Can anyone tell me how to rebuild a runner sp125 engine or is there any guides on here that tells you as I have had a look but can'nt seem to find anything. any help would be great.
if you need to ask you shouldnt be atempting it where are you located there may be someone nearby to help
u have to split the case's , change main bearings-seal's ect , but if u have to ask then ur probs gonna fuck it even if u get a guide , take it to some1 who knows what there doing watch them and learn. then when u feel u can have a go @ it urself , have a crack @ it but untill then id leave it well alone... :thumbsup:
