i went to 2 tire places, my honda dealer, and a shock rebuilding place, and no one has a nitrogen tank to refill. tomorrow im try harley davidson and a bike shop. if not, then ima just fill it with air. but the shock guy tried to bs me that i had to pay 200$ to rebuild it all this other crap, and im like im not paying 200 to rebuild a 30$ shock lol. i hate ppl who dig for money.
