This is a link that you can find your exact engine displacement. All you need is the Bore and Stroke. Make sure you select the correct unit of measurments.
That works pretty good.
or you can do it the old fashioned way.... bore X bore X stroke x .7854
example:
74.00mm piston 57.3mm stroke (250X)
you move the decimal left one number.
7.4 X 7.4 X 5.73 X .7854 = 246.4387 CCs
i have a 350 honda trxtm i was ridding it just cut off could a coil go bad like that i did pull plug and turn it over look at plug no spark some one help
Welcome to the forums.... CHeck for anything that may have came unplugged. or a blown fuse. a coild could quit without warning but generally they will work when cold and when they get hot they start to fade away.
Yea I know I dont understand that lol why call it a 250? call it a 230cc... but using that calculation with my stroke, 62.2 mm i believe, and the bore size 69.4 (biggest piston i found on bike bandit) it came out to be 235. but while typing this message it occured to me that that is just the piston size not the bore, but bore wont be far off lol
Well this guy has a jemco exhaust for the lt250r for sale just wondering if i should pic it up or stay with my fmf ?
