Compression question

[BooTheRedneck]

I have another question about compression.  After the bike warms up, my compression results are:

#1 = 150 psi
#2 = 135 psi
#3 = 120 psi
#4 = 145 psi

Are the numbers too far out of whack?  When I put a teaspoon of oil in #3, compression goes up to 180.  I dont want to rebuild the engine, so do ya'll have any advice?

Boo.

Rule of thumb is 10% of each other. Bad rings if it comes up a lot wet.
