What does the engine do when you have broken a Valve Spring? Does it miss slightly at higher Revs? Run Richer at Higher Revs? Run Worse on SPray?
WHen I had my Rag apart, I changed the Exhaust Valve SPrings to the Stronger ones from Stock that I was using on the Intake side. I looked at the Intake retainers, Shims and Buckets along with the Valve heads and saw no problems. I took the #1 Intakes out and everything looked fine and for SOme Stupid Reason (I had the Time) I did not check the SPring Pressure or take the other apart.
Now it is back together and running exaclty like it did after the explosion.
I took the SPark Plugs and put it in My ZRX and they ran fine.
I just re-checked the Valve adjustment and the tight Intake is .001 tighter than specs of 0.006 and the Tight Exhaust is 0.001 tighter than the SPecs 0.009. and the Lose ones are in specs of 0.010 exhaust and 0.008 .
SInce the Cams use a Press on Sprocket, one of my thoughts is that maybe the cams shifted slightly during the event. So I plan to check the timing (If Possible in the BIKE tomorrow and push against each Intake Bucket to see it I can feel any variation in spring pressure.
To me, the Bike seems to be slightly retarded and rich. While revving it in the back yard prior to changing the oil, the Pipes got hotter than Usual just like an engine running retarted and /or Rich!
It is always something and I cannot imagine how something electrical could have fouled up during a Mechanical event! Is it possible that it was an electrical problem that caused the event to begin With? I plan to change the ECU, Bypass the PC3 and Schnitz Controller just to make sure!
