Hi, I am a month into owning a ttr 250 93/94, my first bike, loving it and is great for NZ riding. I am taking part in a trail ride on Saturday, which specifies you have to have a sprk arrester, do i have one on already? if so where is it. i have down loaded the manuel online, which states one but is probably for a newer model. Check out the ride its Danseys Pass NZ.Any help would be much appreciated!
