build and rebuild get bet
Also while your at it pull the whole oil pan and check out your screen.
I don't think I would lay the bike down.
Hey guys! Thanks for the excellent info! I'm currently rebuilding a "76 XS650 that's been sitting outside for about 20 years, under a cover...it needs LOOOVVVVEEEE! To help with the oil question, even the late Gordon Jennings recomended using a 15-40 deisel oil, because don't forget...wet-sump motorcycle systems share the oil supply with the clutch and trans, as well as the crankcase. You need to use an oil that satisifys all 3 of these, especially with no clutch slippage, and keeping the gear teeth happy with enough zinc in the oil formula, without having to add something to the oil. Most desiel oil meet these specs, look up the JASO DH-1 spec and compare it with the JASO MA spec! The biggest difference I've found has been that the DH-1 spec allows for a slightly higher amount of ash (rated in PPM) than the MA spec. Soooo...what i did was look on the manfacture's website (Shell Rotella-t, Mobil Delvac 1300, Chevron Dello400) to see if their particular oil had the JASO DH-1 rating. So far, the only ones that advertise this is Shell Rotella-T 15W-40, or their T6 full synthetic 5W-40.Most of these oils have at or above the ratings and formulation to satisfy any motorcycle with a wet sump, clutch/trans/crankcase combo. Oh, and by the way...the most expensive of these is the Shell synth, at about $18-21 A GALLON! Most of them are about $12-15 A GALLON! The proper protection, and cheap price, PLUS availability at just about ANY truck stopo on the planet, especially in these time=a bargin for me! Butn dont believe me...do the research for yourself, if you're on the internet! Just trying to save fellow bikers a buck or two, especially when we're dealing with "vintage" bikes! (AKA old two wheelersIf you have the OEM solid copper washers, they're good for a very long time. Heat them cherry-red and quench to soften the copper.
15/40 diesel oils were a good choice because most of them carried very low molybdenum content (some moly compounds will build up in your friction plates and eventually cause slipping) and a high ZDDP content. EPA regs forced reduction of ZDDP awhile back, but it can be restored with a product called ZDDPlus. I'm currently adding 2 oz.of that stuff to a gallon of Shell Rotella 15/40, which, if I'm reading the dilution tables for the product and the VOA's for the oil right, gets the ZDDP level where it needs to be. Check www.zddplus.com . It's also available from Eastwood.
The nicest stuff I've used is Golden Spectro semisynthetic 10/40 or 20/50, but a price of around 8 bucks/qt. is hard to justify when you're changing oil every 1000 to 1200 miles.
you can get Shell Rotella-T at about ANY truckstop on the planet! At a pretty cheap price, too!Advance Auto Part's, or Auto Zone. Even Wall-Fart has it.
