camatv Posted November 4, 2011 Report Share Posted November 4, 2011 has anyone called kevin gigot about this?? his "kit" is reasonable. as far as ultra reliable with tune hmm. as the motor wears the tune needs adjusted carbs actually compensate for this some.. efi dosent.. i think a single tb is a good idear.. as far as the rest it should cost as much a set of carbs. i dont really know anyone who will lay out 1500 for injection on a ban unless they are going to be building a turbo.. oh and 34pj's blow and thank god they are discontinued.. in my opinion!! you would need a MAF sensor and a large range O2 sensor to really make it work right.. OF course i'm a complete ding dong but the OEM stuff i used to work on was lightyears ahead of the bullshit i see on the atv's.. Quote Link to comment Share on other sites More sharing options...
BUILDER Posted November 4, 2011 Report Share Posted November 4, 2011 This is awesome 4 pages of people talking about Zilla failing at putting EFI on a bike when 358banshee has a good running banshee that he has pretty much got the EFI dialed in on. If anyone has a clue of what this would cost it would be him and he is telling you that your price range is not resonable. Let us know how it goes getting your local dealership to donate parts to a EFI project????? Quote Link to comment Share on other sites More sharing options...
wesw Posted November 4, 2011 Report Share Posted November 4, 2011 . Let us know how it goes getting your local dealership to donate parts to a EFI project????? Hours working the glory hole my guess Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted November 4, 2011 Author Report Share Posted November 4, 2011 Haha. No dealership is going to donate to some individual building an EFI system. Quote Link to comment Share on other sites More sharing options...
camatv Posted November 4, 2011 Report Share Posted November 4, 2011 sweet! hmm an in~tank pump like the 700 uses would be nice.. i perosonally hate the big clunky fuel pumps hanging out all over the place.. if you can plastic weld or build a alluminum banshee tank and just make the flange to accept the 700 pump assembly?

andrew3160 Posted November 4, 2011 Report Share Posted November 4, 2011 I am curious to see how this turns out. I have a 2 stroke Kawasaki Stand up jet ski and I know there are kits on the market to convert them to EFI. I know the motors are set up different, but I have seen it done on both a reed inducted 550 two stroke and a piston port 550 two stroke. Here is a picture of the kit for sale on another forum made by Injected Research Specialists bought from west coast for a 550 reed motor. I can post up contents if any is curious. I also know that JSR Performance has been successful in putting an EFI kit on a Banshee. I don't know a lot about Fuel Injection for 2 strokes but I am sure it would be a fun project.

THE358BANSH Posted November 8, 2011 Report Share Posted November 8, 2011 i plan on using a fuel pump and injectors from a yfz450r. With that large of an injector, you will be using only a fraction of the duty cycle available and probably wont even get into the sweet spot of responsiveness. We talked about sizing injectors correctly, but if you are not going to follow the minimal rules to EFI you will set yourself up for disappointment. Second, have you seen the fuel pumps out of the new YFZ? They are down right donkey dick huge! That means there is going to be some major space renovation to fit one, and most people won't like that. There are more compact in tank pumps on the market now that would work much better. That was one of the things I was planning on doing this winter to my stuff, aluminum tank with an integral pump.

THE358BANSH Posted November 8, 2011 Report Share Posted November 8, 2011 also, where are getting the info about the size? i cant find it. The internet is not the only form of information. I have an Asnu brand injector flow bench and have tested most of the 450 injectors for pattern and flow to see if they were acceptable in other applications. As for keeping it Yamaha, don't kill yourself trying. They are not paying you to represent them, so do whatever you need to get the job done even if it includes using different branded parts.

THE358BANSH Posted November 8, 2011 Report Share Posted November 8, 2011 That takes the fun out of designing your own kit! The six P's pertain to a project of this magnitude... Proper Planning Prevents Piss Poor Performance "Designing" a kit is going through the proper calculations and doing the research to prepare yourself for what is to come. Throwing a bunch of parts at something without a good game plan of how the necessities need to function is a good way to end up with a cobbled mess that functions like ass. Zilla, I won't provide a list for you. The links I provided a few weeks ago will tell you everything there is to know about EFI from design, to calculations, and all the way to installation of the planned components. You have everything at your finger tips to be well informed and successful, you just need to be a sponge and soak it up! Evan Quote Link to comment Share on other sites More sharing options...

Starwriter Posted November 8, 2011 Report Share Posted November 8, 2011 If you're planning on selling it, you probably should do a patent search too. Scroll down to "objects of the invention" http://patents.justia.com/1994/RE034803.html You don't want to end up like Polaris and be $57,000,000 poorer. http://www.niroip.com/document.php?Id=57 Quote Link to comment Share on other sites More sharing options...
Judge1 Posted November 9, 2011 Report Share Posted November 9, 2011 All I know about EFI is that it is way too expensive and hard to work on. Elegant simplicity is what makes these bikes so awesome! Quote Link to comment Share on other sites More sharing options...
SmartParts Posted November 9, 2011 Report Share Posted November 9, 2011 I mentioned in the survey thread, so I guess I will post it here now. You would see better performance gains from an electronic igntion. If you are outsourcing the ECU portion of this to another company you aren't really doing anything other than assembling legos. The brains behind EFI is in the system that runs it. Quote Link to comment Share on other sites More sharing options...
