I don't remember anymore. I always used the "racing" and was told that it is done i a rather thin material which is said to be important for the resonance of the waves...anyway - as you can see i really tested a lot of different pipes and the Messico

Actually i know it only the other way round: longer rods for longer time of flushing just like actual KTMs that have a 5mm longer rod... Anyway: i didn't perform such drastic modifications. I concentrated on getting the best performing setup from intake

A shorter stroke doesn't make much sense. Todays bikes have longer rods for longer flush times...lowering cylinders is usually used to gain low-end which on a MX 125 isn't really what you need. Maybe for enduro/woods riding but not on a MX track.

Main diffence between a 4-stroke and a 2-stroke? The pipe, smell and sound So i thought maybe you like to see how my coned pipe got made: Usually i use italian Messico exhausts as they proved to offer best performance with my Mugen engines. I have tried

No-i don't remember. I know how the HPP valves looked like as i still have the ones he modified for my Mugen back then. I also got a drawing with some port measures from Verona. All i know is he drastically altered compression as we needed to use expensive ... more »
