hi there. several answers to several questions there bud. I try and go through them as quick as I can.
yes there is a couple of photos of the cruiser I built being posted on the forum. the easiest to find is in my profile. look in my garage there is a pic of both my bikes the stock [term used loosely] blue gen 1 and the black modified cruiser.
power output of the EX generator is I believe around 120ish watts if you count up all the bulb wattages used on the bike and consider it uses around 15w to keep the thing running. there is a spare capacity of something like 15w [note it was never designed to run anything extra with a big current draw] so perhaps the most you could run would be may be a set of low wattage heated grips. or a phone charger. or power take off for a satnav. changing all the bulbs to LEDS depending on the actual size of the new bulbs should reduce the power consumption to more than half of what it was. so you would gain around 60w of power. it is just a matter of then calculating the draw from anything else you put on the bike after that. mind you as US models have running lights and a always on headlight [we have a light switch] these will have to be calculated as permanent draw on the power.
on a general modding note, it is far easier to do the mods while your still using the bike then you can establish what works or doesn't how far you want to go and how much it's costing. then if it seems to be getting out of hand you can stop at any point.
however if you plan to do a full on radical one off build this is not possible.
so you have to be aware of the pitfalls. namely it always going to cost far more than you think. it's going to take far longer than you think it will.
it is going to take up a lot of space while doing it. and when it's finished probably will not be worth in cash value the amount of money and effort you put in to doing it. often the net worth is less than the original bike was. BUT you will in the end have a bike like no other. no one else will own one and the pride and confidence in riding a bike you built yourself, in measurable.
however the more radical the design the harder it is to pull off. these bikes are born in the head from an idea. in practice the design will change during the build as somethings don't work well with other stuff you designed. you will find that once one mod has been done it requires further mods elsewhere, you will also make costly mistakes that have to be re-engineered later. the longer it goes on the more you question if it is really worth continuing during the hard times, of which there will be many. you think of giving up many times. but are spurred on by the finish line that gets closer. it's not something anyone should take lightly. give yourself a breather now and again and come back to it a new.
because once it is finished and you can ride it turning heads wherever you go with crowds gathering around it when parked wondering what the hell it is. is actually priceless. never think of selling it unless someone makes you an offer you cannot refuse. because you will never get your money back. but then that wasn't the idea in the first place was it
