I ended up with an 05 recently for $500. It was all there, just needed valves adjusted so the PO claimed. Yeah, right. Anyhow, it wasn't locked up, so I paid the fella and took it home. After taking off the valve cover, It was obvious that it had been apart and buttoned back up due to an idiot with tools. He broke the cam wheel trying to pry the chain off, rather than releasing the acct and sliding the bearing over for sufficient slack. But he was right about the valves as the right intake was zero clearance. I found a new take-out cam from an 06 for $50. I got a ss valve & spring set, lapped them in, and put it all together with new gaskets and a cam chain. I know, I should have put a new piston in, but it actually looked really good as did the cylinder. I thought I'd chance it. I've got exhaust valves at .010 and intakes at .005 now. Cam lobes are facing the rear and all timing marks line up. I've got fuel, spark (new plug), and 65 psi of compression (throttle open, decompressor intact). It won't even try to start. I took the valve cover off again & checked clearances, they're good. I'm not sure what to look for at this point. Any help would be appreciated. Does it matter if the crank is on the correct stroke? I don't see how as the timing is set by the cam position.
