Back at it.

Recommended Posts

Okay, I've been MIA for a while. Back in May 2018 I was working on the bike: 

 

 

I've finally gotten around to putting a few hours into the project again. This may be a long-term project. But today, with a little help from a friend we got the engine out and onto a workbench.

For what it's worth, the low (near zero!) compression in one cylinder is a mystery. I expected to find a bent valve or damaged valve spring. Nope. The head is 100% fine. All valve clearances were within spec before we started, and there is no visible damage to the piston crowns or cylinder walls. I will have to invert the engine and disassemble it to find whether piston rings are the problem. I expect that must be the case.

What is a good source for engine gasket kits, upper and lower?

Athena make good gasket sets for most models, much cheaper than OEM.

Athena do make good kits. I talked with their rep at the Motorcycle show in Milan about 4 years ago, and he told me they have an office in the USA.

If they cannot help, try these guys. I bought a VF1000R kit from them at a very good price.

They call themselves ItalyRacing (199750 reviews, 100% satisfaction) They communicate with you in German, and the kits ships from Poland, where I assume its produced. I was very happy.

Notice its says Athena, mine said KR. I  think the factory in Poland builds the kits for Athena.

 

Vesrah are good also. Dennis Kirk in the US carry them and they are found on E-Bay

Discounthonda who carry oem parts show parts #'s for the kits but the kits are not available. The individual parts are though at huge cost when added up.

Just a note, Dennis Kirk carries Vesrah products, including gaskets but don't stock the VFR750 Gasket kit, it would probably have to be ordered.

 

The part # is VG-5149-M.

Check out GPbikes ( https://gpbikes.com/ ) I have been dealing with them for years with my Triumph and they recently became a Honda dealer and service center with online parts ordering. They are located in Ontario.

 

Massive dealership and free shipping on orders over I think $50.

 

Look forward to seeing the progress
