Do efi,s really do that much for the scooters 300cc and under and if so whats the advantages? ,and is it really worth the expence and work making the changes?? .
because abouit 2 yrs ago we did this to a 360 mc ,
and except for it being slightly more fuel afficent thats was all nothing changed at all the cycle ran just as well with out as it did with it, and yes we did set it up right perbatum, and the kz was only 8 mo old with 800 miles on it,
as i said what we gained wasnt worth the expence time and truble putting it on and havind it, plus was really more expensive to fix or replace if it should go bad a lot more than just rebuilding a carb, so whats up guys is it really worth doing to a scooter ??

to me yes i do not like the carbs that come on these scooters the only thing that would be better about the system if it was able to use less amps so you would not need to upgrade the charging system i have been running mine for a few months now and every time i want to ride i just hop on and go the throttle responce is great and feul cost is great i have no holds about getting on and going for along ride now as with the carb i was not as pleased with the preformance and would not want to go places that i can now

ok what i know about transformers is when you increase the amps the voltage drops and vise versa

ok what i know about transformers is when you increase the amps the voltage drops and vise versa when you use higher voltage the amperage drops down , when you lower the voltage the amperage goes up . A larger wire will have less resistance and will hold higher amperage . The idea high voltage for long runs using smaller wire . John |

ok sorry for some misinfo the bike we put the amp multipler on had a large generator with a vary high out put we had to lower the voltage to get the efi to work right thus the step down trans former to lower the voltage and raise the AMPS, sorry for the wrong info
it seems your going have to redo your charging system after all if the efi is drawing a lot of amps , or raise your idel speed other wise the higer amps may cause the battery to go bad if the charging system cant keep up with it
again vary sorry about the wrong info

On the scooter I converted to 11poll stator , I pushed the idle up to 2000 and it stays above 13vdc at idle with all the lights on .

did because i do not like the carbs that come on mine and it will give a better air feul ratio though out the throttle curve with the EFI system on i have better throttle responce and no more flat spots and bogging

once again
i must say this...
BUT AS I DO I AM TYPING WITH ONE HAND

i must be a lucky scooter
i have NO probs with throttle response, no bogs etc etc
only prob i've had in 7100+ miles 2.3 years
is the magneto died

I understand the theoretical advantages of EFI but until someone builds an economical scooter with the system installed count me out. The Honda Reflex, Big Ruckus and Helix all came with carburetors and seemed to last for hundreds of thousands of miles without needing their carbs fiddled with. I have close to two hundred thousand miles of two wheeling with carbs and I can count on one finger the number of times I opened up and cleaned a carb. That one was left with stale gas in it for somewhere over 5 years without running and the carb had petrified deposits in it. Despite being abused and thirty one years old that diaphragm carb works just fine now. Of course it's a Mikuni and just a tad better than your common Chinese carb.
