Hey guys i recently bought a 07 yfz 450 that had hot rod piston cylinder and crankshaft , hot cams , dyno jet carburetor, yoshimura exhaust, k&n filter and racing clutch and now removed the piston crankshaft and cylinder and placed the stock ones, will there be a huge effect on the speed and power?

You'll notice a decrease in acceleration but your top speed will remain the same unless you changed the gearing. You may have to re-jet the carb to get the most potential out of the stock components if it was tuned for the aftermarket parts you listed above.
