The springs loaded gears are there to make the camshaft revolution a smooth transition and help keep down the noise caused by chain slap. Whether or not the springs are preloaded shouldn't make any difference in the clearances.



Exactly right about your valve clearances, basically the spring loaded gears maintain zero lash and cuts wear and valve train noise down immensely and has just a little give in RPM changes, follows the very wise adage, "that the tree must bend a little with the wind or it will break" kudos to Triumph engineering, BTW, they didn't invent this, but they wisely did implement it in their design. If your engine is running good, than pulling your right side cover is probably unnecessary and will just have you awaiting a new gasket, it was a two week wait for me last time I ordered a couple from B.Bandit.
