We just had a long discussion about oils. A good cheap oil to use is Rotella T, and you can get it at Walmart or Advanced auto. Honda oil is pricy. I second Kyle, betting it's the oil because you can not use many auto oils. You may want to go back and look at some of the precious discussions, or get the Rotella T.

Which oil did you use? If the clutch were slipping due to standard car oil being used that would make shifting difficult. -Kyle On Mon, Apr 2, 2012 at 8:07 AM, Bryan Gibson <[email protected]> wrote: New rider with an '85 Nighthawk CB650SC. I bought the bike in February from a guy that claims to have taken the bike out West just before he decided to sell it and after getting to take it out 3 times, the transmission seems to be shot. He claimed to have done routine maintenance and was nice enough to change fluids except for oil. So I went ahead and did so using recommended oil/filter. The last day I rode it, I noticed that the bike started having trouble downshifting lower than 3rd and when I was lucky enough to get back down to 1st at a stop, I couldn't upshift past 3rd. The clutch seemed loose, too. I checked the brake fluid level and noticed on the clutch side that it was low and full of sediment. I went ahead and changed the brake fluid (using recommended fluid) and the clutch was back to normal but I was unable to get any gears past 2nd (on center stand with the engine off). After another 10-15 min of sitting, I now only have first and neutral. I guess my first question (being a noob) should be, is it bad to shift gears without the engine running? When I shift gears, the "good" gears click in, but once I try to go higher, it just makes a solid "clunk" like it does if you were to try to upshift past OD. Does this sound like a shift fork, bad gear or does the entire tranny need replaced??? I'd appreciate any help as I'm itching to get back to riding. (I ordered an OEM manual that isn't here yet and can work on simple things but I'm afraid rebuilding anything is above my pay grade.) -- You received this message because you are subscribed to the Google Groups "Nighthawk Motorcycle Lovers!" group.
