Good setting cylender vith booster

[Pwe]

I want know the setting for a cylinder with 2 boosters.
NOw I have a bing 20mm with jet 35 mm and 78 mm filter in order jamarcol fuego and ignition ducati cdi top perf red ignition timing 2.5 mm before PMH.
Is it right ?

I think , your exhaust is the bottleneck in your setup.
Nice exhaust for about 5 hp , try a better one.
And how about your cilinderhead , is it modified already ?

I dont know your red cdi , but 2.5mm seems a little bit to early for me. Try 1.

for the size of the main jet : keep an eye on your spark plug !

It is a special cdi with a special timing inside a low RPM you have 19dg and then at 9000tmm you have 12 dg .normally it is for a minarelli engine with a ducati ignition but it is for a 39 mm and Kreidler have 39.7 mm so you need to have 2.5 / 2.7 mm for a good timing .
Try to found on google «  cdi top perf rouge «  you will anderstant .
I have try with a origine silencer but with the jamarcol fuego the engine take more rpm and I have try a 80 jet but it s not good I need to take off air cleaner

When you control the advance with a stromboscopique light you have only 1.5 mm a low rpm .
But if you want to have this you need to have 2.5 mm
On a mirarelli engine with 39 mmm course the timing is 1.2 mm but with a Kreidler it sis not the same thing because the course is 39.7 mm so you need to put 1.2 +o.7 about 2 mm at the beginning .
In reality you finish by 2.5 2.7 mm timing because you need to have 0.9 in high RPM

I have try also a MVT ignition system.It is a good system for powerful but you loose torque in low rpm and the gear box make more noize in neutral gear . With the top perf système you win torque and in high RPM you have the same powerful as a mvt system ignition .The curves is good you begin with 1.5 mm and you finish with 0.9 mm in high rpm at 10000/11000 with a bing 20 mm in order
