Mayonnaise in exhaust

[murp]

Guys.... Looking for advice.... Started the LC today.... It's not running strong on r/h cylinder and there's a hint of mayonnaise in the r/h exhaust pipe.... Would this be head gasket or maybe something else..... When I drained the coolant there's no oily residue in it, but the trans oil looks a bit strange.....

What does everyone think...

Cheers 👍

The spark plug on the right is out of that cylinder as well

Water in the trans could be simply a water pump seal or even the water tube oring.
But it could be something else as well.
Time to disassemble the engine to see !
Winter and Lockdown makes this a reasonable time to do this

Is the bike in a cold / wet environment ? Could simply be condensation in the exhausts ?? Think your trans oil may need further investigation though .

oh ! And have you checked the water level in your radiator ? Has it used any ?

I dismantled the engine today... First time ever..... Not too difficult, but there appears to be foam (bubbles) in the trans oil..... Don't know if it's the seal or the o ring, both appear ok, but I will change them and the crank seals anyway...... My dilemma is how do I know if the crank needs a recon and a rebore too..... Don't want to do these jobs if really not necessary.... I need someone to cast an eye over them to see if they are serviceable..... I'm near Basildon Essex....cheers 👍

Could of been o ring on coolant pipe which goes into top crankcase from water pump, does not explain milk in the exhaust though? So if engine sounded ok mechanical a full seal,gasket change would be ok.

I think the only way to get transoil in your exhaust is a leak crankseal.
