I see you have a KTM. Compare your GG Kokusan flywheel to your KTM with regard to crank fit (key and taper) and timing. I suspect its the same, I know the 2K-2 stators are, they just need to be remounted to the GG Kokusan backing plate. If the same, you have a bigger KTM part out option.
My KTM's are 4-stroke, the flywheel is inside out, and the taper is too big, i have a friend with a 2-stroker, i will go get his bike and check it out,and post what i find
