I have my engine in the shop to install a new trued & welded crank,bore,and pistons.
My question is, while my jugs are in the shop i want to clean my coolhead,Is there a special cleaner for this or can i just clean it soap and water?It has a little bit of stuff inside the groove where the o-rings sit in,its kind of hard to get it out with just a dry rag ,so guys i need a little help on this. THANKS FOR YOUR HELP.
