Dropped bike, strange behavior, weird noises

I was riding today when I stopped at a local store about 3 miles away from my house. When I stopped, I tried to kick the stand down but my foot got caught or something and the bike started to lean over. I've never dropped it before and I caught it before it hit the ground. I was holding it up, but it was way too far over to pull back up so I tried as gently as I could to lay it down.

Everything was very gentle and I pulled the bike back up and I couldn't see any scratches or anything. As far as dropping it goes, it seems like it went pretty well. So, without thinking of the condition of the engine I went in and bought a few pieces of hardware I needed and came back out. But when I tried to start the bike again it was really tring hard but wouldn't turn over or whatever. Eventually I could feel it "catching" so I gave it some gas and it started well but when I let off it just died again. So I put on the choke and started it again but the same thing was happening so I had to keep giving it some throttle until after about 10 seconds it started to warm or something and caught again.

Everything seemed OK when I headed back home except for it starting to rain but when I slowed to a stop light, I could hear that the bike was acting like the clutch wasn't in even though the lever was fully depressed (the actual lever didn't touch the ground when I dropped it). It died when I came to a stop. I started it up again with the same technique as at the store but now it sounded all gutteral and low like a big cruiser! I looked and all the parts were still there but it just sounded like there was no muffling going on whatsoever. When I took off it felt extremely underpowered and I had to rev it pretty high just to take off.

So now I'm home, soaking wet, with a sore back and a weird bike... Anybody know what's wrong?

Thanks in advance

I think it was flooded at first. As for the clutch. You may have twisted the leaver and or bar and pulled the cable tight forcing the clutch to partly disengage.
Try it again in a few hours to see if it runs better. Check that you have just a little free play at the clutch lever also.
I think it was just flooded, and ya check that clutch cable to make sure its not pulled tight, there should be a little bit of slack in the cable.

Ok yeah I tried that in 1st gear and it very obviously wants to move. So this pretty embarrassing, I really know nothing about mechanics and I don't know how to adjust the cable or anything so I'll have a buddy check it out. If anyone can tell me how to do anything I'd appreciate it. The bike's a CB700SC. I'll check the shop manual. Thanks
There is a knob up near the clutch lever. When you turn that it will adjust the clutch cable. Now do you have a cable, or hydrolic clutch is the question?

cb 700.... it its not cable actuated i'll be a monkeys uncle.
AH ha! May not be totally true JK.

My older bro's ex bike...a 1983 night hawk (cb650sc) Had a hydraulic clutch, and front brake. So I know the CB series did have hydraulic back then. That [email protected] bike even had a digital gas gauge, and gear indicator! A freakin 83!!!

guess my chances of monkey uncledom has improved- :lol:
cycledesign said:
Yeah, I checked it has a hydraulic clutch. So, still don't know how to adjust it or if I should adjust it...

Anyway yeah it's a great bike and I love the features for an '84. The fuel gauge isn't digital but it has the digital gear indicator.
man o man am I good or what! :lol:

As far as adjusting that hydraulic clutch, I'm not sure you can. The only thing I can think of is check the fluid in the resivoir. Possibably replace the fluid. Now the one that may really fix the problem, that I'm not totally sure on is bleed the pressure in the clutch line. Since it is hydraulic I assume it almost works like a hydraulic brake. You may have air in the clutch line. :2cents: Look into that procedure and let me know what you find out.
can there be a air bubble in the line?
