Hi everyone! This is my first post
I have been lurking in the shadows for quite some time so i figured i should pop in and show my appreciation to the site. This site is awesome!! Gobs of usefull info to be gained here. I'm the proud owner of a '93 K5 and have had it about 3 years now. It is very clean and in great condition. Bike starts in 1 or 2 kicks, cold or hot and runs very crisp from bottom to top end. Runs strong and pulls like a freight train. It is my only bike so it has been ridden alot since i bought it. So here is my question. How long should i be able to go before i need to rebuild the engine? I clean the air filter every couple rides and last time i checked compression it was almost 170 psi. I'm pretty sure it has a stock piston but not positive as I have never had it apart, but i looked up the exhaust port and it looks to be a cast piston(not sure though, how do you tell cast from forged?). I want to do the top end but money is very tight right now and is probably going to be that way for a while. Should it be ok as long as it maintains good compression? I've heard of cast pistons blowing apart and thats what worries me. Any input is greatly appreciated. Here is my setup in case anyone is wondering.

P.S. sorry if this topic has already been covered but i don't remember ever reading it. Thanks in advance
