    Hi Folks,

    I am doing a valve check on two bikes. 1995 R100R and 1995 R100GS PD. They both have oil coolers. On my R90/6, I just pull the valve covers and turn the rear wheel to move the flywheel to get to TDC. However, on the '95's, the manual says to pull front engine cover off so I can get to TDC from the front.

    Questions:

    Removing the front cover seems to be a pain because the oil cooler is in the way. Cover won't slip down behind the oil cooler. Do I need to remove the oil cooler?

    Can't I just use the same method as my R90/6? Does the flywheel have markings on it for TDC, etc.?

    If I have to remove the front cover, do I need to unhook the battery so the front cover doesn't short anything out on the front of the motor?

    Thanks for your help...

    You should be able to use your same procedure from the /6 on the 95s, markings are there on the flywheel as I have a 95GS and have always done it this way. Putting it in 5th also helps if you aren't doing that yet, some choose to pull the plugs to make it even easier to rotate the engine but I've never had to.

    Also, you should definitely disconnect the battery cable before removing any of the engine covers (when you actually need to do this), just in case.

    These are either/or procedures.

    Wheel bumping with plugs out is quick and dirty, and safe.

    Pulling the alternator cover is tedious and you *could* short the diode board this way if you don't disconnect the battery. Plus, your oil cooler is in the way.

    At one point I read that the alternator bolt method is not preferred, but I forget why.

    I always use the wheel bump.

    Wheel bump fer me. Less stuff to remove, for one thing. I also don't like rotating the engine with that fairly shallow 6mm socket head, it's just not that substantial seeing as you have to reach pretty far and around a corner while you watch the timing marks.

    Thanks for the replies, guys.

    In regards to using the allen wrench, I had heard some talk on the forums about snapping off the shaft while trying to rotate the engine...

    I like rotating the wheel, yes in 5th gear, to get to TDC. Seems the easiest way.
