Re: Oil Burning Cont.

[Bob Hadden <kbhadden@xxxxxxxxxxx>]

I'll bundle the reply to plpklt, Andrew and Seattle Dan into one.

The bike turned 2000 miles yesterday during the ride.  The first 500 
were easy per the book as I tried to stay within 4000 rpm.  No lugging 
though.  Burned very little oil during that period.  After the 600 mile 
service, I felt it was time to get on it a bit, so have been running 
per my normal style.  This is running up to say 5500 rpm or so to shift 
up and cruising around 4000 or so.  Occasional runs up to 6+k but I 
haven't red lined the motor yet.

The tail pipe is clean.  No soot build up to speak of.  There are no 
leaks.  Checked the air box last night.  Did you see the drain hose 
(actually a breather hose I suppose) on the left side going back to the 
valve cover area?  That hose is wet from oil.  The box is wet in the 
bottom, but nothing collected.  The filter is completely dry.  I don't 
think any of that is abnormal.

I think plpklt's stronger break in is probably the way to go on these 
motors.  Will know in the next 1000 miles or so if the oil consumption 
goes down.  I guess the plan is to get on it more rather than less, to 
get the rings to seat.

Seattle Dan, I would be interested in the micapeak guys conclusions 
about oil checking if it's something you can send my way.  Thanks
