But your segments are straight, Uncle Lozza.
...........not even with your fattest maggot and your shiny new gold plated hook
Less bends the better,
What's that Lozza ?
It's a Cagiva Mito frame with a KTM 380 engine
Yes straight is best but as Yamaha found out 2 straight with 2 curved made the top cylinders detonate, so they added 'deto buttons' to make them as inefficient as the lower pipes. However Aprilia RSW 125 had a dead straight rear under seat pipe, with the change to the RSA 125 with an under pipe , it made no difference to detonation or HP. Such is the two stroke.
Hydroformed pipes never make the same hp as an equaly dimensioned cone pipe.
