new cyclone 3000 w mid-drive kit?

[pwd]

Here is some footage of the my "wobble" or run out.

I am going to guess the problem is more likely the cast and machined CRANK vs the BB cartridge, BUT see if you can measure the run out of the BB cartridge spindle.

I have received some new ISIS crank arms and would like to report that the wobble / runout of the chainring is almost perfect now. Seems that your guess was correct Pablo. I missed the opportunity to purchase the ones you had for sale on eBay. I ordered some Jitsie brand trials cranks that were almost identical to the Cyclone ones.
