I have a 2004 Yamaha Blaster and once in a while it spits alittle burnt oil out of the exhaust, i was wondering if somethings wrong or going wrong or if this is just a normal thing for 2 strokes. Can somebody please help me out.

Thanks

 

Two strokes usually leave oilly residue on the end of the pipe. Does it spit the oil out when you rev it up. when you rev up a two stroke it creates turblence and may pick up some oil that has settled in the bottom of the crankcase.

 

Sounds like some serious carbon build up

have you ever changed the spark plug? perhaps your oil injection is a bit rich or your bike is jetted a bit too rich too


2 strokes will spit out oil, but you shouldn't be able to see it like you discribe.


First thing I'd do is change your plug and repack your pipe or burn it out if it's stock. There are pipe cleaning services out there that'll remove carbon build up and fix dents etc....or you can plug on a Toomie, pull your oil injector out, block it off and go really fast [img]i/expressions/face-icon-small-smile.gif[/img]

 

Yah i talked to the local ATV Dealership and they told me to change my Spark Plug and i did and it helped. The problem wasn't that bad it just spitted alittle oil out. After i changed the plug that seemed to help. Thanks Guys for your help
