in south carolina @ this time of year its not going to make any diff . The "alternative products" are SUPPOSED to be better at cooling , but thus far , few of them have made any other boasts. Its not like yer gonna leave yer bike outside too test an anti-freeze against the elements (unless yer real dumb)
For me, the most important thing...DISTILLED WATER.
if it were me , I'd just go with whats tried an' true , some stuff has been used for yrs an' yrs , an' some stuff is a little bit newer on the market.
Who can tell what the long term effects are for the newer products....they dont even know....how can they , its a new invention .
Distilled water can definately help thou....you'll have less build up , an' blah blah blah.....
In the end , the temperature around the critical areas is going to be about the same , no matter whats in there. Near the upper cumbustion chamber etc etc....hot things are happening . if you can bring the temp down a few degree's an' stop the fan from coming on....gr8 . It's still fuggin' hot in there .
A good oil is more important....if you ask me...
hav a good 1....RSD.
