Good morning, I'm here again.

First of all, thanks Prez1967 for your words. I know that I'm not a expertise with ZR-1 mechanics but I hope this information and basic works will help other first owners with basic maintenance. For other big things I have my expert mechanic and here in the forum there is a big quantity of good and high level information.

In second place, last weekend I found one problem with clutch slave cylinder. I found one leak in the bottom part of clutch bell. First I thought will be oil leak from cranksahft seal to clutch but after checking the leak on the ground it was clutch fluid. Not engine oil. I checked clutch reservoir level and it was near to empty. Only two milimeters. I checked slave cylinder and I saw little leaks (I don't have pictures. I found that so late and I forgot to take pictures to the slave).

Next morning I talked with my mechanic and he confirms me that slave cylinder was still the factory one and near to thirty three years old...

I'm waiting to USPS for a new one to come to Spain. I will keep you informed.

Here you have my only two pictures from the area:

Still with the car stopped at home waiting for slave cylinder... I'm going to share with you other findings here in Spain.

New rear tire bag found in Madrid too. My original one has the top bitten by mouses. I don't know when and how... But the hole is remarkable. I'm looking for a good expertise upholsterer to remake the top of the tire envelope.

Here you have both:

With the same person, I found diverse little things with interest to me for the future.



One ABS Module, retainers for front calipers guide pins, ZF 6 Speed or differential cap and two aircon sensors.



And for last, one low tire pressure module receiver with two lights for dashboard panel control.

Still with the car in the garage waiting for the clutch slave cylinder. The piece is already in Spain. I hope that in a few days it will be solved.

Meanwhile, I put another photo taken by a good friend.

I'm back again with the roaring beast!!

Last saturday my mechanic (Toni94ZR1 here in the forum, more than good profesional and better person) change old slave clutch cylinder.

The problem was with the internal washer leaking in the little rubber accordion pleats, and this, in turn, leaking to clutch bell and to the ground.

Without problems to install new piece. After that, some minutes to bleed the system.

Now the ZR-1 is again eating roads... 700 km (435 miles) in a single day.

A few pictures:
