[QUOTE="Silent, post: 1137665, member: 4841"] Well, I got the engine out of the bike, took a LOT longer than an hour lol. Complete motorectomy [IMG]https://i179.photobucket.com/albums/w318/NAA_Silent/FJR/DSC_5208_zps7e9f873b.jpg[/IMG] Royal pain doing that solo I might add. I pulled the head, and after stripping 3 12mm sockets, 2 of which were 6 point, I wound up drilling one of the heads off of one of the bolts. Thing fought me to the end, but I won. Ok, now to the nitty gritty. This is what happens if your timing is off by more than 1 tooth and you put the cam in. Tightening the cam caps put enough force on the valves to push them into the piston. No damage to the piston, just 2 bent valves on #1. Yes, I did try and turn the motor over by hand, and it was frozen. Pulled the cam but the damage was done. [IMG]https://i179.photobucket.com/albums/w318/NAA_Silent/FJR/DSC_5210_zpsd57e3eaf.jpg[/IMG] Lots of carbon build up on the pistons and head. And yes, those are brand new plugs. [/QUOTE]
