hey, i bought a vtr250 last weak from a private sale. On the test ride i did notice a slight pulsing from the front disk, but the seller didnt tell me anything was wrong and because he was an older dude who is an aircraft technician, i trusted him and *stupidly* bought the bike. Riding it around after i bought it i could clearly notice the pulsing from the front when braking. Last friday i droped the bike in the school carpark and i think it was due to the warped disk and slightly slipery road. Because i think what hapend, cant remember properly, but i started braking to slow doun for a turn, and i was braking slightly hard, then sudenly i was on the ground next to the bike. while this could just be rider inexperiance i wast braking that hard, so i think whithout the warpage i would have been alright. Now the bike has scraches on the RHS, but nothing major. 2nd stupid thing i have realised that i dont need a bike and cannot afford it, so i want to sell it. now i understand that i did drop the bike and the price will have to be dropped, but i dont want to have to lie to someone about the front disk to sell it, so i am afraid i will lose a huge amount of money. i want to call the guy i bought the bike of and see if he will pay to get the disk fixed/replaced, because he seemed decent. but if he dosent want to fix it would i have any rites to get a refund on the payment because he didnt tell me about the disk? am i going about this the correct way? i figured calling him wount hurt, and he may pay. so any coments on my rites as a buyer? any help would be much apreciated. p.s. i havent had the disk cheacked profesionaly, but the pulsing is rather severe so i dont think it would be anything else.
