Sachs 125 roadster help
 
Hi guys it me again. i have a prob with my bike their is no power in the bike and when i rev it, it seems to rev so high it takes about 8 seconds for it to come back down and even then its revs are very low and to get the bike going i have to use the thorttle over and over again to get the revs up.

So any help would be great:D

This is one possible reason

I had this last week with my 125, so it may be the pilot circuit is set wrong. Try playing with it the pilot screw back and forth, if its not returning to idle speed after you rev it, you need to unscrew the pilot screw bit by bit.


I still haven't got it perfectly set, same symtoms as you. Mine was wrong because after cleaning the carb i set it to the default setting as per manual instruction, however, my compression is lower than standard, so the pilot screw needed to be tweaked.

Not sure why yours would suddenly need changing though.

sounds like the pilot still lol.

So are you riding with the choke on now? or "more off"

revs hanging up is a symptom of lean running, but it sounds more to me like your choke is sticking.
