Ok...so I bought this Yamaha YZ250F last August and took it to Watkins 5 days later. 6th lap, dug in too deep, crashed and broke my collar bone. Thinking MX is not for me. So, I have been talking to people about trail riding. My muffler doesn't count as a spark arrestor. Anyone know how to go about getting one? Is it a part or do I need a new pipe? Most importantly, do you think I should get rid of the YZ and look at a WR or something I can take on the road if my MX days (or day) are over?
