some and try some (not too sure about trying some) Saturday but I just want thoughts about this.
I don't know ANYONE with a dirt bike so the internet is my only friend here so I am really counting on you. My mom doesn't know anything about dirt bikes or the sport so I have to really look at this stuff myself. If you have any tips, please leave some as they will be helpful for me or any other onlookers in the same situation as I am in.
I'm located in the greater Atlanta area, and am looking to purchase a Kawasaki KDX 220R trail bike in excellent shape. I will travel if needed, but I prefer something within reasonable distance of the Atlanta, Georgia area. Let me know what you have, guys. Thanks!
Hello all, its been a while since I posted, felt sort of twitch today, so I thought I would post a visual story of the journey with my KX250f.
I purchased this bike off a guy who had NO BUSINESS owning it. Rode it on the street (bald tires), plastics were completely jacked up, seat was barely hanging on. The topper was that it wouldn't start. So...I got the bike for a REALLY good deal. I always wanted a KX, so I had to jump on it.
Mechanically, the intake values were WAY off, thus it not starting. While I was tearing into the bike, I went a head and replaced the piston, all seals, etc. The crank and bearings were good. Along with the complete cleaning, I wanted to bike to look amazing when it was done. I always find myself not only reviving a bike from it's bitter end, but I make it look so nice, that I consider never riding it! Yea, I know, I have a problem. None the less, it got a ton of cosmetic upgrades, etc. Thanks for everyone who helped me through the process. Especially, my family and particularly, my son JP who is learning more and more about motocross.
I am completely in love with the DCorVisuals Lights Out graphic kit. The matte finish looks so amazing....Thanks Jeff N. for working with me on getting this kit made for my bike.
I did the best I could in ordering the pics in the chronological order...the first 2 are showing the bike to me while I was talking with the seller. Cheers!!! If you have any questions, please post them here and I will try to answer them as quickly as I can.
