Is h1r slower in all applications? I would think they would have difficulty selling the stuff for racing applications if it made everything slower.

It's sure caused issues with everything I have used it in.
Years ago Belray had a pretty good reputation in MX, but that reputation was earned prior to H1R. Can't say if there other oils are worth a damn or not.
One other thing to consider is most people don't know how to tune a carb or do any testing so they would never know.

One other great smelling oil is Golden Spectro original formula in the black and gold bottle. I still remember the smell of that stuff as my dad used it in his dirt bikes in the early 80's
 
I forget now ,but why do we not want castor ,like 927 in a saw ? It worked good in my big bore 250r ,did leave some black spooge at the exhaust joints on my pipe though .
 
Saws are fueled (HP2), chains are sharp, and the beer is cold

Some had bad buildup with it. I didn't notice anything crazy in 4 gallons of mix I used. It was hot weather and I was milling some with the saws.
 
Does anybody know if they still make LawnBoy 2 stroke lawnmowers? I wouldnt think so with all the emissions stuff going on. I remember running those probably 30 years ago. You didn't have to worry about bugs in the near vicinity if you bogged the motor at all while mowing. Some guys swear by those things and seem to almost have a cult following....Lol. Anyone still running one?
they stopped putting 2 strokes on mowers in 2003 because of emissions.
now they make plastic junk I have a few lawnboys I have overhauled and use but parts are neither cheap or easy to get when it comes to some things.

I have a duraforce commercial and it's pretty much a pos. Looking for a M series which had a Suzuki motor.
