93 SL750 the front cylinder compression at 30
The front one was at 30PSI and the other two were at about 110 PSI. What does that mean and what is involved to fix it?
Thanks for the help
I just changed the fuel pump to a triple and all the fuel lines as well

Hi Rob,low compression means things in the cylinder are not right.
You need to remove the head and look inside,Please post some pictures,it will help with the next step.

It means you most likely didn't change the fuel pump soon enough....
My guess is a hole in the piston.
Remove the head and have a look.
