ST 1100 burning oil in cyl 2

[Jglan10 (Onesie)]

I have a 95 1100 it's been using oil for a little while it has 124000 km but only cylinder 2 plug gummed up I was wondering if they have any comon problems

replace the plugs, and see if it re-occurs. If not the go ride..

If it does, then further investigation will be required.  Only three main ways for oil to get in to the cylinder to be burnt..

1.  Thru the crank case breather.. draws oil vapor through the intakes for burning.  Other plugs are clean so not likely that excess oil is getting in this way. 

2.   Valve guides are worn.. Head will need to come off to check the slop in the guides.

3.  Worn rings.. Oil is getting past these. noraly this would also cause the the sump to pressurise and get oil going every where. Engine strip down to confirm and fix.. Probably cheaper to re-engine. or replace the bike.

I agree with Brock, if the oil ring is broken or worn, even if it's only on one piston, the motor needs to be pulled down to replace it, and if so you might as well do the rings on all pistons + whatever else is worn.................could be very expensive unless you have the expertise to do the work yourself, and have the necessary tools to do so!

You need to do a compression and leak down test before you start pulling anything apart.
 Are you sure it is oil? Does it emit blue smoke from pipe on start up? Does it puff black smoke on hot idle? Does it foul the plug enough that the cylinder doesn't fire?
