EFI Gurus needed. dragbike efi swap

[ArttuH]

Some good thoughts. I doubt EFI would dominate the market if it was not for the push to lower emissions.

OP is talking about a drag bike. I assumed that is was this discussion is about. It would seem that most of these bikes are pushed to the line, pushed to the trailer and held wide open from start to the end of the track. Warmup I guess is the burnout. I totally agree with you if OP is making their nitro street bike pass pass CA smog tests.

Yes, it's probably doable and in drag racing use the limitations aren't that crucial. But what's the point? Why to bother with all required workarounds and compromise performance when there are more suitable ECU units available?

And if WOT performance is the only important factor then there isn't much point to switch form carbs to EFI.

One reason to change to FI is the new bikes come with it. No reason to take it off. We are all aware that with the stock ECMs we get more than a fuel system in that box. I think the days of having all those separate controllers is nearing it's end.

For the 30 year old bikes like mine, you are right, it does not make any sense. That is unless you are a GS freak like most of us on this site! That is why I was suggesting to the OP to switch to a newer power plant. Parts are available and you can make the power levels they were talking about a lot cheaper.

as homer says, DOUGH!

:idea:

yes definately good points with this. will save the efi for a future project, got quite a few going right now so this will continue with boring the carbs and tuning the bike with them.

Does anyone know the conversion chart for mikuni jets to fuel flow in wieght? I need to know so I know a jetting guide for alky if i choose to run methanol in my carbs. I can just put the ole lump back in and play with the gas jetting at the local drag track for a while.
