rev-ing at the lights

[N736RA]

Since apparently everyone does it, is there an actual purpose to revving the engine up at a light before taking off? I always figured it would just bother the cars behind me, but if there's a technical reason...thats a different story

If you mean right before taking off, then yes, you have to get the revs up in order to take off properly and not stall. Just revving the engine while in neutral or clutch is completely pulled in, no, there is not a technical reason to do that - only a human one (Wanting to be heard).

If your bike is tuned properly, then there's no technical reason to rev or blip your throttle.

I've been on a few bikes here and there that when warmed up, they would hesitate after sitting at a light idling for a few minutes. Then I'd give the throttle a blip before letting the clutch out.

Not everyone does it. People like me with a stock ACE 750 exhaust would be embarrassed at the results. (Did that dude on the scooter just out-rev me?)

The harley guys do it because of how thier bikes are tuned. The idle is set too low and floats too high. They come to a light and if they don't blip the throttle the Carb floods, or revs drop too much.

Thats just B.S. They are doing it just to do it.

N736RA,

Ignore those other guys who posted; they don't know what they're writing about.

There is a very good technical reason for blipping the throttle while the bike is sitting at a light. It is known by the technical term "stupidity" and is practiced regularly by riders dedicated to proving that loud pipes risk rights.

I always thought it was to say, "Hey, look at me, I'm a big, bad biker and I can make noise". On the other hand maby it's just to keep the bike from stalling at idle. Either way it a strong indication of a problem.

You're not serious with this are you....? I thought you knew better.

Well in the old days if you didn't reve it at the lights on a long wait the carb wold load up and the bike would start to die and the old two strokes, remember those, would foul the plugs. And trust me starting a 63 Bonneville with a flooded carb was no fun, no electric leg then. So you revved to make sure you would keep going. Now days it isn't necessary and unless I get lost in a day dream I don't, but I still remember when.
