Trials Australia Forums

I joined this forum, to follow your builds. :)

that kdx stuff (and all of it really) is fantastic.

thank you for documenting your trials and experiments :)

Thanks Kyel. I'm still around just nothing todo. All maintenance and tweeks

Edit
Actually I'm building a gravel bike for commuting. Way off,topic. If you request I could document it.

I finally get that motor. It's what I wanted, bang like a trials bike down low and sing like an angel up high.
It bla bla blas faster till ignition.
It's all that carburettor below half throttle it acts like a trials size carb.
The volume may be less but the increased crank case preasure makes up for that and at 2/3 revs it ignites.
It's not how much it gives but that is gives so much.

The way it lights shows its at full power. Open the power valve earlier for more.


My friend on a Ktm300 says "god that thing's sharp. Yer but so is yours. Not like that it's not "

Never did get to map that.
Went from stock to 15mm. With out ever knowing I would say 5mm is not enough 10mm is better and 15 is close. 20 may be it.
Tuned it the normal way:
Make a prediction adjust Watch.
It achieved what I wanted so never touched it since first test to the max setting first to see what it does.

Seems I have been hear before. Two washers is standard I think.


Clean enough seems good.


So if it's that. All it dose is put preasure on the power valve shaft to slow its opening.

It's a bit hard to get to so if I


Then tweek it up till it stops rocking


I'm done


That looks like one more washer.


Or just remove it all togeather.


Peice of paper in there to check clearance and alls good.
See what happens.

This is what boredom looks like. Still haven't tested the last mod. There is something around the corner but not there yet.


Thought I'd make my own candel.


Had some candles so took there wicks out.


I'm a messy gardener.


Ok I see where I went wrong. Melt the face off and start again.

Nice.
Now it's free to come in when it wants its a grey zone around 5000. Pretty constant patten. Prone to flightlyness on those loose rough rock washed out steep hills. The easiest way is to slip the clutch and paddle your way up. One loose rock around 5000 and its straight to 11.
