I am posting this for a friend of mine who was just willed and IS, the bike has a few issues but nothing major and he want to pull the heads and check the pistons and cylinders so his question is can you pull the pistons by removing the keyed rings or do you have to split the case? Thanks you your help.

You MUST split the cases.
Not a job to do without a real need.

If there are no major issues, there is no reason to pull pistons unless it has 400,000 miles on it.

Why would you do something like that? Was the bike submerged under water or ridden into a mud bog and left? These engines are almost bullet proof, and should run. Clean the bike up, clean the carbs, and ride it. Much else would be a waste of money and time cooldude

Splitting the case is a real job, even more so putting it back together. Why even remove the heads, Just do a compression test if worried and be done with it.
If it ain't broke, keep fixing it till it is.

Have him/her get off their butt and get in here and let us know what kind of problems ..could be a simple as a pinched vent hose, bad petcock, etc...
A good description of the issue will lead to better help figuring it out.

Pour some gasoline additive in the tank and ride it.

Naturally it would be best to drain all the old gasoline out from the carburetors and the tank first.

He ought to know how to do that!
