Older French build....please help!!!

So I have had this bike for a bit now and it begining to haunt my dreams...If I dont start working on it now I could be in trouble! Its an old motobecane from the 80's and I want it to look flippin sweet...a new paint job is in order, but I am pretty good at that. Anyways my BB is for a cottered crank...whats the best, perhaps most cost effective way to fix that? (I wana go cotterless!) Other than that I am open to any and all suggestions down to the handlebars and even paint color.

thanks all

French threaded bottom brackets are really annoying because they are so obsolete. But I do love french frames. You can buy phil wood bottom bracket cartridge cups and use a sealed cartride bottom bracket, or you can look aroung for some nos TA cups and an axle, but both these options might end up being a little pricey. If you have access to used parts, and the cups are in good condition, some japanese axels meant for italian threading will fit, but I cannot remember which ones and what sizing. Sheldon Brown is the best info on french bikes, but his site seems to be down at the moment. French threads are 35x1 mm, but I think that motobecane used swiss threading which is the same size, but the cups are threaded differently.

only some motobecane frames are swiss threaded. as i understand it, it's the later 70s and (possibly) early ass 80s. both swiss and french threading went out the door in the early 80s. swiss is different from french in that the swiss have one cup left threaded and one cup right threaded. with french, both are right threaded.

just take it to a shop, have them take off your bb, tap new threads (so you can use any bb), and get some bmx cranks. sould be $50-$75 total.. depending on parts

Won't tapping new threads into the bottom bracket make it too large inside and not be able to accept a new bb?

Harris has some BB spindles that supposedly fit french for about $15. Sheldon Brown is a great resource and occastionally answers emails. I'm rebuilding an old french follis and emailed him with a couple of questions, he got back to me the next day. He has an affinity for french bikes.

Yeah yeah yeah! thanks for the help so far (that goes to everyone) but replacing the spindle seems like the most logical and cost effective way to get on the road...now i just gotta get me one of dem spindles...I gots my girl looking for one from some knowlageable folks in NYC tomorrow. (she must really love me) If anyone knows of the specific spindle i should get hit me up, I'd greatly appreaciate it.
