1970 US90 project

[cirose]

anyone know what model this carb is? http://dratv.com/19ctcafik21.html

i've been searching high and low for it on ebay but cant seem to find an exact match. being from canada it would help if i could find one here vs getting it from the us and paying double! from what i can tell it looks to be a keihin pz19 variation of some sort. possibly from a 50-110cc chinese quad with a 35mm filter on it. hard to tell because it appears they have the brand name grinded off in the display pictures.

if not this one then can someone point me to an oem style replacement for an atc90? most i want to modify is putting my oem jets in it.

thanks again - Cory

Thought i'd give an update.. so far I have the 82 110 fenders but I am still in search of a seat. Literally none have showed up on ebay or locally since I bought the bike. At this point I suppose you could say it's going to be an ATC 90/110 looking build with balloon tires. I don't think she will ever be a museum quality piece I just want it for a conversation piece mostly.. something to look at in the garage or keep for my kid if I have any.

I bought an ebay carb and got the firestone replacement tire, solid rear sprocket and had the bike out for a little test run. these things haul ass! I thought to myself hmm... not too bad I suppose for a 90.. looked down and it was in low range. I bet these bikes will do close to 40 mph! I was too nervous to take it past 3rd gear on my street in the snow haha.

- Another thing i've noticed is the Firestone replacement tire its noticeably smaller then the ohtsu balloon tire... so I guess i will be looking for another rear Firestone or putting it on the front for now. anyone have any leads on one?

- Gas tank has been in the garage with apple cidar vinegar for a couple of weeks now. still showing rust though. gonna try fresh stuff again soon and hopefully get it clean some time this winter.

- Chinese carb came in and I didn't notice the choke was on the wrong side when I bought it.. it wouldnt fit on the bike without hitting the frame so I ended up grinding the choke lever handle off and I have it modified with a paper clip to open and close the lever....
