Hmm, i still don't know what a stroke is can someone please, in easy terms tell me what is the difference between cc and strokes?jonnythan wrote:I just spent 10 minutes wondering why a 2 stroke should be so much more powerful than an equivalent-displacement 4 stroke engine.
I couldn't figure it out. Nothing seemed that different. I was thinking about valving, exhaust, fuel mixtures, etc. I was going nuts. I was about to post here asking, and then I wrote the "4" in 4 stroke and realized what the answer was.
That's my story for the evening. Goodnight
Liar, that 500 made like 170 some hp. But it was in a narrow band and a scary light chassis.Wrider wrote:Just the other day in school we were going over two strokes... In 1991, Honda made a 500cc Parallel Twin 2-Stroke race bike. The racers who rode it were actually scared of it. Why? Over 300 HP. Even the Hayabusa, at 1349 ccs (2008 model) makes a claimed 198 HP, because it's a 4-Stroke... That's the difference... lol

The reason is that a 2-stroke engine has a detonation every rotation of the crankshaft. 4-stroke engines have detonations every *other* rotation of the crankshaft. Hence a 2-stroke engine of similar displacement will produce more power.xornr89 wrote:Hmm, i still don't know what a stroke is can someone please, in easy terms tell me what is the difference between cc and strokes?jonnythan wrote:I just spent 10 minutes wondering why a 2 stroke should be so much more powerful than an equivalent-displacement 4 stroke engine.
