The air filter, the mainspring and the variator are not supplied and remain at your choice! For use, we recommend a clutch pulley which has jaws which engage at a minimum of 6,500/7,500 rpm.
The spark plugs (breaking in and adjustment B9ES then BR10EIX) are not delivered, nor are there any high voltage cables!
Exhaust level, alas, very few exhausts today can make such an engine speak. The MVT SC can be a good alternative, the SC RACE or SC RACING from MVT too! An old G2 Open can also be a good choice!
It is therefore an ultra-efficient, very torquey and powerful motor that is delivered to you ready to be used on your chassis with a drive and an air filter of your choice. With variable ignition, long stroke, such diagrams, 24mm carburetion... An 11 / 45 transmission can be pulled to 12,000rpm without problems with top acceleration.
Suffice to say that it is in your interest to equip your chassis with brakes and tires worthy of the name!
