I have a 1981 Triumph Bonneville T140ES also. It runs great but the color is blue with dark purple shading the back of the gas tank and covering half the lower side covers. I also have the Bing carburetors. Looks like there might be a few out there. I was told they were very rare and not many were made. I listed it for sale on Craigslist, Denver, motorcycles from Fort Morgan. Take a look and let me know what you think?
