Honda TRX400 Brand New Clutch Oil Q&A

Is it better to run a semi-synthetic in a 2005 Honda TRX400 with a brand new clutch, instead of the factory GN4 oil?

John Talley: That’s what I ran in mine. I had an 08 400EX and I always ran the semi-synthetic oil in that gold bottle that I’m so fond of. I’ve used it in most offroad machines or my motorsports machines, so that’s exactly what I would run in it, and I would recommend it. And it plays well with the fiber clutch plates that are in there, so yeah that would be the one to go with.
