Well I've just started my learning curve of trial's riding and now I'd like to ask a few questions.Picked up a 1986 ty 350 with a 250 top end over a year ago, after a carb clean and a trans flush I was able to ride it for 6-8 riding hrs. However first start up's are getting harder and harder [ to let you know I'm a tech at a yamaha shop 20 years] so I'm sure she's a little tired and I'd like to freshen her up.Is there any one stop shopping for parts or do I need to search here & there on the web?
