hey guys. finally putting my bike back together after a long build and today i checked valve clearances. as i was spinning the nut there is resistance for a bit and then all the sudden spins on its own for about a 1/4 turn. it is preventing me from turning the cam notches towards the outside to check the last exhuast valve. if anyone can help me i would really appreciate it.. here is a video showing what im talking about.
https://www.youtube.com/watch?v=4wIvSYHZEAc&feature=youtu.be (happens twice at end of video)
its normal. you just have to go slow, if you still have the kit that came with the bike. there's a smaller hand tool 17mm, that's what I use.
Put a box end wrench on the crank to turn it. When turning with socket and ratchet you have resistance when you are compressing a valve spring and as you pass the tip of the cam lobe the spring pushes it away from you in direction ratchet freewheels. You can hold it and turn it where you want to without the ratchet. Leave the plugs out too while your turning it to check valves, will make it easier.
I'm not convinced it spinning on it's own is normal. Going from some resistance to almost no resistance is normal as the cam lobes clear the shim but having it spin by itself could indicate a problem with your crank. How much slack is in your cam chain? I'm wondering if the cams are turning by themselves because they lose tension. In that case you're timing is probably totally screwed too.
The video didn't look like it was turning by itself though. If you can take the socket off and it spins by itself from any position you're in in trouble. If it just goes from some resistance to no resistance, that's normal.
few ok good.. i saw other videos and it seems nobody else had it loose resistance and spin for a second. so i started to worry. it keeps slipping like that when i go to point the cam notches outwards.. i absolutely cannot get it to line up it slips past and they wont face out perfect.... and my cam chain is pretty firm.. i would think it fine
hey guys. also one more thing to note that you can see in the video is that sometime is was pretty easy to turn and other times it was pretty stiff.. enough to move the engine as you can see in the video.. that seem normal? just want to make sure before i assemble everything
yeah its normal.. its weird I know, but those springs are pretty strong.
Looks normal to me but I've only done 23 valve checks while putting 180k miles on my 97 and 02 GSs.

thank you a appreciate it alot.. and since you have done so many heres another question for ya.. best way to remove shim without the tool? just use a small flathead through the little notch in the bucket? im searching around now and not finding much.. i want to take it out and suzuki will give me a new one fore just a couple bucks

Look up how to make a tool for it out of a can. You need to depress the bucket to remove the shim.
You did remove the spark plugs, before turning engine and adjusting valves, didn't you ?
Cookie
yes i removed the spark plugs lol
A couple screwdrivers can be used to depress a bucket to remove a shim:

After bucket was depressed with notch turned to an accseable position I would just lift the shim out with a tweezers except for an occasional one that needed a little more urging.

Just chiming in about urging it to come out.
It took me two runs of 30 minutes of prying at a shim to get it to come out. I still have no idea what made it decide to budge. Some of them get REALLY stuck. Just try not to scratch up your cams while you're doing it.
