Hey guys. Im new here to the forum and was hoping to gain some incite and helpful information from here. I recently picked up an 03 pred 500 that a guy had ordered all the part to redo the top end and never put it back together. Ive got a service manual and am planning to put it back together. This will be my first time doing a rebuild. My first question is that there are a couple of light gouges in top of the cylinder head, the guy said his mechanic says they wont matter but im a little concerned. What can I do for these or should i order a new head? Second question is he was the second owner and the original owner bored it out etc. What kind of issues will i come across with it being bored out and if anyone has any helpful information to make this project easier on my stress levels it would be greatly appreciated. Thanks all!! Cant wait to be ripping it up on my new predator!

Timing chain

One thing I forgot to mention is that the guy said he had this all rebuilt at one point but apparently the person who did it didnt get the timing right and he stretched the timing chain. There is a new timing chain for the quad and ive done some research on the timing for these atvs and have the service manual to do it properly. Anything I should know that may cause this problem again besides doing it right by the service manual specs? Thanks again for any helpful info.
