hey all, i know a little about the engines of these motorcycles, but,....
....i need some answers, i have a little 250cc ( honda rebel engine ) i know its not an high out put engine but i know it can hit 85 mph on the highway ( other riders 250's same engine ),...the thing is when im out riding 55 - 60 mph its fine. when i hit 62, it starts choking, or cutting douwn. going douwn hill i can smooth out near 70. so whats the problem sound like to you guys..???

Loose nut behind the handlebars?

Tune up? Air Filter? Spark Plugs? Spark Plug Wires? Fuel problems? Dirty carbs? Vacuum leaks? Loose wiring?

Could be a lot of things.

Do a thorough check-up

if its brand new it should be under warranty. if its under warranty i would take it in.
