different teeth on clutches

[hotroded]

i have a big sproket on the rear of my mini bike , its supposed to be 72 teeth i think.
i just recently i picked up 3 different clutches 12, 13, 14, teeth .
how will this change the ratio on my mini bike up or down ?
i know the smaller gear in the back is supposed to make more top end.
am i rite about that or wrong?
thanks
total confused:doah::crying:

You are correct. The smaller rear or bigger front will give more top speed but slower take off and less hill climbing ability.

so what if you have a big front sprocket and a big rear sprocket ?

if your on flat ground start with the 14t clutch. It will give you the most top speed and less take off. But its a very subtle change changing up or down a tooth on the clutch . a 12 72 ratio on my 5hp bike will take my 160lb butt up a straight up hill from a stand still with ease. So youll be alright

yea youll still get up to a pretty good speed with the 12t

If you do a track you will want the 14 and 72. Hills or take off you need the 12 and 72.
