I 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.

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 plugs

I should have checked this thread out when I first joined! I have been running 91 octane in my X. It's performed fantastic, but I will not be running anymore of it. If Honda's engineers say regular, that's all I need.

I gotta say, Chicago-Spike, I always find your posts informative, and want to say thanks for the info you share :thumbup:

Purchuased my '03 1800s in '05 as a leftover, and like alot of the other posts here "nothing but the best for my bike" ran 93. Then after the bike had around 1k miles on it I went on a 250mile trip and decided to save $ and run 87. Noticed the bike was running smoother at low speeds, with no loss of power. It also seemed to run cooler, but that could just be my imgination. Since then it has only had 87 in it, and now has 9k miles on it, with no plug problems. Nice to know it was not just me that found this out.

So now what do I do? Just bought my VTX 1300T today and the last "tip" the salesman gives me is "Always run premium gas". Bike has 70 miles on it. Which gas?

You don't listen to salesman is what you do. As said, the VTX was DESIGNED to run on the lowest octane fuel available to you.

That Toyota "must" run much better on higher octane !!!!

If not then WHY was Michael Waltrip and his entire Toyota team so severely punished for using OCTANE booster at the Daytona 500 ?
Cars are very differet from the VTX. Car ECU/ECM have the ability to read what fuel is in the tank and adjust the engine timing to better use any octane from lowest to premium. The VTX ECU can NOT adjust timing

Again, if you could adjust the timing of your VTX, yes you could benefit from high octane fuels. But you can't, so it won't do a darn thing for your VTX.

If I'm correct...

The owners manual recommend regular unleaded, which is what I've been using.

If I have performance issues, I try a different station to see if it was the gas or not.

In most case, the regular had worked good for my bike with occasional performance "hiccup" from certain station's gas.

In the past, I owned a street-rod '78 T/A with higher compression, 11.5:1, and that engine loved the high octane gas...eliminated spark knock/preignition compared to the regular octane gas.

Unless you're having spark knock with your bike's engine, I'd stick with regular unleaded...especially with these rising gas prices.:dontknow:

Some people would recommend running a tank full of premium occasionally to "clean-out" the intake & piston of carbon build-up on the valves , intake runners and piston head:dontknow:

Opinions vary...:doorag:

Never checked your valves either? Good luck with that!
Nearly 6 years on nothing but 87 (or lower in the mountains) and no issue but proper maint has been done.

Great post, Spike.:bowdown: I, also thought old school when I bought the X in '05. I ran high octane until I got on this forum and started "learnin'" correctly about the care and feeding of the X! Most of my old bikes had been high compression and benefitted from higher octane, especially in the woods. I've been running regular for several years in my X with no problems and the power and mileage is good.:tools::thumbup::agree:
Now for my cheap shot as a Central Illinoisan! If your bike has a motor, I doubt if your big concern is with octane!:joke:(maybe wattage, or voltage):yikes:Keep the shiny side up, buddy!:beer3: Hope to catch ya at an M&G.

Amazing improvement with 85 octane

Read your post over the winter Spike and decided to try 85 octane fuel. I was using 87 & 88 before but thought I would try 85 since that's what is sold in a most places around Utah. Last year I could go about 150 miles on a tank (5 gal), this summer I've gone 200.

No pinging, power is at least as good, sometimes I think it's a little better.

What Octane Gas in the VTX?

I had a power comander put on my bike and before I droped it off I called the shop and ask the mechanic what gas he wanted in there so when he put it on the dyno it would be getting max power and he told me he always recomends 93 Octane. If I go back to 87 do you think I need to have it tuned again?

If you do need a retune, have it done somewhere else unless they are going to do it free because of the bad advice.

No, just switch back
