Don't follow me

[1RobAusdemore]

I have a 2003 EC250 it runs great as far as I can tell it always starts right up, hasn't fouled a plug in the 3 months I've had it. It has gobs of power that does sign off kind if early but it has a Gnarly pipe on it and I read those do not rev out well. My issue is if you are riding behind me there is oil splatters all over the front of the bike. There is also an excessive amount of oil dripping from the end of the exhaust. I try to mix at 50:1 the only carb adjustment is turn the idle screw up. It starts and runs do good I don't want to mess with the carb if I don't have to. Any tips or ideas would be helpful .

Make sure you shut the fuel valve off when you get done riding. If your carb is flooding it will fill your crankcase up with fuel and blow all sorts of nasty black spooge out until it gets cleaned out.

What 2stroke oil are you using? If it has a high flash point and you aren't riding hard that could explain some of it.

Amsoil dominator, that could be the case. It is street legal and on the roads I don't get on it much to keep the noise and front wheel down. Also on the trail someone is using my other bike which is a tw200 so speed is kept pretty tame.

Looks like amsoil dominator is a pretty low flashpoint so can't be that. How about transmission oil, do you notice any disappearing?

I will check next time I'm at my cabin where the bike is.

Dominator is high flash point. There is a good chance that can be part of it. I wonder if you are in a rich carb condition. Jetting is super easy on these bikes. You can change the pilot and main and needle without taking the carb off. Just unscrew cap and loosen boots. Twist carb bowl towards you and service. Simple and cheap jets cost less than $10 each and even though it runs nice it probably needs it done. Not sure where that chart came from but the flash point for interceptor is way wrong.

As with the dominator facts...

A friend of mine had a '99 KTM 300 that would splatter the rider behind him. I would always leave a good distance not to get all the black spots. Problem went away when he sold the bike

When was the last time you packed your silencer?

Put a down turn on the silencer outlet

 

[1RobAusdemore]

I have not packed it in the 3 months I've had it.

Ok so I checked the level of my oil and it was past the sight level when not running, when the engine is running the oil level is right in the middle of that little sight window. I know when I filled it I was careful to not overfill because there was too much gear case oil when I bought it. So gas could be seeping in.? I usually turn off the gas valve but there have been times I have forgot. I haven't taken it on any long rides just short rides around the cabin. How bad is it for the engine if gas is mixed in? I know it's very bad for a four stroke. I will do a oil change next time I'm up and see what I find. However I mixed my gas a bit on the lean side maybe 55:1 and there was less oil in the exhaust. I think my last tank could of been more on the rich side of 50:1.

It's more likely that oil would pass from the gearbox into the cylinder than the other way. Gearbox oil would also make the bike run really poorly and smoke badly, if it's not smoking badly then it's probably not leaking gear oil.
5 points on the mix ratio is nothing to be worried about.
I'd say spooge is a combination of high flash point oil and possibly a muffler that needs repacking. If it runs and starts well, has no issues with running rich, then it's probably not jetting.

 

[Jakobi]

The oil level changes because when the bike is running the gears and clutch basket is picking up oil and circulating it around the cases. When its off it pools up and reads higher. Totally normal.

I make a habit of putting a set volume of oil in, and measure it again when it comes out. Quick easy indicator to see if your bikes burning oil/picking up coolant/water.

I agree with Noobi. Probably a combination of slightly rich jetting, a high flash point oil, riding off the pipe, and pipe packing that has reached saturation level.

 

[1RobAusdemore]

Ok I am still going to change the oil and see how much comes out. I will get some packing material, any recommendations? And what oil has a low flash point for the Driving miss Daisy type of riding I usually do. And does repacking the muffler require a rivet gun? My bike is up north so I have to make sure I bring everything I need with. Thanks for everyone's help.

If your carb is slightly flooding the excess gas will go into your crankcase area not the gearbox. When you start the bike up it purges all the excess fuel in the crank area up into your exhaust and soaks into your silencer packing.
