Hello all I Stumbled onto this site looking for parts
and was wondering if i could ask for help. My dad gave me a 78 kz 650 and i have been trying to get in running and have been succesfull seems like all that was wrong with if is the kill switch went bad but anyway when it cranks it runs good but getting it to crank is really hard i was wondering if anyone has any ideas on what i could do to fix this im no mechanic but the bike was givin to me and i think if its not to bad i could fix it
so if anyone has any ideas the would be greatly appreciated thanks

What do you mean getting it to crank? Is the starter turning slowly?

Just a thought, but I had the same problem when I got my 650. I had low compression in the 3rd cyclinder. Weak spark on the first coil, and the jetting wasn't right. If the bike is running well once you get it started, I would check the coils first, then have a compression check done. Compression should be over 65lbs.

I got messing with the bike today and found that the reason it would only start every so often is that the kill switch wires had a short in them. Now i got that it cranks good but if i try to turn the choke off it dies i give it time to warm up the only way i can get it to work right is with the throttle adjustment near the carbs any way of fixing this. I dont mind but i cant crank up and go i have to fiddle with it to get it right first so any help would be appreciated

Welcome Brad to KZR. I find I need to let my bike warm up for a few minutes and even longer on cold days using the choke. I start her with the choke all the way up, then start lowering the chock lever to control the revs, not letting her rev too high.

You may need to give your carbs a good cleaning at some point as well as give your engine a tune up if they haven't been done recently.

Post up a picture of your ride in the photo section as well.

that sounds like a normal thing to me, mine takes a bit for it to warm up and run right, just play with the choke and dont let it rev up too high,
my factory book says compression should be 135-205 lbs,with a 10% rnage between cyl.
