Hi, I have been lurking on this site for the last couple months learning.
I have been into bikes for over 20 years but just picked up a project quad.
The quad is a 250r with a 350x motor in it.
The motor is apart and I am in the process of rebuilding it.
I am trying to find out if this thing is on the original bore or if it is over.
The piston has the markings of HA5 on the top. plus it has HF-1 and HA5 casted in the side.
It also has an ink stamp of 25 on the side.
Any help would be greatful.
Thanks, Ken

best thing to do is get a set of calibers out an measure the diameter of the piston
