  1. Man I have had 2 pro-com engineering rev boxs and there new and Im having the same problem. I have to send the new one back and i got it today and my stock one starts on the first kick to. the aftermarket one doesent even fire up at all just thought i would comment on that to.
  2. I really appreciate the help I was at the end of my rope with this thing. I checked it with a light and got nothing and i've talked to a friend of mine and he's thinking its the stator im thinking about replacing it but its 180.00 so im hoping its worth thanks again for all the info chris.
  3. I have a 04 kxf 250 I would ride it and it started to die and usually it would start back up but about 3 weeks ago it didnt. I checked the spark none and I heard that the 04s had a bad cdi so i replace it with a pro-com engineering rev box still not working. I want to replace the coil next but how do you check them any help would be really appreciated thanks chris.
  4. If you have a 04 engine ice.
  5. man I have a 04 and its asome there so much easier to ride and the power is right there. I dont ride the woods but for motocross there great I went from a kx 125 to this bike and felt comfortable right away. I had a 2000 kx 250 and i rode it decent but man its so easy to get in trouble with those bikes with the fourstroke its not a problem. With the fourstroke both 250 and 450 for me personally i think there easier to back out of trouble like in the woops and stuff that compression braking helps alot. I agree with these other guys maintenance is everything and check those valve clearances hope this helps.
  6. I have a fuel screw on my 04 and it dont stay in place and it runs like crap. What are the symptons of it running bad like your talking about. I mean I just got mine and I have been turning it. I mean its really running bad and it has a new topend in to. I've only rode it for about 4 hours ran great and then took it out the last time and it made a tapping noise and in neutral i reved it up and it sounded like it hit the rev limiter everytime. Im just trying to troubleshoot this I would appreciate any info thanks.
  7. I have a 04 kx250f. I just got it. The guy I bought it from redid the whole topend and stuff and I rode it for the first 3 days total of about 4 hours on it. Now it is hard to start and I have to pull start it and then it made a tapping sound but still ran. The big question is when it is in neutral I rev it up and it sounds like its hitting the rev limiter. I just bought this bike went from a 01 kx 125 to this but ever since i got it theres been problems. I just would really appreciate any info I think this bike is asome cant wait to figure this out thanks.
  8. many thanks I will try that
  9. I just got a 04 kxf 250f and the throttle tube is sticking. I lubed the cable with cable lube and it's ok. I need to know do I need to buy a better throttle tube? Any thoughts would be appreciated... thanks.
