If the yellow mark are flush with top of the cylinder head OUTWARD it's TDC overlap, not fireing. If they point towards each other then is TDC fireing.

@@Mcdoktor the point of this video was that i assumed that tdc is always just tdc, and that at any given tdc, the teeth on the timing shaft would be in the same place. not the dot or a specific tooth, but the teeth in general. as such, you could just set the engine at tdc using the locking tool, line up the cam dots at the inside or outside as they were when you pulled it apart (it's a while since i did this, i forget the specifics and i;'m not going to rewatch it to answer this), and it would all be correct. i was wrong. the teeth on the timing shaft are in a different place tdc overlap vs tdc firing, by about half a tooth. so fitting belts at one tdc will have the cams in the right place, but fitting them at the next tdc the cams will be half a tooth off. this was a valve adjustment - cams out, engine rotated who knows how many times using the piston to hold the valves up. so i was half right-ish, and i'd say using this method is still faster than the factory confusion. you lock the crank and it's either the right tdc or one crank rotation away from the right tdc. or just not rotate the crank past the tdc required to hold the valves up as someone else suggested. i was experimenting and learning. thought it might help some people if they really screwed it up or had disappeared up their own arses in confusion, and to de-mystify it a little.

Hi Brad, I adjusted all my MTS1200 closer shims as they were all too loose. They now are in spec ranging from 0.05mm to 0.10mm but I'm now getting a light tapping sound I can hear at idle that wasn't there before. Any ideas what might cause that? My only suspision is where I have 0.05mm on the right closer, 0.10mm on the left closer, on the same cam, and the lack of synchronisation between them causes the tap.

your suspicion sounds like rubbish to me, but you could always redo it and make them the same to rule it out. really no idea, you could be right. but why would it be louder with less clearance? i don't see that the closers would make noise, but i guess there would be something as the opening rocker pushes the closing rocker into the closing lobe as it accelerates the valve open. softened by the closing spring? not sure. surely it'd be less noise than a loose closer though?

Thanks for this Brad. You are lucky to have those rocker arm holding tools. What is your approach when the closing shims won't drop down to expose the collets, and when the collets are really stuck in the valve stem? My 72000km Multistrada has had stuck closing shims and collets on all of the vertical valves. Had to use a hammer and socket to bash the closing shims down and then a hammer and screwdriver to get the collets out. Bit worried I will damage the valve seal if not careful.
@bradthebikeboy
@bradthebikeboy 2 ай бұрын
i use a 3/8 extension, but you need to be mindful that the valve is sitting on the top of the piston, and you'll bend it if you hit the shim too hard. just tappy tappy tappy for as long as it takes. the collets can be a real pita, i use a little screwdriver or pick. the biggest concern there is losing them as they fly away. you can have the shim down a touch, but tstill covering them somewhat and get a pick in between the ends of the collets. no magic method though. generally, the stuck collets is a real 1198 thing ime.

Can the valve clearances be checked (not adjusted, just checked) with the engine on the bike and the belts on? I'm looking at a 796 with 12k miles and the owner doesn't know if the valves has been adjusted, but he did just put on brand new belts, so I don't really want to mess with the belts if I don't have to. Also what is an acceptable clearance for both openers and closers?
