Here is the low down from the guy who built it:
right right right!!!! this bike i built as a challange to myself and have spent some 400hrs getting the system to work,it has not been done before and to be honest applying the efi to the 500 was not easy,basic efi theory was put out the window,so i have invested alot of time and not to say money in doin this so with all respect cannot be giving away the specific details of the system.HGT tuning also dont disclose this information and not many people do.what i will discribe is the differences over carb etc,for starters this system is a fuel and igniton system,the igniton and fueling is fully tunable and reprogramable,we can simply change any tune at the push of 4 keys,the bike starts great idles mint,accerlerates fantastic,at this stage i cannot fault the efi.i have put it through some serious testing and have purposfully tryed to break it,things have faulted but i have corrected them,thats R&D.
as far as efi being a benifit over carb,i would say yes,but only just,i beleive a well tuned carb is pretty good,for tuning purposes the efi beats hands down,you can manipulate timing and adjust fueling to match your own riding style.obviously it is pretty limited with the carburettor.
cost,well if we say you buy a new carb,adjustable igniton(vortex) etc you will be getting up there with price,that stacked against doin efi the efi will cost more no doubt but you gain alot more as far as features go,so it does trully boil down to the individual and what they want from there bike?for me personally efi the 2 stroke brings it up to date with the offerings of fourstroke,the lower cost in maintanance and exrtra power,make it a bettter option to me,but that is just my personal opinion.we are currently putting together a tune to make this more tractable than the fourstroke,we have more power standard thhan the four at preswent so we need no more.fuel economy is just a mrketing hype for me,we have gained maybe 6% but hey its only as good as the twist of the wrist and somthing that never has bothered me,power is definately up but i will confirm that with dyno results to come but seat of the pants tells me for sure the power delivery is way more intense but ists hard to describe i woulsd say "neater" more refined than the carburettor.overall i am happy with the efi but i dont think it is what people will be hoping for i think in reality 2 stroke fans just want the 2 stroke to be in the 21st century with its design and efi,ing it definately brings it into that,plus i suppose it looks pretty cool,sorry i can tdisclose to much more on the details of the system,thanks...
Sorry am from new zealand,my name is mark barrett,my contact details are cr5001@hotmail.com
I wanted people to know this bike was done as it has had so many negative responses and so many people telling me and advising that it would never work.so this is for all those who give things a go,dont give up,nothing is never gained if never ventured....
hopefully we will have the 2 stroke back on top soon!!!!!
