been trying to fined out wat engine is in my quad I no its a 4stroke semi auto 3 gears and reverse believe to be a 110cc im thinking loncin ?

 

 

 

 

Probably parts on it from multiple atvs, that thing looks like its made from 5 or 6 different machines.

 

see the thing is it jumps out of 1st and 2nd gear 3rd works fine thinking I might need to see if I can get a gear box for it been told its a loncin engine but cant seem to finde gear box any where for it would the shaft drive make it jump out of gear on 1st and 2nd but fine in 3rd if some think was wrong with it all so can I just get a new shaft drive engine as cant finde any for sale at all thanks
