Death Rev

[fxnteeth]

So I was thinking my death rev was because I didn't put the needle in the slot in the carb correctly upon reinstallation. I pulled the carb, everything seemed fine. I took to shrouds and seat off just to look and WOW. The black and red wire had melted and had a nice black area on the frame. the plug wire was just spinning to where the internals were making sporadic contact with the ignition. Jesus, I neglect her for a few months and she gets Pis#$%. Almost like a real woman (no offense to the ladies that read this) Oh well. Will get new plug wire, and electricals.

Don't think I have heard if a reason like this for a bike revving out of control but good job figuring it out! Let us know if that fixes it once replaced

[Vealmonkey]

First I heard of that reason. Usually fuel related.

[Dirtcrasher]

Did the over-revving cause that??

I'd make certain that the carb slide or throttle valve is free and that there are no air leaks. Otherwise, it's that electrical deal.....

No worries, plenty of woman are on the "take until I can support myself" wagon :lol:

NOT the lovely ladies from 3WW :D

They all rock!!

Contact, spark, or whatever, without fuel it cant rev. Check your carb and intake over good.

When I saw Death Rev, I immediately thought air leak...

Kinda like when a chainsaws running out of gas, not good.

I lost an engine to "Deth Rev", it turned out to be a air leak. I would defiantly check for one

I had bad death rev a few times on my 500r because of debris clogging the pilot jet.

I lost an engine to "Deth Rev", it turned out to be a air leak. I would defiantly check for oneand that's why its called a death rev. The only way to stop it is putting the bike in gear and kill it with the rear brake or cut the air of to the carb. some times the choke will slow it down enough for the kill switch to work.

Usually If the engine is revving and can't be stopped it is because of a lean condition, sucking air, or starving for gas. So if it ever happens again, slam the throttle wide open, and it will shut right down.. Sounds wrong, but it works!! It won't work if your throttle is stuck, but if the throttle is closed, and it's revving out of control, opening the throttle bombards the engine with air, and it will shut right off.

i would have to agree with everyone here.

and my 2 cents.

death rev = lean, sucking air from somewhere. If it was a spark issue it would not lean out and death rev because it would now have more unburnt fuel... and not "death rev". Build a cheap leak down tester! they only cost like 10 bucks to build and will save you a TON of money and guesswork. if you need info on what to get let me know.

air leaks happen. crank seals, base gasket, carb boot, head gasket, reed cage.. blah blah. heat can also make a sealed engine leak. i've thrown a pair of welding gloves on and ripped my pipe and carb off quick to find a leak once. my old (83 250r) is verrrrrry picky. I had a small leak at the exhaust. It has the stupid ring its supposed to seat against and even brand new from the factory that couldn't have sealed very well. once hot the engine would start to pick up and rev slowly and not return to idle. i chased this problem for 3 months! all it took was a new ring and a coating of rtv silicone. done.
