My father just drained the oil for his 1989 Yamaha Moto-4 350cc ATV and was curious if it would be safe to replace it with synthetic oil. Any help would be appreciated.

sure as long as it's atv oil. keep checking oil level before every ride. some peoples machines have started burning oil with synthetic oil and some have no problems at all. good luck

I agree, I think you need to make use it's ATV oi with all the additives. Synthetic doesn't break down as fast.

      Need help 2008 Yamaha Big Bear 250
      By Dee Morris
      I bought my big bear in 2009, never had a bit of problem with it until last year. It quit starting but still would click when I tried to start it. I replaced the solenoid, the cdi module ( it was burned on one corner) and this year replaced the battery. I have all lights but still will not start and I do not have the clicking when I try to start it. Can anyone give me any ideas what to try next? I haven't had any luck finding videos about the 2008 Big Bear. I'm trying to avoid the expense of sending it to the shop.
