[@gijsmunster4472]

you´re fking killing that engine that engine with all that engine breaking

[@hugoparox]

Not at all, he is giving it a bit of throttle every now and then. Perfectly fine, that alone keeps the engine lubricated enough.

[@undergrounddrift187]

lmfao they high-tuned that engine just for it to be BLOWN by all that engine-braking

[@flyboyfs]

just finish testing one 2fast 80 stock origem, with 28mm carb and on my dyno gave me 24.6 PS at wheel with out adjusting:) but my crank is Conti rx, not Bidalot

[@flyboyfs]

buenas, que transferencias tienes en este 2fast? Origen no és buena? Hay un punto alto en el puerto de escape debido al perno del cilindro, fue posible limar ese punto alto todo? Trasfer A y B el origen del pistón no está nivelado con el pistón certo?

[@ruben19]

Jajaja el omar dile que no deje que frene tanto de motor que duele oirlo jajajaja

[@mrtzrderbi]

jajjajjajaj

[@claudiolorenzoraia1671]

What about the cylinder studs? Did you need to shorten them to avoid obstructing the flow to the ports?

@@l81x16 it doesnt hurt the engine too much. Learn facts

[@l81x16]

@@joelpyy446 it sure does

[@Reeothec]

this little bit of engine braking probably wont damage the engine. barely any load keeping the engine moving faster then the oil/fuel supply

[@ferreiraaveiro3908]

more power than the two stroke stuffing

[@OskarAxl]
