Hi new on here anybody no we i can get any info on .my 90cc 4 stroke quad .like manuals.

 

Make and model would be a start, but even then few Chinese makers produced any sort of manual for their products. Most 90cc four strokes use either a copy of the Honda 90cc engine, so manuals for Honda 90s would work for the engine, or a GY6 scooter engine, these are fan cooled and have belt drive automatic transmission. There are a few Chinese/Taiwanese makers who put out on-line manuals for these.
