Figured this could do with an update.
Dragged the X up to CD5, but it didn't make it to the track. A few things conspired against me: A much-too-low carby float level, a loose choke mech, leaky needle and seat, and a leaky fuel tap.
A few of these things were discovered at CD5, but not all of them....
So I regrouped, and got them all sorted, and then dragged it back up to CRC.
It is a great bike, despite a few (more) teething issues.
In practice, the clutch fell off.... Well, the nut that hold the clutch onto the input shaft of the gearbox fell off, then the clutch didn't work at all. Obviously a problem due to the rushed build....

I wasted the rest of practice sorting that, and then in the first corner of the first race, I got a little bit excited trying to get around Bill C, and dropped it. It was a 'nothing' crash - didn't even stall it - but when I picked it up it was in neutral and the lever was jammed.
So after fart-arseing around with it, I removed the neutral detent mech. "Click", it popped into gear... Weird. So I fished out the ball-bearing and ran the rest of the weekend without neutral, and the gearbox was beautiful.
Not sure that the suspension is right, but I need to spend some time riding (rather than racing) to work out what is needed - plus going from short travel bikes to it, was always going to make the X feel good...
I think the rear spring is too soft for a start.
But DJRacing was right all those months ago when he told me that I was wrong for saying that I could live without an X. It has all of the C's good points (light, flickable, easy to ride etc), with more power and better suspension.
I love it.
