Title: Kymco people s 125 crankshaft.. Urgent help needed
Post by: kymcop125 on August 22, 2011, 11:07:26 PM

Hi all,  :)

Currently I am disassembling my kymco 125 engine as it has a strange noise (found oil level low)  :( and thinking it might be the crankshaft bearing (shell).

Can the bearing be changed separately or I have to buy a complete new crank?
Where is the best place to buy parts cheap, I live in Malta Europe (near Sicily)

Thanks any help appreciated.  :D

Matt

G'day kymcop125, this is not much help to you but, I don't think they used shell bearings on these engines, I believe they are roller bearings. You can get them rebuilt, but it is a specialist job, certainly not something I would try at home. I don't know about the 125 engines, but for the smaller 50cc engines you can find crankshafts from various aftermarket companies, I bought mine from an ebay seller who goes by the name autotech355, also uses Dr.pulley886 as another user name.
Have a look around, if you can find one it will be a lot cheaper than genuine.

Are you sure the noise is from the crankshaft? It would be easier to check the top end first, and cheaper.

Probably , as I already checked the head and valve.

thanks

Hi kymcop, can you describe the noise? there are plenty of other reasons for rattles etc.
