Hi Looking for a speedo for my '88 XR600, but wondering what other models will fit that look like the origional (are the 250 and 400 the same speedo, or even a newer 600 model) so i can expand my search a bit. Did consider a trailtech type one but too pricey and i quite like the origional look. Are these hard to come by secondhand? Even considered a dominator one with rev counter, but wasnt sure it would fit. Also looking for bigger tank if anyone knows of one would appreciate if you let me know. Cheers
