My guess is that a +4 crank is stroker crank +4mm. I do not know the c.c. gain on a 4mm stroker crank but am sure someone here does.

if you are going to split the cases and add a +4 crank, you might as well add a 102mm piston. that would make it a 719cc engine.

the crankshaft on the raptor is not the same as the one on the rhino.

Yes i have seen the kits on ebay sleve,piston,crank,and gasket set 500 us dol seems quite reasonable as i have just got a price from yamaha over here and for the stock crank and bearings they want 1530 us dol.

Thanks for that info!

I forgot to mention all the shops that i have called over here say they never split the cranks they just fit crank kits in and throw old crank away!!!
mmmmmm if i could find a easy method i think i have just come across a good buisiness!

another silly question from a brit
I have heated the crank up to red hot with oxy torch am i right in saying because this part is a moulded steel the molecular structure changes when heated basically making it weak? The reason why i ask this is the even if i get it off i dont want to put this back in in case it throws the piston through the head.......
And before i get a ribbin from pips i looked this up online as i wanted to know how much cast expands heated apposed to machined ie the centre pin.
my bug has only just covered 800 miles but they wont do it under warrenty because i have changed exhaust, modded carb, installed cdi unit, all of which the shop sourced for me!!!! what a kin wan*er's they are........................................

I would not get a "hotrods" crank, they are terrible.

I would also not do a stroker motor in a rhino.

e:mail [email protected] or call him at 760-484-0986

best in the Biz for RHino motors. he can get you a crank and other performance parts that will last and give great power.
