ok guys i posted up a problem a while back about my sr500 not being able to rev past like 3k rpms. well the bike is finally with me again and i have to report it still has that same problem. one thing that i noticed though when i pulled the spark plug it was cover in soot. well i am guessing the bike is running rich. so now my question is how do i go about remedying this problem cause i really dont want to take it to a shop. useful suggestions would help me out greatly. thanks. cheers

sorry gotta bump it up. anyone else have any suggestions?

yeah i checked the oil level and thought there was too much so i drained a little. sounds like you know the bike. the oil does run through the frame. whenever i can work on it again i will check the oil level to see whats up.

hey guys i justed joined the site in hopes that someone could help me out. last year i was rewarded with my dads 78 SR-500. its an awesome looking bike, the deal was if i could get it to run then it was mine. long story short it took replacing the battery, a new spark plug, cleaning out the carb and buying a new needle valve to get it to turn over and run. so i once i get it running it was blowing out black smoke. my dad suggested let it run for a while and just in case its needs to get all the old junk out.(it hadnt been started in 10+ years) so i thought it might be old gas so i drain the tank and carb to fill the bike up with some new gas. well its still running like that and if i try to take it out it starts to idle funny and dies. plus it wont rev past 3.5k i believe. whatever suggestions you guys have that could help me out would be appreciated. one of my goals is to get this bike up and running so i can drive it to work this year. i need your help.
