fuel filters ?

[dustrunner]

I looking at a couple fuel filters for the big reds.. I found some that are 75 micron and some that are 150 micron... I know the 150 micron would filter better but would it restrict fuel flow at full throttle ?

You've got it backwards, the 75 micron would filter better (only lets thru 75 micron particles or larger). The 150 would almost definitely not be a restriction, but I tried an 80 once on a TRX300EX, and it caused fuel starvation, so I had to remove it. Depending what you're putting it on, you may be fine with either.
