I remember back in the early 70's all of the different dirt bikes. CZ's, Ossa's, Bultacos, Maico's, Can-Am's, just to name a few.
Those were some good times.
Took my son to a mud run when he became bored told him to pick cans and bottles, over the three day event my son made $1200.00. He wanted to buy a dirt bike so we went looking for a basket case and found a Kawasaki KDX 80 with a seized engine that would make a good father /son project.
Piston seized in the cylinder, scored the chrome plating inside the cylinder bore then to top things off a bent connecting rod,
We took the cylinder into Mongose a shop that specialises in small engines, they installed a Wiseco sleeve and supplied the piston and connecting rod from the same manufacture. When we received the reconditioned cylinder we ported and polished the ports also making adjustments to the piston to port deck height at bottom dead centre. before putting the engine back together.
Wisco supplies sleeves and other high performance parts.

My son now had a bike with good performance that could almost keep up to my Can-am we spent many a weekend checking out the various trails and logging roads.
With Wiseco parts you can resurrect any sea-do, cycle or sled engine back to new.
