hahaha nice man

ok...the stroker is a bore stroke combo...it puts out more power that just a regular 440....a 440stroker(like i have) is either bored 20 over with 40mm stroker or bored 40 over with a 20 mm stroke

[ill_lil_romey]

So a stroker can only be Doibugu2 or a 440 ?

[nick23]

what?

Stroker kits involve lengthening the stroke of the motor by way of a "stroker" crank. It gives you longer piston travel (up and down) and typically gives you more bottom-mid power.

exactly

So can you run a "stroker" 400, 416, 426 ?

nope, lil romey if u stroke it increases size of cc's/ so if u stroke a 400 which is actually 397 u get 422 i beleive . some one correct me if im wrong on that cc size . and if u stroke a standard bore it makes the bore too long for the bore . not a good combo . its best if ur gonna stroke it to bore it some or have it resleeeved to get the stroke /bore ratio back where it needs to be . a stroked 416 is a 440 like some one sadi above . a 440 stroked is a 465 :)

The final cc size depends on how far you stroke it. For example a 76mm bore 330r stroked 4mm is a 350. A 8mm stroker on a 330 bore is around 380. A 4mm stroker on a banshee 350 is a 370, where a 10mm stroker is a 450.
I'm not sure how far the 400ex stroker kits usually are. 4mm is pretty common for most bikes so it's probably around there. I know with a 250r, if you stroke it more than 4mm you have to trench the cases (so the crank won't smack the bottom of the cases at BDC).

i wun a tru 440stroker

If you need questions answered can an engine builder, Spark, TC, FDO, ect. There are different stroke lengths, rod lengths, basiclly there are different combo that you can go with. Some work better than others, so do lots of research. I would suggest talking with Mike at For Dirt Only. That is where I got my crank. I have a 426 bore that is stroked 6mm, to give a 463cc. Let me tell you this thing ripps! :blah
