Using premium will not fix the problem. You must have read the article wrong. Premium is NOT needed in the VTX. Using it only makes the oil companies happy and your VTX will run worse and get worse fuel mileage. It also will foul the plugsI read and followed your technical info with photo's for correcting the ground problems. When I read you description of the symptoms I said he has been riding my 02 VTX 1800c. Last night I took the gas tank off and did all the steps in your article. I had already done the battery thing and my bike has the "correct" system ground bottom of engine near oil filter.
I installed a set of 03 heat range plugs due to all the info that says 02's had too low heat range plugs. I also bought 4 gal. of premium and poured it in the bike last night after reinstalling the gas tank. When it warms up this afternoon I am going to take it out and hopefully my problem will be fixed!
Thanks for the article which I printed out and used at the bench with photo's and all.
I will let you know if all is well after the test ride.
My name is Fred Owings by the way and I am gald to meet you.
