stock bore hp numbers???

[ALL-BLACK-1000]

I'm wanting to know what type of hp numbers you guys have seen out a stock bore high compression pistons motor with built head??? and is a lee's stage 4 head too much for this this type of set up??

I've heard 200+ is possible on the right combo

First.....What year 1000? and second no where near 200 hp lets say 08 gsxr 1000 it would be about 180-185 hp

ppl get 180+ out of 07+'s with head/cams only. build it right with high compression and 200ish is possible imo.

I agree.

what did the ama superbikes make? i thought it was close to 200hp but they had unlimited money and resources.

Figure out what time you want to run and talk to the builder of your choice about what engine combos he has that have succesfully ran that ET. I promise you this will be the most cost effective route to success.

My 06 made 187 on mrxo1 after the head and cam package with stock bottom end so gettin close to 200 is achievable

my 08 made 193 hp.

I made 201 and 121 lbs of tourqe with 1397 je pistons mill head and 2 intake cams on my 02 put in windage trfay remove counter balencer add oil pump gear mill head thin head gasket cheaper than head and cams unless you get a hook up on head work.Becouse of cam profiles this motor is easy to ride and leave on

oops....double post.

Our 08 AMA Superbike standard bore/stroke made over 200hp....and we regularly build replicas for customers....within a reasonable budget. With no budget limitations, 220hp from standard bore/stroke is done all the time at a factory level.

That being said, it is much easier/cheaper/reliable to make the power with displacement.

I guess I stand corrected but if you build one come back on here and let us know how you make out
