The gearing was well out, having to use 1st out of the Esses, no where
near peak revs down the straight, unable to pull 4th out of Riches.
The next practice (timed) session for the Moto60 was not long after and so
we decided to leave alone. A slightly more enthusiastic session saw lap
times fall to 1:13.7 after around 10 laps but the gearing was still having
a negative affect through the Esses and corner speeds throughtout was less
than usual (contributed partly by cumbersom powerbikes/600s etc getting in
the way - hmm, a tick on the 'against' side of the 'shall I run powerbikes
in 08' list). Even so, the session was worthwhile and a substantial
reduction in lap times was expected in following sessions.
Discussing gearing options made me realise that maybe it had been a
mistake not to remove the gearbox and find out what ratios were inside
(the only part of the engine touched this year since received from the
States is pistons/rings!).

I felt that a change to one tooth extra at the rear wouldn't be sufficient
to enable drive out of the esses, but due to plent of pending track time
we gave it a go. We decided to try different (richer) jetting and also
fitted an old pair of spun slicks to get through the next few sessions
(hmm, was this a good idea?). The first GP250/600 race was the next
opportunity to find out and was first after the lunch break. I was
impressed with the New Era organisation who split the grid with 250s
first. It was quickly evident that the gearing wasn't correct for the exit
from the Esses and throttle response was slightly hesitent but this was
just the warm up lap so once up to pace maybe all will be ok? A good start
saw an open track ahead (first time since 2003) and some good track time
pending. Riches didn't go too well - 4th gear didn't pull so had to
knock it into 3rd.
