[debrock]

hey guys i was wonderin, im about to get a 400ex and plan to put a sparks or lrd pipe on and of coarse jet it with a kn filter and an outterwear on the box, being air cool will the ex over heat if i were to ride it all day up in the adirondacks... we usally ride them all day on dirt roads, some sand and mud. all imput would help thanks

the stock oil cooler is good from what i have heard but u can get omf air scoops for it to increase air flow when moving at speed and be sure to change your oil if ur not racing a 10w-40 is good but a 50 wait is some times too thick if the weather gets cooler like at night and your engine might not get proper lubrication

i wouldnt worry bout usin a 50 weight oil. Most of us on here use mobil 1 15/50w and dont have any problems. reason being, when you warm up your engine, the synthetic will thin up extremely quickly.

hey guys a igot a question for you. When i got my 400ex the guy was using valvoline 10w 40 and i wanna change to the mobile 15w50 is it ok just to switch? Thanks

I run a maxima non synthetic 20w 50. I have not had a problem yet, and it is what I was recommended to run by TC. :blah:

Finally someone that doesnt use a synthetic, your clutch will last longer, lol. Im not sure why everyone runs synthetic, no dealer, or local bike shop ever told me to use synthetic in a wet clutch system.

TC recommends a non synthetic oil to be ran with his cam. I believe it has a lot to do with how thin synthetics get. Even though it is a drop in camshaft, it is larger than stock and needs some good lubrication to keep from wearing out the rockers. I'd never run a synthetic period.... My quad is a 00, raced 2 seasons...still on original clutch!!! :eek2:

Synthetic oil is awesome! You have to use the wet clutch compatable types though. It's says it on the back.:D

So red cap mobil 1 15/50 wont hurt the clutch?

[zoom400ex]

i dunno but my 2000 400ex is still running strong on the pennzoil 10w-40......................i dont think i would ever switch ot synthetic

[pnut420]

I didnt use synthetic, I had sand in the engine, etc... It was still running good and my clutch got abused and help up fine.

Sorry to tell you this, but someone got you a little confused. You are talking about 15 weight oil not 50. It reads 15w/ 50.;)

And I have recently learned that Motorcycle grade synthetic oil does in fact allow the clutch to slip more easily than petroleum oils do. I know this cause I'm 6'2" @ 270lb and I can wring out a clutch pretty good, and mine would chirp and chatter with AMSOIL full synthetic motorcycle oil in it, and stopped since I went back to GN4 10w-40.:macho :D
