no one said it was impossible. what was said was most will let go and it's not smart to run one a complete mile wot without backing out. again let me point out the facts.

 

even if you had the gearing for a load through the whole mile you don't have the right domes, jetting, compression, timing etc

 

not one single banshee on this site is setup to run a mile. if it was it would only be a mile bike. it would not perform at any rpm other than wot.

 

look at the weedeater..... ever seen a weedeater make good power below half throttle? nope..... it's tuned to run cool wot and not exceed a safe rpm

 

sleds/snomos ever seen a sled that made it past the load the clutch setup and tracks put on the engine? nope.... well maybe the few that have went way beyond stock hp and ask them guys what happen when they get held wot for long long pulls...

 

waverunners.... again they never lose the load against them unless the loader loses contact with the water. then a rev limiter kicks in.

 

 

 

OK now lets look at what it's going to take to make a banshee safe for mile wot pulls.

 

the absolute tallest gearing possible to keep a load against the engine

 

high squish clearance. i would guess 55 plus

 

low compression

 

low port timing or a rev limiter

 

a pump or modified fuel delivery

 

OK now please tell me oh so smart banshee gurus.... what kind of power do you see this setup making on the power curve? 1,500-6,500 rpms?

My weedeater pulls about 16000 rpms.

your weedeater was also seeing a load against the grass and length of string. as a banshee rolls faster the load is reduced. hold your weedeater wot without string and not hitting grass for a minute solid.

 

i have burned down several weedeaters over the years by holding them wot for hours at a time around ponds etc

You must have a gallon tank on your to hole it wide open for hours lol

I feel like I could hold it wide open off the ground for as long as I want?

You keep bringing up no load on the motor high gear. It doesn't take 19/36 gearing to provide the load. At a certain point, aerodynamic force provides all the load needed & then some.

 

Phelps, I think you get it, but some other's; I have my doubts.

i have never really ran a full fender bike so yeah my opinion would be void for sure on wind resistance, but in the case of any bike i have owned wind resistance never over powered the engine to the point it held load. i have never owned a bike that would go more than 1/4 mile without running out of gear or rpm either. most of us set our gearing up to where it matches hp/tq that's why my bet yesterday was a untouched bike. a 40hp bike will more than likely have stock gearing and a 100+hp bike will have quite a bit higher. what im getting at is with added power and added gearing final gear should pull all the rpm's without anything such as wind resistance effecting it.

 

my drag bike was only a 5 speed but at 109mph it would run out of rpm and lay over to the point if i held it it would burn down no questions asked. why? because it was tuned to make power throughout the rpm curve. by tuning for that it will build heat if held wot and eventually deto and burn down. you can't have both. safe wot tune and curve power.

 

 

i could almost see a bone stock banshee with a better dome design running a full mile with a heavier rider. mainly because the pipe flow, heavy rider, full fenders for wind resistance and a dome design that wont trap heat running it wot. half the members here couldnt tune a one key piano muchless a banshee and nothing against them (that's why we have builders, dyno's and afr meters) but some of those members are the ones in here arguing the point.

 

i think the op jumped out once i said prove it with a video because he knows he has never held it wot without backing off a tad, or letting out from time to time allowing heat release.

 

 

 

 

 

 

back to the weedeater. no i dont have a 1 gallon fuel cell. i mean running it constant and only stopping for fuel. a cheaper trimmer will only last a season if lucky. a echo being a better brand will last 2 season. either way no one runs one wot without a load otherwise they would not be trimming grass or running it longer than 20 minutes before it eats shit. echo didnt design the trimmer to be ran without a load. they know when you're wot your trimming grass not waving it in the air in a rock band video.

i should probably add in one more little detail. most lawn care products have a mechanical gov that will bring the wot speed down. remember your gokarts that you took the arm off the side of the carb so that it would rev higher? remember how it went to smoking shortly after that and you killed the rings? basically you would get the same life out of a banshee if once the engine reached max rpm you cracked out of the throttle 10% and held it there.

All RPM, gearing and wind resistance aside...

 

I want to see a Banshee at WOT for a mile. As said before, I will add a BHQ koozie and some stickers to Phelps $100.

 

A lot of people in this thread act like it's no big deal and that they do it all the time..

 

VID or GTFO!

my bet was a one day bet. BUT if tyler is still willing to offer up some free gear i will offer up 20 bucks to the first legit 1 mile pull. you head out to the shop and start doing mods that will allow the mile pull safely i will tell you to get fucked. the bet is that "your banshee asis" will do it because you do it "ALL THE TIME"

You really are an idiot.. For the reading impaired out there..

 

 

A few days ago I was in the chat room and some people in there where talking about how u can't hold a banshee in 6th gear wide open cause it will blow up. I have been doing that for 10 years and never blow a motor. So my next question is y do people think u can not ride in 6th gear wide open???

And then it became more specific, because the original poster omitted the running at WOT for a mile..

 

 

we were discussing holding a banshee wot for a solid mile. you post a video of you doing so and post your mods. i want a video of you holding the throttle completly open for 1 whole mile and never backing out not even a little bit. if i hear a drop in rpm's for any other reason other than it seizing down you will prove me wrong..... unless you run a bone stock bike i think i know the outcome.

And then, the original poster talks about running his bike at WOT for a mile..

 

 

 

Wow after all the these posts and no answer It seems as though windy might understand what I'm getting at. Someone please explain to me WHY you can't hold a banshee wide open? Now I know and have people who will vouch that I have ran a mile WOT, hell probably even more. So please voice your reason as to why its impossible. And who's this locotaco guy, does he think he's the shit because he bought a site?

This is just for information only. We don't run a full fender bike either & I know the affects of wind resistance. We run over 120 mph documented & the ET to MPH ratio is off. Mainly due to a quad not being aerodynamically effecient.

 

We have ran full throttle in high gear for about 1/2 mile for aerodynamic testing & future goals. There's a point with a given HP, gearing, wind resistance/drag coeffient & I'm sure I forgot something.  That limits the RPM of the motor or the MPH for a given vehicle.

 

Our quickest runs with the quad in the 1/4 mile has come running out of gear & RPM. We shift into 6th gear well before 660'. Our final RPM on a good run is 10,600 & hits that or maintaines it well past the quarter when staying in the throttle.

a 2 strokes et and mph will never add up to nhra standards. be it resistance or lack of torque idk. kinda like a toyota supra traps 160mph but only runs a low 9....

 

im sure you have way more track time but i was never able to find a gear for my 120hp cub that would keep it loaded. it would labor over 100ft before the 1/4 with a 19/38 gearing and 21.5 tires.

 

we have obviously had 2 different experiences, but mine was lack of load allowing for overrev. it could be partly to only having a 5 speed trans.
