if the CDI, ring,pistons are not blown out then you only need to do cosmetics changes / clutch plates .. bro .. it will be a treat in 1.3KK. ,
Maximum kharacha I can imagine should be around 20k, if no big problem like CDI Unit or Ring/Piston/boring are working already.
are these 97' Model ? if yes then I am pretty sure these must be good inside, not like those 91 and 89 models which where totally scrapped
