US90 interchangable part

[mike from long island]

how interchangable are the US90 with the later models?? i have a 76 parts bike i am about to trade off. and if some parts work i may hang onto it? anyone have any clue?

Off hand Mike I am guessing around 75% of the machine to interchange ,off hand -exhaust..tires.. tanks /72 and later.. Brake lever.. recoil...carbs will work!! There's alot of stuff that will transfer but not to be orginal to the US model!!!

you can put the whole rear axle assembly in your us 90 to get rid off the balloon tires you can never find?

i put the whole axle assembly from a 1980 atc 110 in my 70 us90 so i could use regular wheels without adaptor.

okay thanks. i want to keep it as orginal as possible. or at least use used US90 parts on it. the exhaust on mine is bad plus he welded a briggs and straton muffler on there. i have another member i am going to call once i get a good list up. i want to spend a lot for good parts,but at the same time is it worth it to me??? i dropped $450 on tires and still am having trouble breathing lol. it was either that price or fight for them on ebay. so i drop the nut and did it. very pleased with them too. all hold air fine and one is pretty new. two of mine were orginal with serious dry rot the other was different with dry rot. i guess ill have to weigh out my options. thanks

more orginal = more $$$ on resale :beer

Thats soooo correct on keeping it all original .. What year is the 90, I have a 72 green one with the yellow on the tank,thats a future project,but with the price's I am seeing on those 90's clean like you 're going for ,I mite make that a prority sooner than I expected,LOL !!!

mine is also a 72. i bought it from the orginal owner. he even had that card you get. but he wanted to keep the card. this one is a keeper.i just want to get it up and running better so i can play in the yard.after a few other projects are done i would like to see if funds are avaliable and have vintage do a clean redo of the bike. i dont know if he will redo a bike to a nice rider or if he is a full blow restoration guy. either way i want to clean it up nicely. thanks for helping me decide which route to take. heres a few pics. last night i put the new tires on just havent taken any pice yet. this is how i got it.

actually it took only two weeks to find all three tires for the US90. another member contacted me about a place he knew had a few sets. it cost more then the bike. but like you said, they are hard to come by. so if you want to play you gotta pay!!! plus with the new tires on, the value of the bike just went up.a bike with 3 flat tires unfixable,with 3 new oem orginal tires that all hold air with no dry rot. well i am guessing the value is less then all i paid so far. but to me PRICELESS!!!

Looking nice! They are fun to ride too... get it going! I got mine by trading a 225DX that was a real dog. I wish I'd seen it earlier. The guy said it sat outside for 8 years!

I can't wait until we have some measureable snow to take mine out again! Here's some pics of me playing in the yard this past summer.
