Oils

Right now i use a 10w 40 oil with my stock clutch.........should that be a problem? And when i get a new clutch should i use a different oil?

Also how do you know if you need a new clutch basket?

Oil will be fine, and if you do the clutch yourself just look at the basket, if it has little grooves worn into the fingers then you should probably get a new one. If you have a 99 and its still original I would just go ahead and get a new one now if you can afford to. Might not be a bad idea to upgrade to a billet one. If you want to stay OEM, then I know most of the racers on here that use OEM replace them about once a year.

alright because i saw on another post on the 400ex section that someone was using a different oil so hit clutch didnt slip....i'll just do it right the first time and get it all...expencive though!

stock basket, tusk clutch plates and EBC springs from RMATV ;)

ya think? doesnt sound bad to me....i heard the tusk plates are tough too

The oil you are using is fine. Clutch slippage due to the incorrect oil is normally caused by using oil with friction modifiers. Just curious, what brand of oil are you using?

[Crazy400EX]

super tech......if you've ever heard of that

[zephead400ex]

Does it come in a black bottle? Just make sure it does not contain friction modifiers.

[Crazy400EX]

no its a blue bottle..........where could i look on it to see if it does......:eek2:

[400exrider26]

on the back of the oil bottle or if the company has a website go look the oil up...

[RiderTRX400ex]

ive seen supertech, i dont think it has any friction mods in it..

[Crazy400EX]

good

Isn't that Wal-Mart oil? If so, I believe it does.....

Ones that are bad are the ones that have the little circle on the back (bottom-right usually) that says Energy Saving. Those can potentially make your clutch slip.
