Found it I think.I find all his videos are well done,and most don't have a gay sound track to ruin it-just the sound of the bike.Here you go.....

#1  Part three of the long term Maico test appears to be missing

#2  It appears someone stole the "Two stroke motocross.com"  arched front fender stickers from the store

C'mon man,patience isn't my thing

I believe you're right on the ATK?Cannondale thing MS,but as for the magazines,it was either Dirt Bike or Dirt Rider who officially had it on the cover of their mag as "bike of the year" before they'd even ridden it.Once they did,and took all the heat for what it turned it out to be,they hauled their heads out of their a$$es and tried to say they named it bike of the year for the innovative thinking and technology it represented that would further bike development across the board-lol.Thereafter,I never bought another of those magazines.

OK,I'll just say one thing on the AE thing.Hydrogen isn't really a clean power,it is to the end user but it has to be produced.As for electric,here in N.S.,roughly 92% of our electric comes from coal.Again,clean to the end user.

Cool technology but I'd miss the sound-maybe a hockey card in the spokes would do the trick

Another thought never really occured to me until this spring.You read about electric bikes and how long they can go on a charge and how long to recharge and all that but it's a little more than that.Granted,this example isn't of the highest technology but by nature,would be much the same.Anyhoo,one of my daughters friends has an electric dirt bike(the name escapes me at the moment but maybe I can find a pic)This spring she came over to do some riding.Her bike is supposed to last an hour on charge and recharge in forty minutes.When compared to my daughters jr50,the power is nowhere close though top speed is similar-initially at least.Starting from a stop on a hill required foot pushing assistance even when fully charged.After about ten minutes,the power drop was noticeable and by about 40 min,it would hardly move-and took about 1.5 hrs to recharge(they took turns on the JR in the meantime)Just like a battery powered flashlight or radio,I'm sure a full sized bike would lose power like this as well.It's one thing to say it has all the power of an IC engine-but for how long?Something to think about that I never see mentioned anyway.

The FCR can be made to work well,it just takes a little fiddling.On one trip I got 92km out of mine with about 2l left in the tank(9.5l tank)On mine,I put a lineweaver jet kit in it,which eliminated the accel pump-or was supposed to.It worked well and increased the mileage tremendously .95% of the time,it was perfect but when you needed to give it a hard crack,it would bog.I ended up putting the pump rod back in but then at low speeds through the rough stuff when you were sort of blipping the throttle,it would load up.I ended up taking the carb off,filling the bowl and activating the throttle.The gas that shot out hit the wall past my workbench about 6ft away-and kept doing it for about 3 seconds.It took just a little throttle to do this so you can see why it was loading up.Interestingly,there was a round boss on the carb body behind the pump cam(almost like it was made for this) so I drilled and tapped it and put in a spring loaded screw and adjusted it to limit the cam travel so I had about a .5-.75 sec pump squirt(as low as I could get it before it wouldn't activate at all)This was the cure in the end.
As for fuel injection,I like it.I've been an auto mechanic for the last 20+ years and well remember standing in a snow bank adjusting choke thermostat tension,choke pull,fast idle etc while the fan blew -20' air over you-brrrr.I don't miss that at all.Mapping issues aside,I think the biggest issue with the bike systems are their simplicity.Most are an open loop system and those that aren't don't have much more than a cts and o2 sensor.It's hard to get an FI system to operate in all situations with such limited inputs.I've never seen it mentioned but what bothers me more about the bike systems is the lack of fuel capacity.Whether just due to the space the pump takes up or tank design or both I don't know but 6.5 l is a pretty skimpy capacity imo.It would be ok for MX but scrambles or off road it would be a curse.

The strawberry smelling stuff is Ipone.It's good oil and smells good too(and made by Motul).I use Motul 800 and have no issues-but it lacks the strawberry smell.

I've ridden a 470 Berg. I loved everything about that bike...except the 4T engine. It had all the characteristics of every other 4T, such as stalling, bogging, nasty hotstarts and if compared to an equal displacement 2T, lacked bottom end.

I stand by my OP.

If you were riding a 470 that would make it what,about a 2000 model or so?They had some issues-still running the sem ignitions and dellorto carbs if I remember correctly.05 and up are a good machine-the latest generation efi models are better yet.Mine was an 05 and had some carb issues as delivered due to emissions regs in some markets but once I finished sorting it out it ran flawless.No stall,bog,hesitation or anything else.1-2 kicks when cold,one when hot and I never had to touch the hot start once the carb was dialed in.As for bottom end,it didn't have the crack of a 2t but within about 30ft would leave the 250 2t's I rode with(including the one I have now)for dead.Having said that,the gyro effect of the big engine made it difficult to point and shoot in tight woods and though light for a 4t,it was still heavy by 2t standards.Add to that the fact the it would overheat in a tight,snotty race much more readily than a 2t made it annoying at times.It was super stable though,handled good and had enough torque to allow you to dig trenches or shift up a couple gears through the crappy stuff to avoid wheelspin.
Generally speaking,I prefer two strokes but I don't look at things with blinders on so I can see 4t's have advantages in some ways.I also don't believe in judging a machine based on the riders lack of mechanical knowledge or inability to tune it correctly.I've seen some pretty crappy running 2t's as well but I never blamed the inherent design of the engine for it.

General Two Stroke Talk / Re: 125 vs 144

« on: December 14, 2009, 04:42:20 PM »

If I remember correctly,the KTM 144 is bored and stroked both.If the bike you're looking  has only been bored you may find it lacking on the top end.A 125 with a 250 like powerband wouldn't be my choice but it depends on your riding style I suppose.

Hey,my second or third post and I'm disagreeing with someone already-sweet
Previous to the YZ I had a 550 Husaberg and it was an excellent machine-in many ways,superior to any two stroke I've ever had-and in many ways,not.The search for the perfect bike has left me with one conclusion-there is none.I always thought if I had a switch on the bars of the Berg that would transform it to my old 125SX and back again depending on the situation,I'd be in happy land,failing that,I find a 250 2t is a good compromise.

Thanks John.I'll keep an eye out.Do you know if there will be a Canadian importer?I'm a sucker for something different-probably why previous to the YZ I had a Husaberg.On the other hand,If I had the $$ right now I'd likely have a new TM sitting in the basement.Maybe next year.....

Hi guys,cool site.I had to register when I saw this thread.My problem with Maico has always been that every year for probably the last ten I've heard "Maico's back!" and each year it seems nothing happens-until the same headline next year.Are they actually producing bikes presently with whoever owns them now or are they just throwing out a few one-offs for the new year.
