Been looking for a cause for my bogging problem on 1998 powder special efi.Checked everything I could find on other threads on here. I found that my motor was torquing bad when under WOT. Also found broken torque bumper. Would this cause a bog at WOT and not allow me to rev over 7000 RPM? Any input would be appreciated as this sled has been driving me nuts for the last 2 years

Usually the motor mount broke by the torque stop.
Will check mounts today also.Thanks
Replaced front pto side mount and bog is better.I can get 7800-8000 rpm now. Pto plug is brown now and mag plug is still black. No air leaks around boots.Any other suggestions?

I would check the compression, it should be above 110 and within 5 to 10 from each side. Maybe put new caps on the plug wires too. After that you start switching injectors from side to side and also check your oil usuage. The oil pumps can let too much through and it seems it likes to flow to the mag side for some reason.
New plug boots and wires already.Compression is 120 PTO 118 Mag.Will try swapping injectors around.What can I check on my oil pump?
