a bit o help

[lilhudi]

i ordered a 49 cc slant head 4 stroke engine .
i havent recieved it yet but am quite excited.
i have looked at all the photos and discussions and after looking at my bike i see a problem. the wheel i have in the back of my bike has a odd bearing system i took it all apart for the heak of it and realised that im going to have a problem mounting the back gear.

maby the instructions will help me out .
but i thought some one might have had this same kind if issue

also any bits of mounting advice anyone has would be nice
