how many cc's would 80 over be in stead of 660

 

Im confused [img]i/expressions/face-icon-small-sad.gif[/img] 80+660 = 740 80mm over would be a 180mm piston which would be alot of cc's nearly 2x stock size, I have no clue what you mean though

 

when mechanics say just the number they usually mean thousandths of an inch. 80 over would be .080" (inch) over bore.

its 687.0746248116038


*************************Formula
1 inches = 25.4 millimeters

pi/4 = 0.7853982

cylinder volume = pi/4 x bore^2 x stroke

stroke = displacement / (pi/4 x bore^2 x number of cylinders)

is there anything u dont know 007!

 

Warrior007,

Just too be picky, your calculation of 687.0746248116038 cannot actually be that precise. If you only measure the bore and the stroke to three decimal places (102.000 mm x 84.000 mm), then the first number has six significant figures and the second has five. Therefore, when multiplied, your answer can only have five significant figures meaning that it cannot be more precise than 687.07 cc's. Just a technnicallity but a major ordeal in my line of work.

Sidenote: By the way, the miscalculation of significant figures was the major cause of the overshooting of the runway by the enterprise spaceshuttle in 94. Not that atv's are rocket science but the rule still applies to the measurements.

UM? 2+2=4

 

The ramifications of your precision multiplication are astounding HoundDog. Thank you for being so astute!


But seriously, I just used a displacement calculator I found on the web, so im not that smart, just know where to find the good stuff.

 

i wouldnt have admitted to that.. you had everyone thinking you were a genious.

 

what is a blaster bored 40 over. i can't wait till i get the big bore kit. i have the money but just enoough i have to work more and save up and then you know. i got a fiance it's her lol

 

i dont know about the blaster, youd have to find the stock bore and add .040 i believe. (its on yamis website in the specs section of the blaster. i know its in there im just too lazy to look it up, sorry. but ill give you a link to save ya some time) blaster specs
