Clausiam, yes it is tapered but just us some IIRC 1/8" clear vinyl. Split it down the middle and then wrap it around the inside of the lap timer holder. This will act as a liner and fill the gap as the ignition ring is smaller than 50mm. Once clamped down tight and center on the flat part of the ring it will not go anywhere.
Another problem with sliding the fork tubes out is it will throw off your front end. If you read the manual stock position for the front forks is about flush. If you change that it can have negative effects. I lowered my forks a little at one time and it made the bike dive a little and turn slower. Now that I have the set where they feel good on the track I have not room to mount them on top of the triple.
