81 CB650 - Deposits on pistons
Posted: Sun Dec 11, 2016 11:00 am
Long-time rider with basic knowledge of engines, attempting my first engine surgery to replace a leaking head gasket on this recently-acquired bike. Everything is going smoothly so far thanks to this forum and YouTube. Upon removal of the head I have found that all 4 pistons have heavy deposits on them, but the spark plugs look good - see photos. Is this a normal level of deposits? Or do I have other issues to address?
I have not ridden this particular bike enough to tell if it burns oil, but there is no obvious heavy smoking from the exhaust...
Thanks in advance for your help!
