I have a 96 cbr 600 f3. I'm new to this but recently everytime i hit a bump i would lose power. Right after the bump it would be fine. Any ideas?

 

Check your battery connections, one could be slightly loose and jumping off the connection

 

Stop hitting bumps. LOL

but on serious note, like Bladez said check your battery

 

Lose power to what? Electrical flicker, or torque, like out of gas?

 

Like torque. And i bought a brand new battery a couple weeks ago and all the connections are alright. I rode last night and i hit a bump and my buddy said flames shot out of the exhaust.

 

Wow?

1. I would check the plugs? Pull it to see what it tells you? Is the plug installed correctly.
2. I would check the spark coil wire, is it loose? Is it plug in correct sequence. (how does the bike run without hitting bump?)
3. Flames? there maybe a mis-fire...timing issue.
4. If it wasn't the flame, i may check the fuel pump connection.

need more members to jump in on this one....

 

I'm still thinking electrical issue, either a frayed/pinched wire grounding to frame,
frayed/pinched wire intermitent connection, loose wire going into a connector and/or
loose connection/connector. Just because the wiring "looks" good, doesn't mean it IS
good. physically dis-connect each connector, in turn. Look for weak wiring connection,
burnt pins, melted/warped plastic, corrosion on the pins (male and/or female).

If they are good, pack some di-electric grease into the connector, and move on to
the next. If you do that, even if it isn't the source of the problem, you'll have boosted
the health of the harness, anyway. So it won't be like the time was wasted.

Start with the fuel-pump, ICU, and battery mains. Since, if current is interupted,
they might display the funky ignition/carb issues as a symptom.

Also, check for a faulty fuse. Do this by testing the NEW ones for continuity,
and then switching them out for the originals. Inspect the buss,
while you're doing that. Look for the usual suspects of heat sign,
i.e. the symptoms of a bad connection.

Besides being good maintenance for the bike, it will eliminate the most inexpensive
cure, BEFORE you move on to the more costly-type possibilities.

+1 Ern & i'm just throwing in any chances...check the

It was one of the spark plug wires. I changed them out and it stopped. Thanks for all the replies guys. I'm new to this whole bike thing. I bought it as a starter bike and I've spent more time fixing it than riding it. I rode it today and when ever I let go of the clutch while it was in nutral a rumbling sound started but when I pulled the clutch in it stopped. I have no idea

 

My understanding is a slight 'rumble' isn't that unusual. If it starts to increase in
volume, it may become a cause for concern. If the clutch is operating normally,
I would just put this in the "observe/monitor but not worry" catagory.

Welcome to the "whole bike thing", unless you've got fist-fulls of money, wrenching
is an integral part of bike ownership. IMO, it's half the fun. But I'm a little wierd that
way. lol

Don't despair, though. Once you've worked your way through the inital 'kinks' of
owning an older/used bike, the shop time tapers off. You'll start spending more of
your time in the saddle and less in the garage. (Unless you get bitten by the
wrenching/modding bug, then all bets are off!)
