Swapping valve types

[Webmasta]

So...i have a 91 katana 600 that i blew second gear in a while back, ended up buying a new used engine and they said it was a 91 katana 600 engine. I went to do a valve adjustment and it was shim type so i looked up the number on the engine and its a 92. Is there anyway i could take the valves off my old engine and put it on the new one so i dont have to deal with the shims?

Easiest thing to do is swap heads as long as the cam chains are the same type. I Dont know if you can just swap in the cams and rockers.

Just run it as shim, you may have to adjust 10-20,000 mile from the adjustment point. Not a big deal

I always thought all Katanas were shim type. Hm. Either way, stick with the shim type.

First thing I would look at is if the sprockets on the cams are different between the types. If they are the same, I can't think of another reason why swapping heads would not work. You may need to answer this question for us.

Meh, not a big deal to do an adjustment. It takes me about 20 minutes to check/adjust them all at this point. Takes longer to remove the plastics/tank/cover, but even that takes only ~40 mins.
Granted, first time took significantly longer but once you get it the first time, it's easy afterwards.

I just dont want to waste money on shims...im kinda cheap lol

And i only want to do this because my engine has a wicked ratlle and sounds terrible. Not sure if its the chain but i tried resetting the cct and didnt help.

Cct springs do fail. They are cheap and easy to change.

I replaced the one on my 1100, which only had ~12000 miles on it. The spring was horribly out of spec. Side by side with the new spring, there was at least a full centimeter difference.
If you can pull the carbs, you're 90% of the way to replacing the spring.

Good thing i have a broken engine that has a few good things on it, im going to pull them both out to compare

Yup, almost had to pull the alternator too cause i thought i only had a deep socket...its funny how i knew absolutely nothing about bikes up until May of this year because I decided to go from first to second with max rpm

Ill take a look at it today if the cct spring isnt a problem i can fix today

They started using shims in 92, i wonder why they had to make things a little more difficult...

Might try it today

So after i swapped the springs on the cct there was no difference...before i try swapping the heads is there anything else i can try to get rid of this god awful engine rattle?

You'll need a new gasket between the cylinders and the head if you swap the heads.
Some of the bolts that join them are likely going to be problematic. Take your time, don't rush it. Always seems to help
