250 and 300 HP stock?
With good clean proper jetting, what kind of HP do we think the 250 and 300 is putting out? I know it doesn't matter, but I am curious.
I did a search, but surprisingly nothing came up.

???hp
I'm pretty sure theres something around putting them both up there pretty high Now this is my memory which has to be taken with a container of salt ....
but I think the 250 was listed at 48 and 300 at 49 Its out there somewhere..... I think Corey (smartcarb) could tell us what the numbers are for real |

Ive found various quoted figures; all right around 45-50hp for both the 250 and 300 engines.
And both are supposed to be very similiar hp wise, its just the 300 eclipses the 250 with its extra torque......

I ran our 2004 DE300 on a Dynojet Dyno up at Finish Line Engines in Beaver Dam, WI. The engine had about 8 hrs on it following a completely rebuild, (replated cylinder, new piston, rod, bearings, etc). I did some minor case and port clean up, it has Vforce reeds and one 0.014" base gasket. The bike is jetted correct and it runs very well. It made 40.2 HP to the rear wheel.

dyno
theres a youtube video of a ktm 300 that makes 45 with the apt
If Corey gets back on here again he could give us real #s on current bikes I would think with all the gasser testing they did I bet they must have run 200s 250s 300s I wonder what the drivetrain eats up ? 10 % -20% 40 at the wheel would be what at the crank ??? Zman was your head done too? I'd be curious to see dyno sheets between 250 - 300 I'm more concerned with torque as I'm a slightly larger guy riding a supposedly porky bike I ride a 300 and a 250 and my ass dyno says the 250s hp is equal and easier to make but the 300s torque gets me up hills with less work But all my 250 bikes have had different characteristics screamers -chuggers |

Unfortunately when your 6'1 and 235lbs, you forget about the little 200....
