I have been chasing a 1st Oversize Piston (81.9mm)Part Number 1610558-02 for my 1970 CR400 with no luck. Can anyone put me in the right direction? The only place I could find was Vintage Husky any he has only Standard Size pistons left.
The last Piston had about 10hours of trail riding use and the rear skirts broke off to my delight. Was this a common problem with these delightfully old Huskies?
