Hi,
New to this forum so hello. Hope someone can help me. 2003 XP DI
First I recieved the 12Vlow message, charged battery and all good for a bit. Then a few rides later was running part rpms and was sluggish. Tested the battery and when reving it I noticed it jump up to like 18V. I replaced the voltage regulator. Took it out tonight and it revs out full and everything but does still not seem to be running 100% and hesitating a bit.
Brought it in, removed the plugs and one fell apart (ceramic cracked) and the other was cracked in the ceramic. And they were also really black. Usually pretty toasty brown.
SO I replaced the plugs with new ZFR 4F's.
Took it out for a ride today.
Starts no problem. It hesitates just off idle to 4000rpm and then when held open it seems to pull hard with no hesitation (seems alot better than before the new rectifier, top end that is). Didn't hold it open for more than a few seconds then when I let off it wants to die and bogs right down then will pick up again at lower RPM. Did this a couple times then I went in. No warnings or beeps occured at any time.
Removed the plugs and the MAG side plug was bent and touching the center electrode. Both plugs looked almost new but were pretty white on the ground electrode. Compression is 130psi both sides.
What could cause this damage to my plug? Detenation I assume? Limp mode? Was the rectifier not the cause?
