General Two Stroke Talk / Courtney Duncan WMX at Hangtown Qualifies 1st on a YZ 125
« on: May 25, 2013, 02:50:34 PM »
Maybe, it's just that it sure doesn't look that way here. Just as it sure didn't look that way when Mike Brown and Grant Langston were racing the YZF250's up the hills at Glen Helen.
There was this weird disconnect between what the announcers where saying was happening... and what you could see happening with your own 2 eyes as the bikes raced up the hill.
Of course, you did have to time them back then because in the early laps of that race, the 4 stroke could still be seen in the same shot, unlike this example.

General Two Stroke Talk / Courtney Duncan WMX at Hangtown Qualifies 1st on a YZ 125
« on: May 25, 2013, 08:39:26 AM »A bystander video just showed up:
I don't know how the undercover 4 stroke trolls among us feel, but I'm looking at the speed of the 2 different bike types going up this big hill and the 125 with pipe and reed cage looks just as fast as the factory and professional team prepped, 100% advantage handicapped, fuel injected, 250 foopers.
4 Stroke trolls might be able to make a case for this is the video was shot on a tight s curve or something "Where the slower but lighter 2 stroke has an unfair advantage"... but this wide open uphill??? Seems to me that even a totally unskilled rider could do a decent job nailing the throttle up this hill. Situations like this where the terrain isn't acutely challenging are where the power of the BIKES show through with less input from rider skill.
And I see the half sized two stroke shooting up the hill just as fast as the foopers... So I'm not convinced that they are so much faster. Oh there's also the fact that the two stroke wasn't given a head start as far as I know, and all these riders are in the same racing class, and the 125 is like 1/2 a minute out in front...
I know undercover 4 stroke trolls don't agree, and I know that those who are passionate about getting equal displacement almost come off more like 4 stroke trolls than 2 stroke fans - because of the way they constantly talk down about 2 strokes and favorably about foopers, in order to try to justify their equal displacement desires.
But I know the 4 strokes don't look any faster in this fan video even though they have advantage after advantage piled up like cow patties.

« on: May 19, 2013, 05:12:36 AM »Yes she may be "too fast" for the womens class but she is also 30 SECONDS A LAP too slow to make the guys class! So she is much better off smokin the 4-jokes in the womens class
I don't know where you're looking at those numbers.... - BUT On the Lucas Oil Motocross website:
I see a Moto 2 Fast Lap time of [2:10] from Blake Warton (Male/Pro - 250 cc ("Foo-Fifty" I hear people in the pits starting to call those 4 stroke 250's now...)
I see a Moto 2 Fast Lap time of [2:19] from Courtney Dunkin
That's a difference of 9 seconds - Blake Warton is a PROMINENT male pro - Blake Warton was on a 250 Fooper - Courtney was on a 125 Stroker - Also, Courtney kinda' looked like she was just cruising.....

Did Cedric ever get any support from KTM??? Nope, he put their 250SX bike up on the podium in Paris, and won some rounds of Euro Supercross, but because he was on the 2 Stoke model, they told Sarholtz KTM, the shop he was riding for, that they would not offer any support.

General Two Stroke Talk / Courtney Duncan WINS both motos over FI Foopers by a pretty big margin - YZ125
« on: May 18, 2013, 05:28:06 AM »
Thems was some flounderin' Foopers... The announce-a-tards didn't really know how to approach the situation. She was putting such a whooping on the poopers out there, but they knew they couldn't say anything like, "Courtney's really laying down the pace on that one two five... No one's even close!"
They kept referring to her bike only as "The Yamaha".
Funny how we used to have to hear about it 6 times every minute if the lone Fooper in the field made a pass for 10nth or something stupid... It used to be like "WHOA! would'ja look at the 4 STROKE ROOST as Yarg Smerts rockets into the top 15!!! OH MY GOD David, I can't believe the POWER of that BIG 4 STROKE as HE GRABBED A HANDFULL..... and...... wait, he.. he just lost the spot to Barry Carsten on the borrowed RM250... "
Definitely balanced reporting and promotion from the announce-a-tards.

« on: May 18, 2013, 04:33:52 AM »
Just found this write up while scanning for the results of today's race, since the network/industry coverage kind of sucked....
Courtney Duncan, riding out of New Zealand, made a big impact in the 2013 Lucas Oil Pro Motocross Women?s Triple Crown season opener, winning both Moto 1 and Moto 2, each by a commanding margin. Adding to Duncan?s remarkable performance is the fact that she pilots a Yamaha YZ125 two-stoke. In Moto 1, Team Honda?s Sayaka Kaneshiro finished second, followed by MTF?s Mackenzie Tricker in third.
Duncan got the lead early in Moto 1, followed by Kaneshiro in second and Tricker in third. KTM rider Alexah Pearson settled into fourth and was followed by Yamaha?s Jessica Patterson in fifth. Patterson started to move up the pack during the contest, making it up to third mid-race, but before the end she unexpected pulled off track with an issue, leaving her to finish 30th.
Duncan continued her charge, building a gap of over 20 seconds on Kaneshiro.
In Moto 2, Patterson returned determined to redeem herself after the disappointing result in Moto 1. She quickly moved to the head of the pack, but Duncan was close behind in second and within six minutes had passed Patterson for the lead. Once out front, Duncan again displayed her superiority over the field, creating a gap that grew to over 14 seconds by the checkers.
Patterson held on to finish second, followed by Kaneshiro in third and Honda rider T-bug Higgins in fourth. KTM rider Jacqueline Strong rounded out the top-five in Moto 2.
Duncan leaves Hangtown with the lead in overall points, eight ahead of Kaneshiro. Higgins sits third overall followed by Tricker in fourth and Strong in fifth.

"The Motocross Vault" on YouTube has been deleted owing to complaints issued by Duke Video.
This move limits access to real Motocross and Supercross, while YouTube is jam packed with farty 4 stroke races. I am not interested in 4 stroke races no matter how well hyped they are, so the racing I like to watch is missing now.

General Two Stroke Talk / Superbikes Of Supercross - cycle world. More food for 2T thought

Are you saying that you wouldn't expect a 5% gain in horsepower if you increased compression by 11.2% 
All I'm saying is that the increase in compression accounts for the increase in horsepower. With that much difference in the compression ratios in favor of the fuel injected example of nearly equal displacement, it doesn't appear that there was much gain, if any, resulting from the fuel injection. It appears to have resulted, in fact, from other differences in design.
The other demonstrative precedent is the fact that 4 Foopties haven't gained any horsepower as a result of fuel pumps, fuel pressure, and the resultant, frequent failures associated therewith...

"Here is some food for thought:
-1970 Chevy Vega, carbed 2.3L making 90HP.
With a compression ratio of 8.0:1 and 2 valves per cylinder
-1990 Chevy Corsica, injected 2.2L making ***120HP???*** ***WRONG ANSWER*** It actually makes only 95 Horsepower - BECAUSE of a substantial compression ratio increase over the aforementioned engine, to 9.0:1 (That's an 11% increase in compression) also 2 valves per cylinder
So... the Vega had 1/22 more displacement and 11% less compression, and it produced 90 Horsepower..... And the Corsica with Fuel Injection, 1/22 lesser displacement, and 11.2% higher compression produced 95 horsepower???
That's really not impressive... After all, any of our bikes could surely produce 5% more horsepower if granted a 11.2% increase in compression.

The carburetor on the typical two stroke motorcycle engine is extremely unlikely to fail, because it does it's complex job with very few moving parts, no stupid fuel pump, and with the fuel and the air both at atmospheric pressure.
Apart from the fuel and air, notable moving parts are the float assembly and valve, the slide with it's attached needle, and the spring between the top of the slide and the cap which returns the slide and needle to the closed position along with, or in the absence of gravity, when the throttle is closed. Those are the full time workers, the choke slide is a part timer who hardly has to do anything.
Because of that robust simplicity, carburetor failures are so unlikely that it's almost like worrying that you won't get to go riding because of a catastrophic number plate failure... In all the time I've had bikes and hung with groups of people who rode, I have never known "Carburetor failure" to stop a ride from taking place or end one suddenly with no way home. Both of those scenarios seem pretty remote, judging from my own experience and that of everyone I know.
But don't take my word for it, do a fun study of your own! - Go to "The Motocross Vault" on YouTube and dig up ALL of the great 2 Stroke motocross and supercross races you can find and watch them all. - You'll be waiting a REALLY long time (Forever) before you're watching a race and you see someone grind to a halt due to "Carburetor Failure". You'll probably be waiting even longer than that before you're watching a 2 Stroke race at the drop of the gate, and one guy's bike just sits there, engine suddenly dead due to "Carburetor Failure", while he kicks and kicks.
To see those kind of funny failures happen with some regularity, you have to fast forward to more recent Foopercross and Mowercross, and the handicapped, crutch bristling barges of today's weak scene. The complicated, stupid fuel injection systems that were supposed to be a bandaid and a shot of caffeine for the lumpy and flawed induction and power curve of the Fooper, fail like balloons in a preschool. I don't even watch modern pro MX and SX that much because of how boring it is, but I've seen Justin Barcia, Ryan Dungey, John Dowd and Vince Friese and many more pro riders each end up stranded on the starting line (Barcia more than once!) because their ultra-dependable Rube Goldberg fuel system crapped out suddenly..... And that was after a whole squad of professional wrenches had hunched over the junk for hours and days preparing! Where would that leave someone who doesn't have a squad of professional wrenches?
Oh... I can't WAIT for that trouble-free fuel injection!
His bike wasn't going anywhere.... And speaking of bikes that don't seem to be going anywhere...
I'm not trying to muckrake, but there's a lot of BS that people spew about all the problems "You're going to have", with a carbureted bike and they are almost always fairytales or miss labeled, unrelated problems. Then you get the same people singing hymns about fuel injection and making false comparisons that use Foopers or some "SS A.A.R.P." center console fishing boat engine as examples.
When Foopers with fuel injection were first introduced, the hype was "You'll never have to worry about anything fuel mixture related ever again, because the system with adjust to anything"
BUT, then that turned out not to be true, because the bikes needed to be adjusted to deal with heavy load conditions like deep sand and some other things like that, usually to richen the mixture and keep the operating temps from spiking so high that the pieces of crap would eat themselves alive .... SO they started including alternate couplers and other poo, so that those Fuel Injected Foopertroopers could "Re Jet" their bikes for those special conditions. ...So as it turned out, they still have to tune and "Jet" their Foopers occasionally, and they get a reduction in reliability and serviceability, an increase in weight, and an increase in cost in the not-a-bargain to go along with it.
And the hype that 4 stroke trolls like to harp on about how you CONSTANTLY have to keep trying to jet your 2 stroke.... Well, that's a load a manure too.
On a 2 stroke streetbike, do you really think you'd have to start by jetting your bike in Seaside Heights, then stop in Easton, PA and re jet because you gained some elevation, then stop again in Hazleton, PA to re-jet again??? No, you wouldn't... You'd be too busy just riding along and enjoying yourself.

Not too surprising... It's usually wise to assume that the last place bike is a 4 stroke.
The compiler of the list is relying on the "Foopers Last" rule.

Personally, ever since Fonda went all 4 stroke I don't care about them at all. I do enjoy watching them fail though, that's my favorite!
I'm hoping to see them still stuck with like 8 CRF Onefarties at Hanover Power Sports this weekend. Seeing those 2008 models still sitting there makes me laugh harder every time.
Nothing's more fun than a 100% fooper company falling on it's face!

General Two Stroke Talk / Is it me or have we slowed down a bit??
« on: February 14, 2013, 03:04:55 AM »
If like me, you're in the habit of looking at this forum first for news and fresh activity with regard to TwoStrokeMotocross.com, then things could be perceived to have slowed down. BUT, we have to keep in mind that TwoStrokeMotocross.com's web traffic and "Real time" web activity are more spread out now, with much happening on Facebook and Twitter and things like that.
There's TONS of activity in the TwoStrokeMotocross.com family of sites and pages, but there are now MORE sites and pages. Because of that, the stream of new posts and interactions in any one place is bound to slow a bit.
In the past, we used this board as our main "Real Time" exchange, and looked at the main page for the articles. Then we'd usually discuss those articles from the main page here, so traffic was very deep. Now we've decentralized that stream a bit, because we also interact on a real time basis through some of TSM's other channels.
It's not necessarily a bad thing, the Facebook and Twitter stuff is probably good for the site demographically. But at the same time, we have to expect it to weaken the pulse of this forum a little bit.

General Two Stroke Talk / mxa used 125 build and 144 shootout
« on: October 26, 2012, 02:23:08 PM »
Yeah, that's true. And DEFINITELY at the pro level, where the people have the talent to ride a 2 stroke and make the most of all it's advantages. That's probably the reason why as long as there were two strokes in the pro races, they either won or very nearly won.
At the amateur levels, many of the riders are less skilled, so the Foo-Fifty four stroke fooper with it's boring, uneventful power and sleightly mushy acceleration caters to their needs perfectly. They don't have to worry about the intimidating suddeness and immediacy of the 2 stoke power, and they can poo around all day.
A four stroke does help the least skilled riders to poop successfully over some bumps where they might otherwise drop it, due to their lack of ability. The fumpers have definitely provided a learning platform for the lesser riders, and for wives and girlfriends who want to be able to just putt around without the bike constantly urging them forward into territory they might not be able to handle.
The four stroke's flat, boring power characteristics do have their place and they pair well with the girthsome and sluggish handling to produce a less intimidating package for beginners.
But people don't really care about that so that's why so many of them are piling up unsold at dealerships everywhere.
The lack of enthusiasm for the foopers in general might have something to do with people being smarter than the industry thought they'd be. Even though all the factories forced their "Visible Personalities" to switch off the real bikes and onto the foopers, people realize that the pro's will ride anything for a paycheck, and even say nice things about it for the money...
But, the fact that the two strokes dominated until the paychecks forced the last people off them reveals the reason why they had to be eliminated from pro racing completely by the industry via the paychecks.
They couldn't make the foopers look very good while they got gored by motorcycles half their size all the time.
