I bought a non-running 2015 Crf450r from a guy who said that the local honda shop said it needed a new ECU. The bike has maybe 20 hours on it tops it is spotless. I changed the ECU and got nothing. Started to dig deeper and found out it had no compression. The nikasil (however it is spelled) had completely flaked off the upper third of the cylinder. Replaced the cylinder and put in a new piston still nothing. Swapped out the fuel tank in case the pump was bad, nothing. Checked all electrical connections and everything looks good. After a bunch of headache, finally got the bike to start by spraying starting fluid in the cylinder AND applying an external power source to the fuel pump. Once the bike starts up, it idles fine, revs fine, etc. However, it WILL NOT start without the external power source. Since finding this out, we have replaced the stator and tested all of the connections going to the ECU for a break or bad connection. Still nothing without the power source and starting fluid at the beginning. I am lost at this point as far as where to look next. Any suggestions or tips would be very much appreciated.
read up on past posts and got busy testing my buddy's '00 drzS which runs it's battery dead when ridden.new rectifier and all connections checked over(so he says) so i unplugged the three yellow wires from the stator that go to the rectifier and probed them with the multimeter (red) and grounded out on the motor(black) and got plenty of resistance.what do we need to do next? what does the parts man need to charge us for this time?
hi there, I recently bought the ricky stator ltz400 stator after having seen a post confirming that after soldering the old harness on the new stator worked.
unfortunately, after I completed my work, the bike no longer starts. im really not sure where to start. I unplugged the connector with the blue/green/white/grey wires from the box under the seat, and managed to test the blue/green resistance at 0.52 on whatever resistance scale my meter was on. I did not test the black/white wires.
the battery is fully charged, the main fuse is intact, the starter runs strongly, the bike just doesnt fire.. it ran fine before taking it apart, so im sure i've messed up the job somewhere along the line. Im going to recheck to make sure I didnt reverse some wires along the way. That cloth insulation is annoying, I finally ended up using an exacto knife to carefully trim it off.
Anyone having or had problems with the starter not turning over easily on the 450X???
I have read about this problem on CRF's ONLY and not seen anyone come up with a fix.
Problem being is that you think there is a problem with the battery, when infact the battery is OK. When you have a good fully charged battery in the bike and press the e-start, it turns over very slowly.
I have checked the electrical circuit and it seems OK. I am wondering if it might be the starter itself - any suggestions?????
For my 2001 XR650R
Searched around, and found some information, but I need a little more.
Looking at an after market tank, which works best? I plan to go with the red, and would like it to match the OEM color. I will be running a Scott's Damper, probably. Any clearance issues?
What range are you averaging with a 4.3 gal?
I have considered the seven gal behemoth from acerbis, though it looks too wide for my tastes. Though extra fuel is good, but adds weight. Yes I know you can run it low, so why not a smaller tank?
I've had natural colored tanks before, but I'm not racing so no need to check level, on the fly.
Pictures would be great!!!
Anxious to find out what the BRP heads are using, and what works.
