TE/TC 14 TE300 made some changes to test carburation

[robertaccio]

added thunder products torque wing thingy to my carb, cut a FMF snap to about 2/3 s size and installed into my airboot- stock it was for a KTM300XCFW and did not fit.
3 holes in side cover, JD jetting standard set up for 3k-6k 72deg 38P BlU2 162 main 1.5 AS, FMF Gnarley with OEM silencer and EE S/A end cap. The R Lafferty needle was working well but man that thing was soooo much thinner than any of my 300 needles that why it works so well with the 35P, anyway I wanted to play, I may still drop this needle to the #1 slot or adjust with the red needle. still running pump premium with 40:1 maxima super m, also I installed an iridium plug BR7EIX I think is the number

Super tractor mode, we did a test loop that is full on ugly, a real 2%er trail, thing just low rpmd like a 450 4 stroka.

I also raised my float height maybe 1mm/2mm from my setting at max spec low, she was stalling on steep downhills.
Wed is Vets day we have a track get together I will do pipe swaps and silencer swaps.

just being a little careful with the snap....it expands the intake boot a little and clearance to the shock is tight. after one ride OK but I want to keep an eye on it so we don't get a chafe to the boot.

I wonder what the advantage of the snap is. Saw them on the FMF site. So it adds turbulence or creates a vortex into the carb inlet?

Turbulence is a bad thing, it should be doing the opposite.

straightens the airflow seeks to eliminate turbulence . the reason I jumped on it was due to my previous experience with the powernow devices on my 450s I used the 2 powernows- at both sides of the carburetor. it made tremendous difference in lower rpm smooth torque power, instantly noticable

 

[Huskynoobee]

Ahhh, thought they were just some wingding thing. Thanks for the clarification.

RT, at this point I think you should start a thread titled "things I haven't done to my 300".

I don't know much about these inserts? Or the fact that they could divide and or restrict airflow, by simple mathematical volume. But the velocity of airflow would increase below the divider on these devices prior to the air passing the opening slide and being in transit, pulling fuel. Turbulence would be redirected and therefore reduced. Causing a more responsive and crisper snap to the engine.

All carbs and I would say, especially 2 stroke carburetors draw 90 percent of their mass air flow from at the rim of the carburetors venturi. At the rear flange area. Since the slide is closed alot of the time. The bigger the notch on the slide or cut away, the leaner the mixture. The smaller the notch on the slide, the richer the mixture, as it resists the taking on of incoming air and putting it in transit by means of the venturi effect. That's why they have a tapered air horn inlet boot on the air box inlet to begin with. So It has an enormous area of pre-filtered air to draw upon. It still draws most of the air for the engine at the carburetors rim, regardless. That's where there is the most velocity.

The days of the old "Uni Sock filters" were a joke on our old 2 strokes back in the day (1970s). As it made the engine work harder and actually hindered performance. It caused the engine to suck air through the filter at the Venturi's flange and that air is not readily available or pre-filtered to draw upon. It's on the outside of the filters foam where it's trying to suck the hardest right near the edge. If an old sock filter was used the best thing you could do was at least space it back on a straight, or even better a tapered sleeve at least the carbs outside diameter or larger than the diameter of the carbs flange. So the supply of air was there, available and already Pre-filtered.

Haha so true!

 

[robertaccio]

just another effort to turn my 2stroke into the 3 stroke

 

[reveille]

Should of got a 200. Hehe
I'm reading of many many ktm 300 riders complaining about the new 300s and how they are down on power especially the husky. They seem to have much less compression and with the husky we have the air restrictions to address. They claim the 09, 10 versions were much stronger stock. I'm sure the new ones can be made stronger but it takes some work.

 

[robertaccio]

TE= Two Stroke Enduro = last all day in the saddle never get tired, most of us (100% me) will turn faster special test time on "soft" power delivery bike, all my efforts are to maximize the power for me, maximize does not mean maximize the HP, because with this bike thats really not to hard to do. Its a 3 stroke and thats what and how I like it.

As 2T gets smaller... the more 2T like it is.... Your 2T education is about to begin!

Compression is an easy fix. Bolt on a race head or have your squish band modified/re-machined

 

[robertaccio]

well now I am happy- JD jetting standard for 4k altitude 65 deg. Holes in side cover, FMF Gnarley with FMF turbine core 2 muffler, 40:1 Maxima super M 2 turns on the mix screw. we did a barn burner today......

 

[reveille]

40:1 huh? Is that a personal choice vs the 60:1 stated in the manual? Or is it a higher altitude compensation?

 

[Husq-a-daygo]

I agree bikes are feeling really good. I had that 3T bam bam zoom floating over terrain today. Ready for Tecate now!

 

[robertaccio]

we actually had more than orange yesterday----3 Huskys and 2 Hondas- 2x TE300, 1x FE350, 1x CR250, 1x CRF450 and a bunch of KTMs. My other 3 hundo bros (Andy and Nate) were on the gassssss big time yesterday. I was the slow guy. we will need to do special test comparos next week (hahaha) we had a sort of large group yesterday, but with little or no dust it was fun.

 

[Husq-a-daygo]

Playing catch the rabbit(Andy) was too fun.

I don't know Reveille, mine is pretty powerful! And it's stock! But I'm trying to do more enduro (woods, trail riding etc). If I was taking it out on a MX track, I'm going first off have to change the suspension to get the most out of how fast I can go. Right now I want to detune it somewhat so as to not just dig ditches if that makes any sense.
