Like I told before. I have already made these modifications.
I make 40 plates like supertrapp and put them inside the Cobra
First I made 6 holes around the tube, them I made the same holes in 40 steel
plate of 1,2 mm tikeness.
After that I start to make the Cobra works like a trapp.
The big difference is to change the resistance of the gases in each tube.
If it is true the MAX cylinder 1 and 3 have more difficulty about gas now I
cam make them work more open the cylinder 2 and 4 more close or the
opposite.
I don't now yet if it is possible to increase the power. But the bike is
wonderful and works better the original scape. The Cobra lighters 10 kilos.
