Hi, I just acquired a stock 1980 SR500. Gonna have to call her "crusty" as she appears to have spent her life growing old at the Santa Monica beach. Oh Boy.... (SR stands for "So Rusty") It has been sitting for 15 years since moving inland. I rescued her from a dry garage but the rust has taken over. Surprisingly the inside of the tank looks new! Way better than my old Triumphs. I need to get her started. So need advice on a good interim cheap "flush-out" oil and a few basic "first kick" in 15 years pointers. Cheers!

Hi Sparky, sounds like you're taking on quite a challenge there. For flushing I would recommend any 10/40 that's inexpensive as you won't be leaving it in the bike for long. These bikes run smoother and sound much nicer on 20/50 and are one of the very few bikes for which the maker recommends using 20/50. On start up, if you have changed the oil first, you'll need to perform the check for an air lock in the oil system, by loosening the small bolt on top of the oil filter cover and seeing fresh oil seep out. (Don't fully remove the bolt, just loosen it to check.) If no oil appears here in a short space of time (maybe 10 seconds max) you'll need to kill the motor, take off the engine sprocket cover and you'll see a hard oil line meets the motor near the clutch adjuster. Trace the oil line down until you see a tang that secures the oil line to the motor and loosen it. Then, you'll be able to undo the two allen type bolts where the oil line joins the motor. When oil wells out, fasten the two allen bolts and you've fixed your air lock. Secure the tang underneath and repeat start up, looking for oil from the top of the oil filter cover. Job done! Best of luck with first start up and let us know how you get on!  |

Sparky, in addtion to Steves advice on the oil side of things.
Drain off any old petrol from the tank,flush it out with a bit of fresh fuel. Remove the carb and float bowl and give it a clean and blow out to clear any old stale fuel, heres where the starting problems may come in,if its a stock carb, things like rubber diaphragms may be in a serious poor state after standing for so long.
Before going into other starting problems lets see your initial attempts to fire her up.
Good luck !
Andy
