My wife likes a bit of critical rod angle, while my 701 likes a good flogging. Few.

On the power stroke in a 2-stroke, the force is against the rear cylinder wall. On case-reed cylinders there is much piston support, on cylinder-reed or piston port cylinders it get to be much less. In the cylinders I machine, the intake side is often worn much more, right where the ring gaps are too.

Happy 4th!!! God bless America!!!

These KTM/Husky/Gas Gas 250 and 300 two strokes have 125 mm long connecting rod and 72 mm stroke so rod/stroke ratio is 1.736:1. If the motor is pushed for high rpm for a long period of time it definitely will load cylinder walls.

Very neet info! If you understand or are at least aware of the true principles of mechanics it makes you a better geek... / wrencher
