Question

i was wondering if u install weisco piston (0.80) over does that mean u r boring ure quad 80 over or wat because i was gonna buy the for my kfx but i dont want to put something on there that is gonna give my atv a chance of blowing up

Answer 1

.80 over is excessive overbore. You should overbore just enough to put the smallest over size piston you can use.  

Answer 2

Yes, .80 over means that it will increase the bore .80".

You will need to get your cylinders bored to accommodate the larger piston.

This is both good and bad, the good is that it increases the engine volume (cc's) that bad is that if you ever have problems that scar the cylinder walls you will have to get it bored again, and usually .80 is the largest over bore you can get. So you will have to get the engine re-sleeved.

If you insist on going with an over bore go with a .10 or .20
