• 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 The previous version was outdated and no longer supported.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!

How to: EFI to carb

Well I figured I would make this thread so others don't have to go threw the madness I did. First off I did this on my smr where I needed lights. It is much simpler without lights. Here is a list of parts needed.
1. 07 or older wiring harness, cdi, volt reg, kill switch, stator flywheel and cover
2. 07 or older carb or a carb from a post 08 carbed bike. Tc or txc.
3. 08 or newer carbed bike fuel tank
4. 08 or newer carbed bike air box boot and intake boot.
5. An EFI flywheel puller yes they are different
6. 07 or older start stop switch, or you can use the mx style but will need two.

the efi coil will not work. the reason you will need a cover is the efi stator uses 3 bolts to mount the stator to the cover. the carbed bikes use 2. you can use a stator/flywheel/cover from any year carbed bike, but i used a 07 because i wasnt sure if the newer carbed bikes stator had a different connector. also you dont need to buy a another tank. you can leave the fuel pump assembly in there and drill the hole for the petcock. if you look on the bottom of the tank there is a mark where it goes from the mold. personally i got another tank for simplicity reasons and the efi tank and pump assembly will easily pay for another tank.

Because the EFI sucks, my 06 510 smr ran PERFECT! And there is good reason the 450 and 530 smrr cones carbed. Carbed gets better mpg, runs smoother, less shit to break, I don't need a laptop and dyno to tune it,
 
The remaining two parts come in Friday. Waiting on a pre 08 start stop switch. They changed the connector in 08. It now plugs in behind the headlight. The older style plugs in by the coil via two bullet connectors. Also waiting on a stator cover. The EFI stator attaches to the cover via 3 bolts instead of the 2 bolts on non EFI Stators. Also the threads on the flywheel are different. The crank is the same but they changed the OD where the puller mounts. It is slightly larger. Almost done!!
 
Why would I need a dyno or laptop with the wideband?? All it does is show you your current A/F. So if it's lean or rich at a certain throttle position I can adjust accordingly.
 
Sense of humour ! Ironic you dont want EFI , Laptops , Dynos etc....

But want a "digital assistant" to help set up the carb ****************************************

Racers have used a wide band set up for years to dial in
their carbs
In reality if you don't have a wide band O2 set up for your
EFI to set your co1 co2 co3 you are just guessing

Pinittowinit keep up the good work you go BIG DOG
put a power now and a power now plus and a adjustable
leak jet in that 41 fcr and you will blast.

check out this little gismo we use to set up some of the bikes
we work on it is A on bike dyno and the LC-1 teoughter
 
Thanks for the video. Not to tooth own horn but I'm a great carb tuner. But Like you said without a wideband your guessing. Every litte bit helps with performance and fuel economy. Lije the video shows you cam tune close by ear but see how much the A/f changes without a change in the engine tuning. I'll post a video on her first start Tuesday. Then I will post a video with the wideband and let's see how close I am by my tuning abilitys.
 
Depends on where you get your parts. If you bought all new parts.,, hell I font even want to think about that. I got most of my parts hooked up, or traded, or given to me. And I'm in this for the cost of a PCv and a auto tune
