So the other day I was out riding and I noticed that my ride (1999 Road King) on take off that when it's at about 20 mph it seems to just top out on power. I shift into 2ndand it's all good to about 30mph and same thing, flat no more power. I shift into 3rd and it's normal, 4th & 5th completely fine.. I did compression test and they are a solid 130's. Someone suggested to test the injectors with a mood light. Anyone else experience this also? Any suggestions? Standard noid light wofk for my bike?

When was the last time you changed the fuel filter?

Maybe check your fuel pressure while your at it.

130 lbs of compression is low, that would explain the lack of power.

It was a breath away from 140 in the rear and actually 145 in the front yesterday when I rechecked it 4 times. The 130 was from the first and only check I did originally and was panicking about it. I think I didn't do it right.

concur 130 is low.. however it doesn't explain the out of power in the low gears and also the MM injection system may need the cold and hot idle set, after testing the cht, and iac... better performance in the higher gears.. doesnt make sense for fuel and air issues.. check the injectors,, fuel pressure, for starters as well as the CHT function..
