New old Breva

[evguy]

I’m new to the group, I just picked up a 2004 Breva 750 FI that was in a barn for the last 7 years.
I’m working to get it back on the road.
After a few days, I have it running again but have a lot of work left to do.

Be sure to check for the half plastic fuel filter.

It still had fuel in the tank that didn’t smell too off, I connected the pump and ran it out, flush and refilled. I wanted to check it before throwing money at parts.
I thought I would need a pump and injectors, may have dodged that bullet

Injectors are easy to remove and send for cleaning. For that bike relatively inexpensive and close to the cost of cleaning.

Moving along on repairs, new tires, filters, replacing missing parts, cleaning and adjusting.
I went for a few test rides to check things out, probably around 100 miles, things are looking good other than leak on fork seals. They are ordered but probably will run out of good riding days before I get them installed.

Congratulations and Welcome!

You may wish to try cleaning the fork seals first.

In my workshop over the years, over half of the bikes with leaking seals, stopped leaking immediately after cleaning them out of insect wing and body part debris that was down in the seal.

It is a very cheap fix if it rectifies the leak!

I had tried cleaning seals then found damaged fork tube, so I need to address that.

If you need tubes Forking by Frank is by Chicago. I would also look that you have metal fuel filter not the 1/2 plastic. Stay away from ethanol if you can.

 

[evguy]

Changed out the fuel filter, replacement was steel. Thanks for the tip on tubes, I already found a pre owned set.

 

[scottmastrocinque]

That stanchion tube is not reparable. I think you may know this already. It will just slice up any new seal.

It must be replaced.

 

[evguy]

I found damage after ordering seals, used forks have been sourced.
Unclear how damage occurred, perhaps rust from sitting for years

 

[scottmastrocinque]

Precisely. That is corrosion damage.

Progress continues at a slow rate on the bike, I changed out the fork’s recently. I found the front wheel bearings were not looking great so I cleaned and greased. I changed all the oils, gearbox looked like a milkshake, bevel actually had water inside. Flushed and refilled.
I also fitted a led headlight and auxiliary light, added balance beads to tires.
Almost ready for riding season.

The bike has sealed wheel bearings. How can you clean and grease them without destroying the seals?

I got the seals out and did damage one a bit. It’s a temporary fix until I get some new bearings.

They are a standard bearing. You can get them from a dealer, MG Cycle, or a bearing supply house.

If you had some water in the gear oil, remember to take a look at it after first 100 or so miles, as if corrosion made some progress inside, it will migrate to oil, making it cloudy again, but rusty shade, not milk this time. Then you will have two paths, for brave and not-so-brave, either open the box and clean it off the rust including bearings replacement, or do another couple of oil changes every 200 miles or so, until most rust goes off - but knowing the way rust affects bearings, this is not going to be permanent solution.

I’m hoping that the flushing did some good but will monitor the gearbox and bevel drive.
I looked online for another final drive and they are expensive if found.
I didn’t hear unusual sounds in test drive, I will frequently change my gear oils as a precaution though.
