efi

Figured I'd toss this here and see if any of the smart fellers here have any ideas on what's going on. It's a 2012 Yamaha Zuma 125. Fuel injected single cylinder scooter. Been modified with a 155cc big bore kit, cam, and Bazzaz fuel tuner with wideband O2 self-tune module. After all the mods...

From the drawing board to reality. The plan is to make something that has the same dimensions as the stock carbs to be able to use mounting brackets, butterfly’s and linkage, along with a custom ram-air kit. The design was done with solidworks and modeled around components that are easily...

I have been talking with my buddy who has successfully built a few EFI systems for sleds and the like. He is an electrical genius and can build all the computer and electrical interfaces we need supposedly. I might give this a go over the winter but am trying to do a little more research on...

Wath do have to say about that kit:ummm: House of trouble:bang head: or EFI no more carb issue:worthy: :ummm: http://www.ebay.ca/itm/140806032086?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2648#ht_500wt_1289

It is time to let my stenten 45mm EFI go becouse I am building turbo for my vmax. Comes with all you need to get it running, can be sold with power commander witch makes tuning very easy + possibility to add extras like quickshifter, auto tuner, display etc etc. make me an offer and we will...

Hi guys, I am wanting to go down the efi route but still in the dark ages with it all at the minute, I will greatly appreciate all the help i can get So 1st of all the bike is vmax '92 fullpower! I'm not aiming to make my baby stupidly more powerful, just more efficient, more responsive...

Im having trouble AGAIN ,:bang head: and Im wondering if it might be in the charging system and not the EFI this time:ummm:.so for you few guys with the WB system, how would/could a weak/bad charging system affect the funtion of the EFI.. runs great when Im on it hard :biglaugh:,but seems to...

Hi all, I'm doing some orientation about engine-tuning and some user-experience is very appreciated. My starting point: I want to get extra RWHP on continuous basis (so not NOS dependant) options are: bigbore / flatslides / EFI / jetkits at the end I want to be able to integrate a...

does anyone had any live comparison of this in the same engine??? i am sure many of us would like to know what works best.

Those of you running EFI, have any of you gotten it working well off the bat? Or does it always taken tons of tuning down the road? Have an opportunity, but so far i've only heard headaches.

Gonna start working up a turbo kit... anybody interested? Just trying to get some numbers for the amount of detail parts I should machine. The one setup will be configured to run a blow-thru with mechanical or electronic fuel injection or draw-thru with a Mikuni HSR. It will also have provisions...

Well guys, just got a notice about F.A.S.T.'s new EZ EFI system. It's designed for cars but I see no reason why it can't work with a custom intake (or adapters) for the Vmax. I haven't checked to see what my discount level is for pricing either. The nice thing is it's a "learning" system so...

Hey guys, I need help,and its not often Ill admitt it , but here goes. last year i bought a 89 max from a friend that had the bike 17 ,yes 17 years. many mods over the years . the last mod he did frustrated him so much he gave up on the max, it was wildbros EFI, he thought that he would get it...

Hi All, A while back Mark (birdoprey) mentioned coil choices using the Haltech ECU. Popular coil's used with the unit are the GM LS1 and LS2's. He also mentioned that LS2's have their own heat sink and we're real flame throwers. Something I need for the race bike running methanol. Sooo I...

Ok... time to get a little technical! The only concern I have with the 600 TB's is the fuel flow with the injectors. I did some digging and found these numbers based on the different bodies. GSXR TB specs: 750 & 1000 from 2000-2003 750 & 1000 are essentially the same 270cc/m...

The GSXR throttle bodies have arrived, here are some pics. The sets should be a 1000, 750 and 600. The two larger sets are dimensionally the same. The good news is the center distances are the same, be it a 600 or 1000. That will make it easy to respace the bodies. The same details will work on...

This is the ECU we're thinking of using for full motor management. If your interested... read up! http://www.haltech.com/index.php?option=com_content&view=article&id=21&Itemid=18 Anybody have any experience with it? It's loaded with good stuff There's even an on board dash available...

To get an idea of how many VMAX owners are actually interested in the EFI conversion and to air questions about the setup. I thought it would be a good idea to start this thread. Anybody can post a question and along with the question we might want to poll that question. That way we could get a...

I'm working at making up a set of manifold's to adapt sport bike throttle bodies. This a big project and we'll need lots of help from everyone to make it happen. The goal is to come up with an affordable EFI setup... hopefully a complete engine management system for the MAX. Any fiberglass guys...

Well, since going to the "dark side" for sucking in fuel, I thought there should be a sub forum for it for those that have thought about going to EFI. :biglaugh:
