I keep hearing about using Mobil 1 ATF in Yamaha 426 forks.
Is this something that only works with MXTECH valving or can I use it in my unmodified forks?
Is it 7.5 wt oil?
Does it last as long as branded cartridge oils?
Mobil 1 ATF will work fine in your 426. The slighlty heavier oil makes your clicker adjustments more effective.
It is close to 7.5 wt.
Most likely it will outlast your fork seals.
