5thave 3 Posted December 26, 2019 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. Quote Share this post Link to post Share on other sites

5thave 3 Posted January 2 What is a good source for engine gasket kits, upper and lower? Quote Share this post Link to post Share on other sites
Mohawk 580 Posted January 2 Athena make good gasket sets for most models, much cheaper than OEM. 2 Quote Share this post Link to post Share on other sites
FromMaine 122 Posted January 3 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. http://www.athenausa.com/catalog/motorcycle If they cannot help, try these guys. I bought a VF1000R kit from them at a very good price. https://www.ebay.de/itm/KR-Motorcycle-engine-TOP-END-Gasket-Kit-ATHENA-HONDA-VFR-750-R-RC30-88-93-/172397945569?hash=item2823b7e2e1 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 http://www.vesrah.tokyo/product-line/gaskets/ 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. https://www.discounthondaparts.com/oemparts/a/hon/506ca710f870023420a3fb70/gasket-kit-a Quote Share this post Link to post Share on other sites
5thave 3 Posted January 4 Thanks! I will check out those sources! Quote Share this post Link to post Share on other sites
FromMaine 122 Posted January 4 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. Quote Share this post Link to post Share on other sites

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 Quote Share this post Link to post Share on other sites
