Im buying a lot bike, its an F4 that i am going to do a FI conversion on, and i have one question i havent been able to find an answer to. Do the F4s from 99/00 have in tank fuel pumps that can run the F4I fuel injection setup and if not can the tank accept a F4I fuel pump? If not, will a F4I tank fit the F4 frame? I've always been a suzuki guy so the honda side is a little new to me, any help much appreciated.

 

no, the f4 tank won't work, yes the f4i tank will bolt right up.

 

Im sure you will have to get a fuel injected motor to.. you cant just bolt FI up to a F4 motor. Hope you know that..

 

you have to use fuel inj. setup, air box, wiring harness, and tank with computer.. my buddy did this to an f4 it works if ur willing to put in the work

 

your **** up and running?

sorry for the thread jack

 

No problem, im going to ride the bike as is untill i get get the parts in. it may be an interesting undertaking but i dunno if i can part with my fuel injection lol. ty for the info on the tank, its much appreciated.

 

It'd be way better to sell it and get an F4i....that's more difficult that it sounds.

 

well, for about 1/3 the price of the f4i i can buy the f4 and do the conversion...may not be the easiest out there but i think i can do that.

 

It's not like he's building a space shuttle.

All you're basically doing is swapping out parts. Just don't forget where **** goes.

 

You don't have to, but there is a sensor that's different in the cylinder head of an F4 vs. F4i - Or I should say it's not there at all in the F4.

You can usually find pretty good package deals on ebay for complete F4i motors with wiring/ecu/throttlebodeies/radiator etc.

It would be easier/faster to buy something complete and swap it rather than buy all the injected stuff piece by piece, plus it gives you a complete F4 motor to put right back on ebay to offset some of the cost.

I helped swap everything back in 01/02 or so for a friend with a wrecked 00F4 he bought dirt cheap way back when.

You really probably are better off just buying an F4i to begin with, unless this F4 is something like a grand or less.
