Workshop Manual Recommendation

[BearFish]

The son of a friend has an old dirt bike that he is wanting to get running again. I am going to help him with it but have very little experience with this kind of mechanical thing… so am looking for a workshop manual to guide me a long.

The engine is a 1P54FMI - are there any workshop manuals available for this that would be suitable?

I have found two possible ones, both from Haynes:

Pit Bikes - but this one references the 1P52FMI - Lifan 1P52FMI Haynes Repair Manuals & Guides

Chines 125cc Motorcycles - but this one references the 154FMI - Giantco Bronco 125 Haynes Repair Manuals & Guides

Which one of the two would be the best to get? Or are there any others that I have missed?
