New bike from an Old uncle

Hi all! I just go my second 650. I had an 83 xs650sk, sold it. Shouldn't have. but oh well. And now I just picked up an 81 sx650h from my uncle/airplane mechanic. It has only 7k miles!! The bike has been sitting in his garage for the last ten years... he didn't drain the gas. So, I have been cleaning crystalized gas from everywhere and replacing only what is destroyed. I'm having problems getting the right side to run?? oddly enough a few days ago it was the LEFT side not running?? Well, so far only the air filters need replacement, unfortunately mikes is out of the OEM filters at the moment. I'm going to check with 650central.com
Oh, and my dad has an 80 xs650sg... that he bought new and he brags that it still runs like he just got it Cool

Anyway, I have been reading a lot of threads and decided to join. looks like a great place!

Good luck finding the OEM air filters without contacting a dealer. I waited awhile hoping it would be restocked but it never happened. I had to order a pair from Hitching Post which ordered from Yamaha. Its tough finding it elsewhere. Here's a site that has a reasonable price:

Its under Intake.

if you just have to have stock go for it. i got a pair of the oval k&n filters cheaper than a pair of the stock filters.

by the way, welcome aboard. my 75 was doing the same thing. one side then the other would run. combo of carbs and ignition. i replaced the points and coils. cleaned the carbs several times. runs ok now, if i can jst get it to stop smoking i'd be great, probably needs rings.

Thanks northernplains for the link. I'm going to pick those up.
I took the carbs apart again last night and found bits of rust... probably(definitely) from the tank. So I'm going to try the electrolysis procedure to clean that rusty tank out. I'll post in Fuel with some picks as it goes... I'm thinking 10amps should do it.

don't forget to replace the fuel lines as well, they will flake off bits also

murph; Electrolysis will do a great job for you. I found that 1 Amp of current flow worked for me.
Do a Search under..............."Clean out that Rusty Tank"........it gives the details of how I cleaned the tank on my 78 SE.

What Happened to 650rider.com?
