oil draining question???

i have a x12 110cc 4stroke 4spd super bike

i want to change the oil.. b/c i heard the oil that comes with it sucks.. plus i broke the engine in already..

so a few days ago i took off my body and looked under the engine and i saw 2 bolts ..both with six corners.. one of the bolt..(closest to where i would put the oil in) is big and points straight down...then the 2nd bolt is on the oppisite side and it is slanted diagonal and its smaller...

so which bolt is for the oil??...and what the other bolt for if u guys know...?

--thx alot--

here is the pic of my bike..color n everything....

One is the oil drain and one is the cam chain tesioner bolt. The bigger one closest to the oil fill plug is the oil drain bolt

thx alot for the help al300ex

Yeah...about that cam chain bolt, i took mine off (x15) and a spring followed by a long tube came out, but i ram the SOBs back in there. is that gonna be alright? some oil came out too but not much.

Ya" im a little late getting a reply back!
But make sure the bike was warmed up before you chang oil.
Should get a better bite from the clutch.
good luck.
D-out.
