I'm more than happy to help... I've rebuilt more than my share of honda engines (used to race Crx's, road, auto-x, and drag and would build frankenstien engines for them before I got the bike) I however, don't believe in sugar coating and will call it as I see it.
He needs to ensure he doesn't turn the bike over anymore, tear it down and break out a micrometer. I can almost guarantee at least one if not more of his rods end bearings spun from oil starvation and the crank and rod end are now an egg shape from beating back and forth. If you stop running the engine at the first sign of knocking you can at least have the possibility of saving the crank by having it turned it if you don't score it too bad. I've seen it and dealt with it.
The other possible cause being the wrist pins is just letting the piston bash back and forth with every revolution, scoring it deeper and deeper, so rather than just honing the cylinder wall for one piston and re ringing one piston, you have to bore out every cyl. get new pistons, rings and ect.
So my advice to help is tear it down and look to see what damage has been done and go from there.
I didn't come on here asking for help from you Jeef ............ if you understood what the word "philanthropist" meant you wouldn't start off a comment by calling someone you don't know a moron.
Also why do you want to drag my career into this, i work on stuff that is a little bit more complex then your D-series/B-series/LSVTEC/mini-me bullshit you raced around a mall parking.
You said i ran the bike with no oil, which never happened. I pulled the bike off the trailer in my drive way, fired it up. Filmed it as a reference, so i had something to show people. And within an afternoon it was out of the bike on a bench getting checked over.
The problem with putting videos in threads is idiots skip the words and explanations and go right for the video. Then start running there mouth with no idea what they are talking about. Maybe instead on "calling it as you see it", you should try and "call it as a you read it".
RD.....thanks for the kind words,and and info. And its like you said about the "bladeforum" mods, Karma can can be a bitch.
