The odo is at 20,000 and I am setting the valve lash Guess fracking what I dropped the valve shim into the engine, I THOUGHT that I had the chain tunnel blocked up, NOPE I missed the relief that allows oil to run down the tunnel by the exhaust valves on the front head a long and careful search did not find it on the table or in the head an hour looking with a mirror and a strong light first any suggestions for extracting the shim with out major tear down? I am strongly considering going frame off to deal with this can it be done engine rotated? IF not May I borrow the following items from some one 1. engine stand 2. crank locking tool 3 cam locking tool in that the right side may have to come down what else is needed I have the fsm this is the first post I can send a check to cover the tools if you like, I am well known oon the board and will pay freight both ways for the tools and replace them if damaged any suggestions are welcome I will likely do all future valve / engine services frame off Also I would like to borrow a fork spring compressor tool ( I need to change the oil in my forks ) same applies as above .. I knew this could happen I Tried to block the tunnel but missed the spot by the timing gears in front Comments / suggestions welcome TIA Jim * | ||

OH BTW on another thread some one mentioned getting a kit other than hot cams, part of why this misery is happening is that the Hot cams kit did not have a needed shim I also noted about .0003 variation in the shims.... sadly the valves were in spec on the tight end of spec in theory I could have buttoned it up and been ok BAAH!!! | ||

front or rear? pull the frame,swingarm and try rolling the engine the direction that you think the shim fell into. might get lucky. could also attempt to magnet it out with one of those small extendable magnets from the auto parts store. best luck! tim | ||

I have a magnet tool, I had to magnetize a long slender screw driver I don't know where exactly it fell but it came up on one attempt so I am going to stuff the tunnel back full and get on with it, Thanks for the suggestion Tim Christmas and birthday at the same time!  | ||

Congrats! Sometimes you just have to take a breather. | ||

Yeah sometimes you just have to take a step back. If I remember correctly, a member posted his Dropped Shim Saga with photos of the hand made tools he created to find it. Magnet with a string, etc. You were plenty lucky it came out on first try. Button it up if it's in spec and ride. It's all good. | ||

one intake and one exhaust front head both right side are +.001 over the max ie, 1 exhaust at 0.014 one intake at 0.010 vs 0.013 ex and 0.009 in I don't expect any issues, as the front head seems to be getting tighter buttoned up new plugs heat shield going on thanks all.... | ||

Just starting my first valve check and this is my nightmare. The last story of a dropped shim sounded like it took two days and an array of scopes and magnets to extricate it. That is exactly the kind of thing I am likely to do. | ||

Freight pack the chain towers and plug holes with paper towels don't skimp, I missed an area at the front of the front head and around the timing gear that let the shim drop in to the chain area good tweezers ( magnetize them if possible ) take your time the actual job is pretty simple rotation or pulling the frame is a pain .... |
