mmmmmm....
almost like a 4-stroke


how about a bigger carb like a 38 airstyker

HP doesnt mean everything, its all about power curve. It wouldnt matter if you have a motor that makes 120HP on your LTR if its not a good power curve/TQ it will be a pile. If he is set up correctly he shouldnt have much of a problem with your average everyday 450 or shee rider. My LT is probably only making 40's HP and I've yet to have a problem at the track with a 450 or shee that wasnt running drag ported or big bore/stroked motors.

so if i set it up this right
i shouldnt have any problems with the average piped banshee or piped 450's

I've ran close to the same times on a track that some ported/piped shee's do. never once been beat by a 450 up there though.

i agree 100% peak hp is pretty menaingless... its just an expression of torque at a given rpm
,pipey bitch that hits a high number usually loses ot a bike wit h a broad curve that pulls strong holeshots .. those mods you listed are not know for big numbers btw ...mild pipe and carb

so then a 450 would probably win, because theres way more torque

all i know is my piped and filtered LTR is way faster than my ported stock cylinder R on race gas, the torque on the R just doesnt even compare

Well I Would Say A 4mm Will Work Better Because It Will Pull Harder Down Low And Mid And The Top Still Will Be Strong.. The Trx 450 With A Stage 2 Web Cam And Pipe Is Really Close To 50 Hp But It Makes It At 9-16000 With The Right Valves Springs And Such And Gassrx Dyna Rev Box Settings .... On Short Tight Tracks The The 250r Stroked Will Eat Them Up But Long Straights.. To Much Rpm Difference To Over Come.. Plus The 450 Has More Torque More Traction It Will Be Tough,, Oh Yeh The Shee The Same Just Get The The Shee On A Moto0cross Track Lol Lol Just My 2.2 Cents Worth

Pt With A 38 Air Stricker Or Es Pipe

negatory theres loads of torque on your 4 poke sure but just available at a lower rpm the 250 makes great torque except higher

wel l that may very well be the case but that doesnt mean your 250 is setup correctly or your porting is anything great a good running properly equiped 250 can ru nwit ha 450 all day in the rigth hands
