Fork oil substitute?
I'm replacing my oil seals but I know I'm gonna get shafted if I go and buy "Motorcycle Fork Oil" and I am on the tightest budget imaginable right now.
I heard somewhere that you could use automatic transmission fluid as fork oil, specifically Dexron II. I was wondering if anyone has tried anything like this. My brother has a 5 gallon bucket of this stuff just laying around with nothing to do with it so as far as I'm concerned... as long as it will work, it's free fork oil.
I did some research myself on viscosity and whatnot, but it's quite confusing, especially since fork oil isn't really going to get hot.
I hear Dexron II simulates about a 7.5 weight oil when used in forks, and the repair manual says the front forks should take SAE 10W-20. So I figure I could put it in there and just put a little air pressure in the front forks to stiffen it up, since 7.5 weight would be a tad soft, correct?
Let me know if I'm about to do something stupid.
