Wow! Didn't realize I'm dealing with someone that thinks you can put Honda parts in a KTM! Even a good parts replacer knows you can't do that. An OEM KTM piston is $409, not $160. I wish it was, but it's not. While it's apart I am going to clean the head and vavles up. Also going to change the oil and filters. Service the air filter. Thought I might also put some metric bolts back in places that have standard bolts to make it right. A new spark plug too since the one in it has so much carbon on it, you can barely see the electrode. Also when I give an ESTIMATE, I will add some for those little miscellanous things that always pop up. Anyone that does service work on dirt bikes knows there is always something. If when I finish the job the bill is less than the estimate, that's a good thing. The customer will appreciate that. If I hand him a bill that's more, well that's never good. Just trying to do good work that's fair for everyone. The actual owner of the bike is ok with the estimate and wants me to repair the bike. Guess I'll quit wasting my time and get to work.
