So after leaving you with you're genitalia in you're hands, we can continue.
The KTM620 front i bought have thick axle.the original KTM bearing can't seat in the steering head because it's size.so i used XR600/650 bearing.
to do so,i had to machine the axle to fit the bearing.
i took off about 3mm thickness.
after doing so, i stumbled another problem-there was a big gap between the axle and the upper triangle.
So i machined a spacer to fill this gap.
Worked pretty good.
I hope it will stay strong...
Starting to get a gooood shape...
got myself a 320mm disc.
What is left for me to deal with is the calpier issue.
I need to find a KTM 620 caliper.the adapter i already have.
I'll report later on.
