the bikes we are looking after is the used by John Barton in the IoM TT in 1999, with a 118mph lap in the race this bike is the fastest ever to lap the Isle of Man TT The bike is stone stock, standard in both engine and apart from the careful of the squish and cam timing we performed it set out for the island last May.

It has now 1500 miles of really running, none of your trips to the shops for this We dynoed it ‘as raced’, we got to take it apart. Dyno run 005 the power.

The bike was then stripped for a up , just as we would for a normal bike, that means down with the heads lap the valve seats to remove any and take away any dents in the set We have noticed that the valve seats on the horizontal take the biggest battering. As we the head we measure all the present sizes and then measure the

In this bike there six valves where the ‘Half that retain the valve broken. This happens on that are revved a lot, the of the closing shim (which over the half ring assembled) stops it being a big nevertheless it is something you keep an eye on and you change the broken rings time you service the bike.

To keep this in perspective our racer only broke rings at very fast Silverstone and Thruxton for example.

The belts were understandably a loose but that was to be expected. The was a little stretched and was replaced. our experiences with the 996Bip we stripped, checked and reassembled the and clutch.

The dyno charts really their own story, Dyno run 005 is the as curve, Dynorun010 is the version the reset of the clearances, a lap in of the valve and a thorough going over. The curve is the output after we had the mixture on the FIM Eprom with improvements in Horsepower and torque a couple of zones slightly out.
