• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

Excellent results from testing settings on the EFI settings...

On my 2010 TXC250 I went from 100 to 96 on the low setting on the EFI and gained better running and great mileage. Amazing the difference it made. I am getting 32-34 MPG now and I think there is more to be had. I'm stoked by these findings. More to come.

Glad to hear it. It would be nice to know we can reliably get 60 miles on the stock tank.

I am curious as to what made the difference. The efi settings, the bike being broke in or both. Isn't your bike just about at the optimal break in point ?
 
It would be nice if you had a gas analyzer to read the co2 % then you would know what your adjustments are really doing.
 
Went 4% leaner on the bottom setting. As you are in the bottom setting a lot in tight single track it made a large difference in MPG. The bike is also breaking in. You can feel the suspension getting better and the motor getting more free. I believe it still wants to be leaner, testing continues.
 
Was out playing with the EFI again tonight. I am at 90 on the low CO setting now and it seems to run even better. Also went to 104 on the mid setting and 100 on the top setting. Better mileage is sure to happen. This is EZ and fun to mess with.
 
I thought that the reason to buy these new EFI bikes was so you didn't have to stuff around with your settings , they come factory set and you leave it alone .

Why buy an EFI bike if you have to buy a $300 machine and play around with your EFI . Are you saying the engineers can't get it right and we need to keep playing with the settings .
I know the machine makes it easy to do by see where i'm coming from .

To me you take your bike in to a dealer and pay $50 for the latest EFI mapping and away you go .

A couple of things to that point. The huskys (and Berg to some extent) come real lean, throttle stop, restricted filter cage and other things to make it run super lean and pass regulations and get by red sticker and EPA stuff. Some of this is carry over from Europe. Once you remove the restrictive crap and take the lamba sensor out you have the "race map" which is a richer setting. One go around with iBeat and your right it is all good to go. I got the $300 iBeat stuff because i wanted to explore the EFI potential and have the ability to tune for pipes and such. As much as a learning experience than a necessity. It's been interesting and fun to play with. I gained better performance and better MPG and learned a lot so far. It is ridiculously EZ to recalibrate once you have it and is liberating. You can do the equivalent of the pilot, needle and main in about a minute. There is also a bunch of other useful information in there.

In the end you are right, the dealer can and will set it up and your done unless you have an issue. I wanted to learn and have the ability to try stuff so i got the setup to do that.
 
Kelly,

You are developing great info that will help all the guys with FI. I am also jealous of all the fun you are having futzing with it too. Now let's get that FI hooked up to a 2 smoke and we can all have fun.

Thanks Walt, it's interesting to mess with. Ran 92 on the low (8% leaner) and it was very good there and will get better mileage. Any less and you start to get a hesitation. Yeah, EFI on the 2 stoke would be cool for sure. the ultimate would be it it had a sniffing feature that would log as you rode then you could see exactly what was happening.

BTW i need to get back on the 125 and start playing with that, got some things brewing. ;) Want to play with your springs as well.
 
Yep, FI opens up all these cool possibilities. Great to hear that you have good stuff planned for the 125. I should have my springs on Monday and will report findings and if I can get the results I think are there.

Yep, I hope you get those guards done soon.;) I will get those at the same time as I get disc guards. Oh and we do need a better water tank.

A couple of questions:

Are you running with the insert in? If so have you cut it back?

What altitude are you?
 
Kelly

What is your temperature there. My 310 runs very hot in the summer in tight woods sections. Also the plug was white. I did adjust it to 107 114 100. I guessing this is a winter setting your are using. The 310 throttle with stock settings in tight trails was like a light switch. I just could not get it smooth.

Temp does not matter as there are temp sensors in the intake that adjust the fuel amount injected based off the temp. All the sensors are air modulation based and feed that data to corespondingly adjust the fuel. Same for altitude too. Had me thining old school jetting parameters until I read the service manual and found out these things existed.

Yep, should not matter temp or altitude.

I am currently at 93/102/104. Great performance and mileage. Obviously the 310's are a lot different in many ways so this will not translate. Might not even work well on other 2010 250F bikes, dunno. Does work excellent on mine.

throttle is still semi abrupt and does not like huge handfuls at very low RPM but once i got my head around that I just don't whack the throttle open 2 stroke style and it works great. A G2 throttle tube with a slower initial response might be the ticket. pretty happy with it as is.

Any idea of your fuel range with the new settings?

When i am not spending all day on slick clay uphills going no where I am getting about 32 MPG. Still only about 45 miles a tank. I pack a half gallon and do 55-60 mile rides no problem. Dump it in 17 mile out and don't have to pack it any more. It really has become EZ to do and am happy i can do 60 miles. I love this bike so it is very much worth it to me.
