Stroker Crank for ATC 90

[ATCwithdrawals]

Can anybody tell me what year they made these mod cranks for the 90cc. and who manufactured them?? I know a guy that supposedly has a couple of these NOS still in the box. any idea what they sold for and what they might be worth today??Thanks for any info.

Back in the late 70's and early 80's there were many shops "stroking" 90 and 110 cranks. The old 90 stroke was @45.7mm and the 110 crank was 49.5mm(or there abouts)

There were many stroke lengths available up to and sometimes over 64mm!

Any current crank house should be able to stroke your current crank or Core crank if sent to the vendor.

Good luck with your project.

www.powroll.com still makes a stroker kit for it and a highcomp/bigger bore piston for it.
