Normal
And there are alot people that run 32:1/ 40:1/ 50:1 and so on and I am sure 28:1 and still blow engines. Alot has to do with how you ride. if you are changing gears and keeping the RPMs in the correct range your engine will last longer but running even 28:1 and running WOT in 1st gear 5 miles down the road and it will overheat and scorch/blow the engine. But like most kids there is a learning curve on riding in the correct gear and I wouldn't, again I said I wouldn't run 50:1 in any 2st ever. Unless it is my weedeater
