Hello my name is Andrew and I have gained much information from these pages for which I thank you all very much.
My question is Can the inlet manfold between the carb and the rotary valve be too short??
I race a PVP 251 motor which has a relatively short manifold. It could however be made 5mm shorter quite easily. Would there be an advantage in doing this? Or should I leave it alone.
I have researched these pages but could not find the answer. I aplogise if this topic has been previously covered.
