What about running some cleaner through or even some tranny fluid to help keep the carbon and gunk down plus the smokes great..lol... I run a little injector cleaner through mine occasionally , my rider is at least 16 years old... Plus I do mix fuel stablizer in every gas can and it has cleaner in it also...
I actually run a little atf in my fuel. I've done the old school thing of dumping atf and water down the carb. I have a can of turbo cleaner I'm going to try on gun carbon one day. I'm no expert but I wouldn't think gas type/quality would affect the exhaust valve as much as the intake. I would think oil quality would be the factor on the higher heat exhaust valve. Thoughts?
Here we can and you probably also can get the methanol free gas... It's a little more expensive but I run it in my 2 cycle stuff....Sunoco 94 and a good synthetic and you won't need any Wally World snake oil additives.
If you really want trouble free, burn avgas.
Bad gas, after sitting with old fuel which smells like varnish it will coat the valve stem and bind the valve open allowing the piston to smack it , this is a bi-product of ethanol ,use stalbil if the fuel can not be drained if it is to sit without being run at least twice a month
What he said^^^^^
+1 for seafoam Or if you can find it a lead gasoline additive lead in the old days gasoline is what lubricates valve guides and valve stem’s now that we’ve removed it there is little to no lubrication in the fuel and results in higher temperatures increase valve wear and the dreaded sticking valve
