Has anyone removed the front piston without having to split the cases?

I am rebuiding an engine w/ a sucked valve. Engine is out of the bike. Need to take out the front piston. I took the oil pan off and I can (almost) get to the piston, but it just really tight.

Anyone done this witout splitting the cases?... I just hate to.....
or should I just be a man and split it? I'm not a expert mechanic, just a tinkerer- so keeping it simple would be appreciated.

Thanks in advance.

 

If the engine is already out you should certainly split the cases. It's not that tough and will actually save you time in the long run. The front cylinder rod/piston could possibly be removed without splitting the cases, but the extra effort required is not worth the time savings.

Don't forget that you should run a hone through the cylinder before installing a new piston and rings. This would be VERY difficult to do without getting particles all over the crank, which is bad. Do yourself a favor and split the cases.

 

+1 for splitting them. I think you'll be happy that you did in the end.

all the more reason to split them in my opinion. I suppose if someone was a real pro they could do it and understand the ramifications of what corners they are cutting - for myself (strictly a green, learning amateur) I split them to change pistons and was glad I did.

 

Thanks guys.... exactly the input I needed.
