Crap, I thought if I spread my threads around that would throw you off the scent   ::)

I'm trying to work out how close what I bought is to a YZ250C.  The gearbox was the last thing I was worried about.  That seems Ok going by what Geoff said so, it should be all good from here  ::)

Only very rough plans for CD at the moment, but I've been to every one since CD5 where I met you, YZHilly, Vandy and a whole heap of other top blokes from this forum, so I can't start missing them now.  YOUR mates Vandy and Mainline are a bit undecided as to what they are doing ::)
If I go via Brisbane it adds 6 hours to my trip.  I was going to meet up with the boys in Brissie, but may have to change that to Goondoowindi (sp?)
There were thoughts of bringing one car down with one bike each but not sure about that.  By then we will each have more than enough bikes to fill a trailer each  :-\  Maybe we should hire a Pantec  ;D ;D

Still all up in the air  :-\

A couple of rusty tips on gears / wheels, but I haven't had a really close look yet.
