okay so I have my quad at the dealership getting the valves done and stuff,so I just picked up this 05 crf50 and the kid told me it had a leak in the rear tire. So then the tire goes comepletly outta air so I said why not bring this tire to the dealer where my can am is getting serviced, I had a new tube in the box so I bring it there they want 30$ to put it on. So im like okay whatever do it, so then I get the tire back(after waiting 45mins) its full of air its readdy to go so I bring the tire home I put it on my bike I go to take the bike out for a spin flat again, what can it be I dont understand should I call the dealer or they gonna tell me tough luck?
