hey bud.. thanks for the link!   I think i modestly mentioned that i sell parts for a living elsewhere on this forum, which actually work out to my advantage.. i was able to use that manufacturer's part number and cross reference it against our site, and found the vendor's part number

217512  

We have it listed for $2 more on our site than the link you sent me, but... fortunately, i get stuff at cost... so that's pretty awesome... i just may get one of these...

 of course i would probably jump right on it if i didn't just buy a brand new points plate. I suppose i could always ebay it for profit considering i got that at cost too.  

ON ANOTHER NOTE:

i don't have any idea what changed....   none what-so-ever

I don't have a gas tank on it right now because the kid i bought it from conveniently broke the nipple on the petcock (two potentially dirty words in a row) that you plug the hose onto, so... the petcock is pretty much unusable. i have been conveniently using the gas tank as fuel storage though since of all the things i have, i have not 1 gas can in my garage.  

anyhow, i plugged in a hose to the carb and taped a funnel to the end, and poured some gas into it until the bowls were filled, sprayed some carb cleaner / degreaser into the carbs directly, put the choke on and hit the button....

after a second or two of cranking, a 3.5 foot long column of fire shot out of the end of the header (4 into one without a muffler on it) and i stopped hitting it...  

 i put more gas in it and hit the button again and the bastard FIRED RIGHT UP!!!!  ran for a second and died...  put more gas in it and kept enough gas handy to keep filling it as needed (which was constantly.. that thing drinks gas like it's going out of style)...

 anyway, it kept dying, which i assume was because the carbs need hella adjusting, synching, idle adjustment and everything else....   but, i think if i had a tank on it and could keep up with it's appetite for gas, i could make this thing run....

anyway, like i said about that battery, i got to do this about 6 times before it went dead.. so now i'm waiting for it to charge again for a few hours or over night considering it's 1am as i write this...

pretty exciting though...  

 oddly enough, this thing sounds like more of a riding lawnmower than my vintage 2 stroke 500... and it revs like one too...  that's probably because of the lack of a muffler.  my busa sounds literally like a pissed off VW beetle without the mufflers off of it...  


anyway, FOR NOW the thing runs... i'll keep it at that until i get my 75 model gas tank on tuesday and can Kreem it, put a filter on it and run some plumbing...

 i DO have a question about the carbs but i'll post a new thread about that...  pretty simple question though...
