can i run synthetic oil in my 250 sport???? iv been reading some posts about it and i heard that ams oil was the best and it is relly good for ur cluch and it has significant power gains... is this true????? and what ams oil would i use in my 250???

you can run synthetic oils but i woundn't waste the money, you won't notice any power gains if thats what you're after, i've changed to synthetic before and only to have oil leaks, changed back to conventional oil and the oil leaks stopped, also the possibly of clutch slippage, since the synthetic oils are slippery and have more additives, theirs no oil filters on your 250, you need to keep the oil changed often, every 20-25 hours .

After I broke the engine in on 10w40 Valvoline, I've been running Mobil 1 15w50 in my 250 Sport. I've had no problems with clutch slippage, or oil leaks. No more oil than it holds, I change mine more often. I go maybe 10-15 hours between changes.

Synthetic oil can cause leaks since it will disolve sludge and such left on seals that was keeping them from leaking. But the seal had to be worn in the first place.

I run that oil in both my quads, with no problems. Just my .02 worth.

in hot climate you should use a 15w-40 or 20w-50 motor oil and in
cold or cool climate use a 10w-30 or 10w-40 conventional motor oil.

this comes from your owners manual,

i would run ams oil for your syn oil but the one person is right you have no oil filter so you have to change it a little more .the automobile oil is okay but it is not wet "clutch compatable". my polaris came stock with sys oil i switched my recon to it and have not switched my eiger over to it yet.

I would save your money and just use Valvoline(or any other major brand) 10w-40. If you have some money to burn you can use Amsoil 10w-40 Motorcycle oil. Its what I use in my KTM. My Jetmoto's and Honda air cooled thumpers all use Valvoline 10w-40. I have never had a clutch or tranny related problem with them.

yea i bought some to see how it works i havent put it in yet but will report on how it is... and the cluch wont slip because its motor cycle oil so its biult to not do that.... yea i read the oil bottle and it says used motor oil has been known to caulse skin canser thats not good i always get it all over me !!!

i road today out in locale pits the quad it so much quieter and shifting is so much smoother and the cluch no longer grinds and it does seam to have a little more umphh when climbing and i have a justed the shocks and tire pressure and it jumps so nice i can get 3-4 foot of air but i just cant jump far

From what I understand, you are suppose to break it in using the regular and then it's a good idea to switch to synthetic after that. In my 150 gy6, I've been using the amsoil 4-stroke synthetic oil for motor sports. It says it's wet-clutch compatible. The quad has been running very smooth and won't overheat even though this thing is just fan-cooled. I haven't noticed any actual permormance improvement, but I figure I might as well keep using the stuff so the quad might last a while.

dont waste your money,regular oil is fine when these china motors decide to go there gonna go no matter what oil you put in them. if you change the oil like your suppose to it should last but then again they are from china.
