Ok, I have had a problem with my motor running to rich. With comments of people who I ride with that do not want to ride behind me because of the exhaust fumes. Makes there eyes water and they get headaches. I get extreme carbon build up on my exhaust tips, a black coating inside of 100 miles that is thick, to where you can not see the paint. I have had a dyno pull made and was asked if it was a diesel because of all of the black smoke that poured out of the exhaust that filled up the garage. That was a HD shop and they got a lot of laughs from that.
I read the post and said what have I got to lose. I know enough that I know what rich is (to much fuel or fuel not being burned) plugs that come out black and full of soot. Even when warm rev the engine and see the black come out of the exhaust.
So I cleaned my ehausts tips and tried lower octane fuel and ran a couple of tanks. The result is almost 300 miles and I can still see the paint on my exhaust tips, NO SPARK knock, 3 to 5 mpg more, and it feels a little smoother.
My other option is a fuel controler, $200 to $500, that will automatically reduce the amount of fuel being used to make the engine more efficent. Resulting in the same effect as what I am doing now.
I read this forum a lot, I do not make a lot of comments, I am of the silent majority, there is also a wealth of information here to be used or not used. This is something that made some sense so I tried it and it works.
For all the wrenches, keep the information comming because I can still use your help.
