An indication of the head gasket is greyish white oil.Mon, 09 Apr 2007 05:21:05 GMTMADracing926http://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxI've now put a couple hours on it with no problems so I guess it was just over filled and I over reacted. The bike rips!Mon, 02 Apr 2007 08:24:36 GMTPat P Diddyhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxmy 250 does that also with no overheating i guess i should have mentioned that also. good luck with the bike.</P><P>jimThu, 29 Mar 2007 19:03:51 GMTmainiac racerhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxPS: Interestingly Jay also said he was more impressed with the 06 than the 07 as they changed the carb on the 07 and it's more boggy?Thu, 29 Mar 2007 08:40:41 GMTPat P Diddyhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxWell I brought it in to Powerwheelz and did a leak down test and checked compression and he could not get it to leak now. He said the bike was MINT in fact he was bombing around on it just before I picked it up last night and he was really impressed with it. His theory is the coolant was topped off and leaks until it's down to the level of the top of the fins inside the radiator. My 450 doesn't do that and I can leave it full to the top of the cap. Apparently the 250 is different. Anyway I'm knocking on wood that it doesn't happen again and I was crazy. It cost me $66 for the reassurance.Thu, 29 Mar 2007 08:39:15 GMTPat P Diddyhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxwarm up the bike just a little bit then do a pressure test on the radaitor,if the head gasket is leaking it should show up if the pressure drops fast. also a cylender leak down test not a compression test can show a bad head gasket.</P><P>jim.Wed, 28 Mar 2007 21:26:19 GMTmainiac racerhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxIf none has been added it may have been overfilled before and is now at the correct level after overflowing some.Wed, 28 Mar 2007 14:59:41 GMTdrivenhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxI took it to Powerwheelz today and it's not leaking for them and they can't find anything wrong with it. The coolant level is now down one inch from the top of the resevoir. They think I'm nuts but twice when I started it it leaked steady like a stream of pee after a few minutes of idling.Wed, 28 Mar 2007 13:52:30 GMTPat P Diddyhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxPat let us know what the final verdict is on that. My guess would be the gasket blocking the flow of the water, wrong gasket or put in wrong. I would also guess the water pump (for lack of a better term) may not be working for some reason. Either way I hope you get it fixed without much money involved.

I haven't looked at the spark plug yet as I have to take the gas tank off to get to it. I'm bringing it to a mechanic Tuesday I just hope it's not and endless mystery and a compression check will get to the bottom of it.Sun, 25 Mar 2007 20:47:40 GMTPat P Diddyhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxWas the radiator filled to the top when you started the bike? could it just be expansion?<br>A head gasket can put coolant into the oil, but it is possible depending on where the leak<br>is for compression to force combustion gasses into the water jacket and not into the oil passages.Sun, 25 Mar 2007 09:19:16 GMTMile Hill MXhttp://www.mainedirtbikes.com/newforums/Topic1313-8-1.aspxWhat's the plug look like?

I tried putting a different radiator cap from my CRF450 but that didn't work. Somebody told me it's probably a bad head gasket but another said that the oil should look cloudy if that's the case which it doesn't.</P><P>Any theories?Sat, 24 Mar 2007 18:23:26 GMTPat P Diddy
