Well had my first outing at Lardner Park in Warragul on the weekend, it didn't go too bad,was running first in class until a crash in the last leg, ended-up third overall.
Our race was combined with the 'Pre 90' class, first race the KX was first home outright, beating a few water-cooled CR500's in the 'Pre 90' class! Took a second overall in the second race too, with many 'Pre 90' bikes behind.
Next on the list of things to improve~ The wide ratio gearbox (lower first & second) does not work on the mx track, now have a KX420 gearbox coming for it. I'll have to make a pipe for the bike; it had no top-end power, that combined with a wide-ratio box caused the bike to bog-down on the up-shifts if I didn't rev it into the gutless top-end. I'll try it with the noise-deadening mesh ripped-out to see if that helps, failing that it may be a trip to GMC is on the cards.
