the goat 642 Posted September 14, 2013 Report Share Posted September 14, 2013 I have just bought a honda trx 420 quad and the clutch has started slipping. Iv been told to change the oil which I did and when I put in castrol 10/40 (1 litre) it ran tidy (for 20 minutes) after giving it a little run I brought it back and went out and bought another 2 litres of 10/40 car oil and now the clutch is slipping so much the bike wont move. Does anyone know if iv used the wrong oil which it seems like I have or if I have uses too much oil? Any info appreciated Quote Link to post Share on other sites
Chid 6,639 Posted September 14, 2013 Report Share Posted September 14, 2013 i just googled it and i think youve used the wrong oil it should be 80w/85w gear oil Quote Link to post Share on other sites

BaldMan 26 Posted September 17, 2013 Report Share Posted September 17, 2013 Synthetic car oil has the wrong additives in and makes the clutch slip , use either 10/40 mineral oil or i used 10/40 shell motorbike oil in mine Quote Link to post Share on other sites

You have to use Bike oil, not car oil, even if it is the same rating.... Quote Link to post Share on other sites
taffy apple 32 Posted September 29, 2013 Report Share Posted September 29, 2013 the difference is buddy that cars have a dry clutch which doesnt come into contact with the oil, most bikes have a wet clutch which run in oil...if the oil is not for a wet clutch system then the plates cannot press together and cause enough friction to allow correct clutch engagement...always use honda recomended oil...

the goat 642 Posted September 29, 2013 Author Report Share Posted September 29, 2013 The quad has been running normal now for about ten days little adjustment on the clutch and job done but I did change oil and filters too.. Quote Link to post Share on other sites
