I am the 2nd owner of an 03 F90tlrb 61 p l carbs.I estamate hrs. @ 4/500.I was thinking of replaceing the timing belt ,when I tried the local yamaha shop didnt have it in stock and they said they rarely replace them i.e. they last forever?what do you recommend.oh, the belt appears to be in very good cond.but i wonder about stretch and would it run better w a new belt?I also wouldnt want it to fail obviously.thanks always
