Hey guys...
Anyone know the oil capacity of a TRX350? I changed the oil yesterday and worked off of a TRX300 manual. It called for 2.38 quarts. It then dawned on me last night that a 350 probably requires a little more oil. Anyone got a 350 or manual?...ps, my 350 manual hasn't shown up yet. I won't be bothering folks with this type question after it's here!
Blessings,
Jeff

 

my 05 is 2.1

 

My 03 and 04 both take 2.1qts. also. I'd start with 2 qts., go for a short ride and check your level. Or you could call your friendly Honda dealer.
