Sense of timing is related to repetitive body movements. Use your body to keep track, practice tapping your foot or moving your neck to a metronome.
1
Complex riffs need to be broken down into chunks that feel easy. Get the groove for those and then combine.
2
Forget the riff, first hum and sing the riff correctly on time. The brain adjusts timing through voice better.
3
If you can practice a shape on a lower tuning, do it. The brain understands time better at lower sound frequencies.
4
Your brain has to trust muscle memory to correct its errors naturally. Make adjustments without looking at the fretboard.
5
Each syllable Bo No Bo Bo is a note. Sing your rhythm as syllables first. Change the pacing of the words to match the beat.
6
If a metronome is stressful, use a -1 track, drum loop, or programmed drums. The brain likes context. Metronomes don't give context.
