Hello friends of the forum, I am Ariel from Argentina and I am in contact to see if any of you have information about a cut in the march of the Moki 250 cc due to high temperatures or lack of ventilation in cylinders or ignition, what can I say is that the latter I have installed just behind one of the cylinders, removed about 8 inches back. On the side of the ventilation of the same, I think they are with enough air flow both input and output, the model is a Gee Bee r3 of 128 inches in span, I hope someone can tell me something about it, thank you very much, greetings to all.-
