This is the only cheap one I know that can be had with a throttle body that bolts on (200cc kit). https://www.aliexpress.com/item/micr...31a02e0eShwOq6

This is very true. But living in the south we don't get much cold weather and with the carb tuned properly I rarely have to use the choke.

I think what turns most people off is that it is almost half the cost of the bike just to get the kit.

i live up north ,but no efi for my hawk ,i would do a oil cooler first ,,just had way to many
bikes run fine with a carb,an i dont ride below 50 myself ,or rain ,or winds over 30 ,those 3 things i just think takes away from the joy of rideing a bike on a 80 degree day, dont mind putting on gear 50 to 60 f ,personal thing i guess,plus the new hawk will have efi i guess you could say i am not a hard core rider anymore ,now that i have a few camaros to drive too,things are subject to change allways

That doesn't mean EFI isn't lacking several advantages. The biggest advantage being consistency. No matter what your elevation, the air temp, humidity, etc, EFI will alway be in the most optimum state of tune. Carbs may work with little adjustment, but to run in an ideal state of tune all the time requires regular jetting adjustments. Most people don't want to go through that headache, which is why EFI as a whole will get more consistent fuel economy. I could ramble on for hours, but to make a blunt point. EFI does offer advantages over carburetors in terms of functionality. One that hasn't been mentioned so far is the ignition controlled by the ECU, giving you much greater tuning ability than just fuel alone. The real drawback for those of us with our currently carbureted bikes is the cost and/or the unknown factors. You spend $600 for an Ecotrons kit, and it will be good quality and can self tune, run multiple fuel maps, etc. Or spend $270, and hope the parts work properly, the software isn't terrible, and have to spend hours and hours tuning it yourself. If I were going to upgrade to EFI, I would also consider a stator upgrade to handle the extra load on the electrical system. Something nobody has brought up yet.

The biggest advantage with either one of these EFI systems is you will have the capability to change the timing table which means to can increase HP. The same can be done with the carb with a programable CDI. The only issue I had found was the programable CDI only comes in a DC version which means you would have to convert everything over from AC to DC. Don't know if these kits are AC or DC. If DC then you will still have to make that conversion too.

At first blush I thought that statement was ridiculous, but then I realized I was wrong. Cars and pick-ups from the '80's on have had some form of fuel injection in order to meet pollution laws. So, yeah, most anyone younger than 50 may very well not to have ever used a choke or 'primed' an engine to start it in cold weather. I can see myself spending $600 so I won't have to choke it. Yeah, like, I really can ...ARH

You purposely set your VE table to be on the rich side throughout, then build an afr targets table, and with wideband o2 autotune will nail it in safely right where you wanted it. slowly leaning it toward your targets, as you drive. Iv'e used it on 2 turbocharged lampredi twincam 4 cylinder engines and have been very happy with the results. The key is having a rock solid wideband o2 sensor.. wich can be had very cheaply these days. On the second car I used a very good and inexpensive controller from https://www.14point7.com/pages/products. I think I paid less than $50 and the unit works better than the $300 plx device I used on the first car. I have learned an awfull lot about FI building and implementing 2 megasquirt units. Now I swear that one of the chinese units I looked into was actually using the megatune software. |
