The other day I got some fuel where I usualy don't! Rode about 12 miles shut done for half hour, when I started it again it has run crappy ever since! Figured it was bad fuel. Pulled fuel pump cleaned it ,cleaned tank out and I am on 2nd tank of clean Chevron Premium with K-100 fuel and injector cleaner added! Still is not right, it idles rough and die. And cuts out while riding, but it comes and goes which has me confused! When I check the plugs they are dark carbon fouled so its not starving for gas but also It is better when I give it a little throttle! I torn it down to the air filter and it was full of oil and white milky looking crap and I think the vent tubes are plugged with that crap also!! Would this make it run like I described? Forgot to say this is an 2001 1800 goldwing trike!!!
