General Two Stroke Talk / Another 2 stroke extreme enduro win.
« on: October 12, 2011, 03:55:15 PM »

In the text they say GJ rode a FE250 (4 stroke) but the pics show him on a TE250 2t

A yamaha dealer has a full page ad listing thier hot sales on new dirt bikes.

2011 YZ 125 reg 6090.00 sale 5599.00
2011 YZ 250 reg 6990.00 sale 6299.00

2011 YZF 450 reg 7499.00 sale 5499.00

They also sell 2011 KXF 450 reg 7549.00 sale 5799.00

So I guess 6 year old tech is still worth more than the current state of the art
4 joke.....

General Two Stroke Talk / my YZ250 finaly has some low end grunt.
« on: August 11, 2011, 11:21:23 AM »
Early this spring I picked up a clean 05 yz, the guy I bought it from had recepts from his local yam dealer showing the top end was rebuilt just a few weeks before.  The bike had good compression and ran strong. I had been riding an xr 400 so the yz felt like a beast. I rode it through the summer.
Raced in 5 local woods races. loved the bike but it always seemed kinda soft on the bottom. t weeks ago i got a chance to ride a buddys yz125 and it had more grunt and low end than my 250. hmmm. I figured my rings were shot as I guessed I had about 80 hours on the top end.
Pulled it apart and the piston and rings were nearly in spec, bore looked good. Then I looked at the POWER VALVES, the guy at the dealer had installed the 2 valves for the side booster ports BACKWARDS with the slot facing inside. This held them in the open position and bound them up in the cams that operate them effectively locking them in the full open position. Put the valves in the correct way and got them to operate correctly, installed the fresh Wiseco. After a proper break-in, WOW its like a whole different bike.
Check a used bike out real close.

Here Eric explains what is wrong with 4 strokes

General Two Stroke Talk / Talent trumps all else?
« on: June 27, 2011, 05:28:50 PM »
Just a hypothetical, if Reed, Dungy, and Villipoto were all racing 250 2 strokes in the 450 class would they still be sitting atop the points? Does their talent get them to the front more than the slight advantage in hp and torque? Nothing against Jeff Gibson but does he finish any better when riding a 450?
Until a top 5 level racer shows up on a 250 2 stroke will we really see what is possible.
I think that Reed on a YZ250 would still finish top 3.  That will never happen though cause the top guys will never be allowed to do that.  Too bad that we never got to see Cedric Soubeyras, he might have had the talent to scare someone.

General Two Stroke Talk / What it's gonna take.

 The only way that 2 strokes are going to make any kind of major comeback is if you, me and every dirtbike person you know
go down and buy a NEW 2 stroke bike. Now, not when the new KTM with FI comes out, or when and if the Maico finally shows up.
The root cause for the decline of the 2 stroke is that we stopped buying them.
Money rules the world and when you vote with your dollars, only then will the manufactures put development dollars into producing new, modern 2 stroke bikes. Then they will pressure the AMA to allow you to race them.
PS.  buying a used bike off craigs or ebay does not count.
Show there is an overwhelming demand and they will line up to supply that demand.
The Jap companys will not let KTM have the whole pie if they think the pie is big enough.

Last night at the local indoor race

4 strokes stall, often, and are hard to restart leaving the rider spent by the time he got it going again, everytime he was in last place.
saw this happen at least 15 times.

4 strokes are loud. You could not hear the 2 strokes over the sound of the 4 strokes. My wife hated the sound.

2 strokes we competitive in every class includiing the 450 A main. 2nd place when to a ktm 250sx

A fast kid on an 2011 150sx owned the 250 A class

Skinny kids could not pick up a spilled kx450f without help from track crew. This was notable because he tangled up with a kid on yz 250
the 2 stroke kid was just as bone skinny but was able to get the yz back on 2 wheels and lit it with one kick and finished 3rd, the 450f pilot when he finaly with help got it back on 2 wheels could not start it and the track crew dude took over and kicked about 20 times then gave up and pushed the bike off the track.

General Two Stroke Talk / easy to adjust air screw for air striker carb?
« on: January 22, 2011, 11:16:32 AM »
Does any one make a longer air screw with a knurled knob on it similar to what you see on 4 stroke carbs for the adjustable fuel screw.
this would make tuning so much easier if you didn't have to try and find the slot with a small screwdriver while wacking the throttle
especialy with 46 yo eyes.

Looking for a place localy to get VP fuel?

General Two Stroke Talk / The bottom line about the 4 stroke takeover.
« on: August 16, 2010, 04:44:09 PM »
The truth is that the 2 stroke bike = the great equalizer. in other words in a 2 stroke only world a skilled privateer has as good a chance of a podium finish as a factory rider. Think about it when was the last time you saw a privateer have a chance. 8 -10 years ago. The modern 4 stroke almost ensures that he big elite factory teams will dominate. The cost of building a maintaining a 4 stroke at the highest level is beyond reach of the privateer. Back in the 2 stroke days it wasn't that way. So by changing the rules to favor the big factory teams they have all but gauranteed that the will not get smoked by some no-name local kid when they show up to race at his home track.
