Ideas on EFI unit. Drawing board

well i was looking for EFI units that may work for our bikes.

http://www.horsepowerinc.net/index.htm

those are made for harleys, but i think i could convert it. looking at the dyno charts, i am rather impressed. It gained 15 hp and 5 lbs of torque, and also flattened the power curves. i think that would be great on our bikes. I figure b/c of our faster reving engines, that an additional 4-7 lbs of torque would be fully feasable, and maybe an additional 15 hp b/c of the higher revs then the harley. (keep in mind those harleys are already efi units)

The thing that i would love, is no longer having to deal with choke, idle adjustment, syncing, and would boost throttle response big time (i think if done jsut right, maybe might crack a wheelie, but that is not my game plan). The only draw back is that i will need to figure out the conversion from our 2 carbs to the right size throttle body. Also another draw back is electrical consumption. there will be the EFI unit, and a new fuel pump to juice. I hope frankenstator can handle it. I think if i run shy, that i can change the tail light and head light. if i need more then that, i will have to redo the flywheel with stronger magnets.

still on the drawing board, but seems like a nice project.

I think i just found my EFI unit. What is even better is that there is an add on that will adjust the timing of the spark too.... down side is that it is for a single coil distrbutor set up. maybe i can rig something up....
I guess i can use a twin throttle body set up and then i will be able to run a MPFI set up vs a TBI set up. that should boost hp nicely, and i can also tune each cyl separately. looks like conversion will cost around the 500-700 mark. Very nice for EFI considering that it is normally in the 1-3 thousand mark.

Very interesting Hizzo !
There was a guy on a KLX board I belong to that was going to try putting a EFI on his dirtbike. I haven't heard much about it lately though.

looks like i wont have any major issues. i will try and get 2 gixxer 600 throttle bodies and make an adapter plate to bolt them up. then only major issue i see that i may run into is the pick up for the ajustable spark. i may have to do some major tinkering there... then go in and remap all fuel curves, which i think may keep me busy for a year lol....well now i know what to tell everyone to get me for x-mas. although their micro squirt looks interesting. looks about the size of our r/r and supposed to have all the same functions except for the injectors. but we dont need 20 injectors lol. i did some math. fuel pump 4 amps, injectors 1 amp a peice at 100% duty cycle (duty cycle varies with rpm), and the controller will pull prolly around the 2-3 amp range.
7-8 amps... not too bad. that is about 84 watts

humm very interesting.... you know what size those would fit perfect on? Those seem like they would fit onto a hella style HID ballast. how many do you got? how much you want for them? btw thanks for the find!

So the "hizzo experimental vulcan project"? lol i like that name. I need a name for my bike, wasnt the liquid robot from terminator called the t2000?

I wonder if we can make a total upgrade kit for the bike. It would include an efi total conversion, frankenstator, and the BFB (big freaking battery) upgrade. Maybe we can include the 6th gear if someone can figure that out. right now all mental resources are tapped looking into the efi conversion, and road testing the frankenstator.

instead of a sixth gear (yes it would be great) but what if the 5th gear was changed instead...would probably have to wind out 4th a little more to be able to shift somewhat smooth but it may be an option to look into

yes, granted your idea is always an option. a machine shop would have no problems cutting new gears for the wider 4&5th, which btw i cant even go 35 in 5th in my jeep b/c of not enough torque which means our gears are too tight. I just want to see if its pheasable to throw in another shift system lets say from a vulcan 500 b/c that would be cheaper. go to a junk yard, and get the tranny, pull the gear spindles and install. vs a machine shop i would have to pay for new gears which i havent priced yet, but may cost a pretty penny. also i am very shabby on the gear ratios, so i will need someone to do all the math and so on.

anyway personally once i get the efi system installed, the torque curve will be nearly flat, which i would love a tight first gear, a medium second, slightly wider 3rd and wide as hell 4 and 5th. i would love to see the bike at 3k rmps at 70 mph (real world) in 5th gear. and with a new efi map, that would be no problem cause that flat spot in the dyno would be gone (i think it is caused by carb jetting). so if i had the money would i redo the whole tranny, you bet!!
