Need parts info for g14

[BamaG14]

I am going to put some new rings and bearings in my 1996 G14A after the hunting season is over here . My cart S/N is JN3211818 so you know it is a 1996. I have conflicting info for this cart as for part numbers and the cc of the motor. My service manual says it is suppose to be a 300cc but on some sites states it is a 301cc. Parts might interchange but don't know .

I have already pulled the head and put new valves,springs,seals, and lapped the valves which got my compression back to 170. It just smokes too much on start up so oil ring is gone . Reason for new rings. When I had the head off there was no marking on top of piston and cylinder looked good. I am not sure if it is a standard or not . There are three different sizes in some parts lists so I need to know for sure when ordering . I guess measuring is the only way to know. Also there is three size rod bearing to choose from . How would I know which of these is right .

Cart runs great . Have put a lot of money in to it with Plowman's performance kit,new starter -gen,solenoid,reworking head,light kit.

So I need some advice on the right part numbers so I don't go wrong. I saw a parts rebuild list on here for this motor before but can't find it in search.

any info appreciated
