Trying to get ready for a 1000-mile weekend on the A10, and it's not doing right.
I put 1800 miles on it last summer in the UK and then shipped it here. Rode it for a few days, but the cylinder base studs loosened and blew out the gasket.
So I pulled the top end, freed up a gudgeon pin that was extremely tight in the small end, replaced all the gaskets, reassembled, set tappets and rode 25 highway and city miles into work.
Two things the bike is doing. One is that when I run about 60 or 65 MPH and open the throttle, I get very little response. The engine runs smoothly, but just sort of "bogs" and doesn't go any faster. Since we never really got over about 55 MPH on the back roads we were on in the IOM and Derbyshire and Yorkshire, I never tested this before. Needle position, you think?
The other is that when I come to a stop from a 65 MPH highway run, the bike will barely run, and sometimes cuts off. Accelerating back up, the bike runs very rough, missing, etc, and gradually smooths out and runs OK again. Spark plugs loading up, maybe? I oiled them pretty good when I fired the bike up wet-sumped and oil puked out of the breather after it had been down a month or so. I'll try a pair of Champion L10S in it and see.
The engine runs nice and quiet, tappets at .008 and .010 per spec, good compression, timing and point gap are on.
One more night of fettling and if it doesn't behave, the Guzzi will go play in the mountains instead of the A10 .... !
