The sledge hammer thing... I doubt the bike adjusted itself incorrectly... I would go for the mechanic bwhahaha

You wrote, quote: Every time i have the bike running, and i put it into gear it immediately kicks out. unquote

Trying to understand what is going on seems kind of important. What do you mean by kicks out? Are you talking about jumping out of gear or the bike dying?

BTW, is the bike lurching forward and dying when pushing down on the shift lever to put it into first gear while the cluch lever is squeezed?


that is exactly what is happening. we can move it when it is gear, with the level in. the bike shuts off after jumping forward. i am letting the clutch out slow, but that doesn't matter. tonight i am going to check my compression. eileen is killing me here guys. i just wanna get riding again. taking my friends bikes for a ride is pissing me off. i hate crotch rockets, and cruisers. and i am the only one i know under 35 with a kz. although i keep running into people with kz's in media. damn 250s and 400s. small bikes. what kind of biker gang member am i if my girl don't run. :(

From the description given, I would say the external shift mechanism has some issue. There is a shift drum under your left countersprocket cover. The shift drum is actuated using pawls that work off the shifter. When you press the shifter down, the pawls which are two hooked arms go up and grab a pin on the shift drum. There is a detent mechanism in the upper left corner above the shift drum which has a spring mechanism. If the spring came off or is missing, the detent would slip and you would pop out of gear into neutral. The pawls have a spring that tensions the two arms towards each other. If this spring is stretched or missing, the bike will lurch forward when you put it in gear and might pop out of gear. I suggest you take off the countershaft sprocket cover and ensure the springs mention and the shift pawls are OK.

Assuming, I'm understanding what you're saying your problem is, maybe this will help.

My 750 Turbo lurches and sometimes stalls when I pop it into first gear when it's cold. Common problem with the turbos (more plates in the clutch). Occasionally, when I really really don't want that clunk and lurch, I start the bike with it already in gear. The dragging is hard on the starter but I've got a spare starter (transmission parts are harder to come by). You may want to try that - at least once or twice. If you can get it running and driving, you may be able to at least figure out if it's a clutch or a transmission problem.

One thing I've noticed is that different motor oils affect my sticky clutch differently. If the problem resides in the clutch, it might be that the plates just don't like the oil you're using.

Another point to consider. I think you said your clutch is new - is it an aftermarket clutch? The Barnett I used to have in my bike was the worst piece of crap ever built - I could idle the bike uphill with the clutch disengaged for the first 20 minutes of every ride.

Couple of simple things to chew on before looking too deep. Hope this helps.

i don't know who makes the plates, but i put the clutch back together right. my g-pop wants to get the bike running before we start fiddling around with the lurching problem. where do those tubes on the bottom of the carbs go? we think that they go into the airbox, so that when the bike is running the airflow pulls gas into all four carbs, but we aren't sure. it takes a while to get my bike started, and even then, it'll crap out after a bit if we don't keep throwing gas into it. i really wish someone around here worked on these things

where do those tubes on the bottom of the carbs go?


Those are your overflow hose. They go down between the engine and the swingarm. So, if you carbs overflow the gas will go to the ground and not all over your bike!

problems gone. thankfully she goes into gear now no problem. however, now she just snails along. and i did go through my manual and do the clutch that way. i'm not an idiot, i've been working on engines for five years. i have never worked on a bike engine before.

after work today i am putting on a 650 clutch cable and i am readjusting the clutch, then i'll let yous know how it goes.

Battery charging problems may be traced to several things such as:
1. Loose battery terminals.
2. Green crud on electrical connection terminals.
3. Stator/generator has burned/shorted winding.
4. Rectifier/regulator failing.

I have three websites for stators and regulators/rectifiers:
