I read on another post that lugging (being in a too high gear) an engine too bad can break something. How is this possible?. Thanks

 

Not sure on how much it will break but it will wear your clutch out much faster then if you were to ride in the right gear.

 

Lugging an engine means putting the engine under an extremely stressful load. A common way to lug an engine is to operate it at an extremely low rpm while the transmission is in a higher gear (for instance, leaving the transmission in fourth gear when it should be in second or third where engine speed is better matched to transmission speed). Lugging causes extreme stress between the rear thrust faces of each piston and the cylinder walls. Small bits of piston skirt can break away causing the rear surface to scuff. The best prevention for lugging an engine (either old or new) is to downshift to a lower gear where the engine runs more freely, and the transmission assists the engine in delivering peak power to the rear wheels.

 

Yes it can frag your clutch if severe enough. More likely just burn the plates tho.

 

The term "lugging" doesn't necessarily always have a bad connotation. For instance, the motor in the 400EX or the Warrior will lug down better than the Z400, which likes to rev. The Rancher motor, will REALLY lug down. What lugging down means in this sense is that the motor will perform well at low rpm, has good low end torque, and won't stall easily.

 

I think I've got my answers.... Thanks everybody [img]i/expressions/face-icon-small-happy.gif[/img]
