I use Marvel Mystery Oil its a cleaner n lube.

Race teams use it as Race fuel has NO Lube in it.

Use it in all my bikes

 

I use Chevron Techron fuel system cleaner.

Techron Concentrate Plus is a premium fuel system cleaner trusted and recommended by many automakers to help restore lost fuel economy and performance. Its patented polyether amine (PEA) technology is unsurpassed as cleaning deposits from intake valves, fuel injectors, and combustion chambers. It is safe and effective to use in all ethanol fuels, including flex fuel like E85

 

I have been using Star Tron for the last 6 months after a friend's 2011 Glide had injector problems. Was using Seafoam prior but the Star Tron was less expensive and is said to have a more positive effect on preventing problems caused by Ethanol in fuel. I wasn't looking for a miracle treatment but just want to avoid any problems with any sub-standard gas. When traveling out west I used 1oz in every tank refill because I was never sure what I was putting in the tank (wasn't a big choice out there at times).

 

I used Gumout once but I never noticed any difference. I go it for half price when I bought some oil once. But I haven't used the oil yet.

 

I use Techron once a year never a problem

 

You are using a cleaner every time you fill up. Its called ethanol. Its a very strong solvent. That's why when the EPA mandated the fuel with ever increasing levels of ethanol, people where having trouble with fuel pumps and filters clogging up. It was braking up all the crud that had been left in fuel tanks and lines for years. Not to mention it was eating up some of the rubber fuel line parts.

 

Redline is top notch use it every 6 tanks keeps garbage cleaned up inslde fuel system have noticed 40 more miles per tank 2004 roadKing custom

 

I use it every time I fuel up by just using Chevron gas.

 

Seafoam every couple of months.

 

If you buy Chevron premium it has Techron additive all ready in it. If you buy cheap gas you'll see how your bike runs on that.
