One outlet valve needed grinding, because the outer valve spring was broken.
The others were ok.

Found a washer and some debris in the oil sump *oops*, looks like a threaded part from the engine casing and some plastic or maybe surplus sealing compound.

Got new tyres (Bridgestone BT35 90/90 front, BT25 100/90 rear).

Some plastic parts had suffered from vibrations and had to be repaired (seat back, fairing) or replaced (side covers) and the seat got a new cover.

Replaced original brake lines with Spiegler stainless steel braided brake lines.

Recognized there is a problem with the rear break cylinder; has been replaced with a PS16 unit as the original PS15 was not obtainable.

During reassembly of the cylinders / heads we noticed some (almost) ruined threads in the heads, which were helicoiled then.

After first reassembly, the beast was leaking from the cylinder foot gaskets (sigh).
Took off everything again, got all new gaskets and o-rings, added some silicone sealant (Yes, I know, be careful with that), put everything together again.

On September 28, 1997 we finaly passed technical examination and registered the bike.
Some strange noises still coming from the mill, and there's some wobbling while accelerating in second and third gear - we'll see.

On July 10 1997 we found another Imola, built in '84, in good condition.
So that one became our second Guzzi :-)

April 2001:
The wobbling came from a slightly bent rear wheel which we replaced in the meantime.

The strange noises seem to be normal.
At least the engine is still running :-)

As the bike was burning more and more oil, we have taken it out of service for the moment.
Either the engine will be overhauled after the Le Mans is finished, or another engine (preferably V65) will be put into the frame.
