250r HP

[Bad Ass Honda 250r]

i have a 250r with a stroker crank, 67.50 bore, v-force reeds, twin air filter, jetted, fmf exhaust. How much HP do you think its throwing out... THANKS

[drag lt guy]

all depends on what style of porting if any at all. I would say without porting 43-45hp and with porting I would say 50hp depending on how aggressive it is.

If you dont have any porting, that stroker crank is really not going to help much. The cylinder needs to be ported to match the stroke. Porting, get rid of that fmf pipe. Get a trx-5 from esr, and a 38mm a/s and you'll put out 50

dont really believe in pipes that much... as long as its aftermarket i think your fine... but thats my oppinion

well pipes make a huge difference o n a 2 stroke a pipe does most of the work it is probably 50% of the available power if yo ucould put it i na percentage and fmf is one of the worst pipes for a 250r look at eddie sanders trx5for a good pipe setup,not all pipes are any good ..many are only shiney stock knockoffs

You dont believe in pipes? You need to read into what a pipe actually does. Its not like a 4 stroke pipe where you just get the exhaust out faster to make more power. The shape of the pipe, mainly the length of the cone, makes BIG differences. If you had a drag ported cylinder your not gonna put a PT type 6 pipe on it. You know what I mean?

well when i get some money i will look at an esr....

[Bad Ass Honda 250r]

but what about silencers? is there much difference?

No just to tune the sound.
